	(scm_readdir): Use readdir64.
	(scm_copy_file): Use open64 and fstat64, to cope with >2Gb files.
	* ports.c (scm_truncate_file): Use truncate64.  Correction truncate
	and ftruncate take off_t not size_t.
	* _scm.h (stat_or_stat64 etc): Macros for selecting LFS64 when
	available.

2006-04-06  Kevin Ryde  <user42@zip.com.au>

	* fports.c (scm_setvbuf): Fix for not _IOLBF, clear SCM_BUFLINE
	instead of toggling it.  Reported by Ludovic Court�s.
	
2006-03-26  Marius Vollmer  <mvo@zagadka.de>

	* threads.c (get_thread_stack_base): Use scm_get_stack_base
	instead of accessing __libc_stack_end directly, and only do this
	when pthread_attr_getstack is known not to work for the main
	thread or when not using pthreads at all.

	* gc_os_dep.c (scm_get_stack_base): Abort when the machine type is
	unknown instead of returning NULL.

2006-03-21  Ludovic Court�s  <ludovic.courtes@laas.fr>

        * numbers.c (scm_i_mem2number): Renamed to
	scm_c_locale_stringn_to_number.

        * numbers.h: Update function declaration.

2006-03-11  Neil Jerram  <neil@ossau.uklinux.net>

	* unif.c (string_set): Don't return in a void function.  (Reported
	by Mike Gran.)

	* srfi-4.c (scm_uniform_vector_read_x): Declare base as char*
	rather than void*, so we can do pointer arithmetic on it.

2006-03-10  Neil Jerram  <neil@ossau.uklinux.net>

	* unif.c (scm_make_shared_array): Don't use SCM_I_ARRAY_BASE when
	oldra is not an array.  (Reported by Steve Juranich.)

	* threads.c (do_unlock): Renamed from "unlock", which is defined
	in unistd.h on QNX.  (Reported by Matt Kraai.)

2006-03-04  Kevin Ryde  <user42@zip.com.au>

	* deprecated.c (scm_i_defer_ints_etc): Show SCM_DEFER_INTS in message,
	not SCM_CRITICAL_SECTION_START.

2006-02-26  Kevin Ryde  <user42@zip.com.au>

	* filesys.c (scm_readdir): Use fpathconf for the dirent size when
	NAME_MAX is not available, which is so on Solaris 10.  Report and help
	by Bill Schottstaedt.

	* srfi-13.c (MY_VALIDATE_SUBSTRING_SPEC_UCOPY): New macro.
	(scm_string_compare, scm_string_compare_ci, scm_string_lt,
	scm_string_gt, scm_string_le, scm_string_ge, scm_string_ci_lt,
	scm_string_ci_gt, scm_string_ci_le, scm_string_ci_ge): In comparisons
	use "unsigned char", not signed char.  This ensures comparisons are
	the same as `char<?' etc, and is also the same as guile 1.6 did.
	Reported by Sven Hartrumpf.

2006-02-19  Mikael Djurfeldt  <mdj@neurologic.cc>

	* random.c: Test for SCM_HAVE_T_UINT64 instead of
	SCM_HAVE_T_INT64.
	(scm_i_uniform32, scm_i_uniform32, scm_i_init_rstate): Use

2006-01-04  Ludovic Court<E8>s  <ludovic.courtes@laas.fr>

        * gc-segment.c (scm_i_sweep_some_cards): Take a SWEEP_STATS
        argument.  Don't refer to SCM_GC_CELLS_COLLECTED and
        SCM_CELLS_ALLOCATED.  If SEG->FIRST_TIME, let CELLS_COLLECTED as zero.
        Take into account SEG->SPAN when computing CELLS_SWEPT.
        (scm_i_sweep_segment): Take one more argument, similarly.
        (scm_i_sweep_all_segments): Likewise.
        (scm_i_sweep_some_segments): Likewise.
        (scm_i_adjust_min_yield): Change the way MIN_CELLS is computed: do not
        refer to SCM_GC_CELLS_COLLECTED.

        * gc-freelist.c (scm_i_adjust_min_yield): Take one more
        argument, an `scm_i_sweep_statistics' object.
        Change the way DELTA is collected: don't take into account
        SCM_GC_CELLS_COLLECTED_1, only SWEEP_STATS.COLLECTED.

        * gc-malloc.c (scm_realloc): Pass an extra argument
        to `scm_i_sweep_all_segments ()'.

        * gc.c (gc_start_stats): Updated accordingly.
        (gc_end_stats): Take an additional SWEEP_STATS argument.
        Decrement SCM_CELLS_ALLOCATED after calls to `scm_i_sweep_* ()'.
        (scm_gc_for_newcell): Updated callers of `scm_i_sweep_*'.
        Decrement SCM_CELLS_ALLOCATED.
        (scm_i_gc): Likewise.

        (scm_i_sweep_statistics_init): New macro.
        (scm_i_sweep_statistics_sum): New macro

2006-02-14  Ludovic Court�s  <ludovic.courtes@laas.fr>

        * strings.c (scm_i_take_stringbufn): Register LEN+1 bytes instead of
	LEN.  Without this, too much collectable memory gets unregistered,
	which results in an underflow of SCM_MALLOCATED in
	`decrease_mtrigger()'.

        * gc-malloc.c (decrease_mtrigger): Make sure SIZE is lower than or
	equal to SCM_MALLOCATED.

2006-02-13  Marius Vollmer  <mvo@zagadka.de>

	* eval.c (scm_eval_body): Use scm_i_dynwind_pthread_mutex_lock
	oinstead of scm_dynwind_pthread_mutex_lock so that it works when
	configured --without-threads.

2006-02-12  Marius Vollmer  <mvo@zagadka.de>

	* unif.c (scm_dimensions_to_uniform_array): Use the prototype for
	filling when the fill parameter is omitted, as documented, but
	turn #\nul into 0 since s8 arrays (signified by a #\nul prototype)
	can not store characters.

2006-02-09  Neil Jerram  <neil@ossau.uklinux.net>

	* socket.c (scm_c_make_socket_address): Pass address_size pointer
	on to scm_fill_sockaddr call.

2006-02-04  Neil Jerram  <neil@ossau.uklinux.net>

	* throw.h (scm_c_catch, scm_c_with_throw_handler,
	scm_catch_with_pre_unwind_handler, scm_with_throw_handler): New.

	* throw.c (SCM_JBPREUNWIND, SCM_SETJBPREUNWIND): New.
	(struct pre_unwind_data): New, replaces struct lazy_catch.
	(scm_c_catch): New, replaces scm_internal_catch as the primary
	catch API for C code; adds pre-unwind handler support.
	(scm_internal_catch): Now just a wrapper for scm_c_catch, for back
	compatibility.
	(tc16_pre_unwind_data, pre_unwind_data_print,
	make_pre_unwind_data, SCM_PRE_UNWIND_DATA_P): Renamed from
	"lazy_catch" equivalents.
	(scm_c_with_throw_handler): New, replaces scm_internal_lazy_catch
	as the primary C API for a "lazy" catch.
	(scm_internal_lazy_catch): Now just a wrapper for
	scm_c_with_throw_handler, for back compatibility.
	(scm_catch_with_pre_unwind_handler): Renamed from scm_catch; adds
	pre-unwind handler support.
	(scm_catch): Now just a wrapper for
	scm_catch_with_pre_unwind_handler, for back compatibility.
	(scm_with_throw_handler): New.
	(scm_lazy_catch): Update comment to say that the handler can
	return, and what happens if it does.
	(toggle_pre_unwind_running): New.
	(scm_ithrow): When identifying the throw target, take running
	flags into account.  In general, change naming of things from
	"lazy_catch" to "pre_unwind".  When throwing to a throw handler,
	don't unwind the dynamic context first.  Add dynwind framing to
	manage the running flag of a throw handler.  If a lazy catch or
	throw handler returns, rethrow the same exception again.  Add
	pre-unwind support to the normal catch case (SCM_JMPBUFP).

	* root.c (scm_internal_cwdr): Add NULL args to
	scm_i_with_continuation_barrier call.

	* dynwind.c: Change comment mentioning lazy-catch to mention
	pre-unwind data and throw handler also.

	* continuations.h (scm_i_with_continuation_barrier): Add
	pre-unwind handler args.

	* continuations.c (scm_i_with_continuation_barrier): Add
	pre-unwind handler args, and pass on to scm_c_catch (changed from
	scm_internal_catch).
	(c_handler): Remove scm_handle_by_message_noexit call.
	(scm_c_with_continuation_barrier): Call
	scm_i_with_continuation_barrier with scm_handle_by_message_noexit
	as the pre-unwind handler.
	(scm_handler): Remove scm_handle_by_message_noexit call.
	(s_scm_with_continuation_barrier): Call
	scm_i_with_continuation_barrier with scm_handle_by_message_noexit
	as the pre-unwind handler.

2006-02-04  Kevin Ryde  <user42@zip.com.au>

	* gc-mark.c (scm_mark_all): Fix c99-isms "loops" and "again" variables.

2006-02-03  Kevin Ryde  <user42@zip.com.au>

	* list.c, list.h (scm_list): Restore this function for use from C.
	It's a complete no-op but in theory might used by someone.

2006-01-30  Marius Vollmer  <mvo@zagadka.de>

	* eval.c (scm_eval_body): Lock source_mutex with a dynwind context
	so that it gets unlocked in all cases.
	(SCM_APPLY, CEVAL): Likewise.

2006-01-29  Marius Vollmer  <mvo@zagadka.de>

	* ramap.c: (scm_array_map_x): Don't use scm_array_p, use
	scm_is_typed_array instead.

	Renamed the "frames" that are related to dynamic-wind to "dynamic
	contexts.  Renamed all functions from scm_frame_ to scm_dynwind_.
	Updated documentation.

	Disabled "futures":

	* futures.h, futures.c: Wrap whole contents in "#if 0"/"#endif".
	* eval.c, init.c: Comment out all 'future' related things.

2006-01-28  Marius Vollmer  <mvo@zagadka.de>

	* inline.h, pairs.c (scm_is_pair): Moved scm_is_pair from pairs.c
	to inline.h to make it inline.

2005-12-19  Ludovic Court�s  <ludovic.courtes@laas.fr>

        * strings.c (scm_i_take_stringbufn): New.
        (scm_i_c_take_symbol): New.
        (scm_take_locale_stringn): Use `scm_i_take_stringbufn ()'.

        * strings.h (scm_i_c_take_symbol): New.
        (scm_i_take_stringbufn): New.

        * symbols.c  (lookup_interned_symbol): New function.
        (scm_i_c_mem2symbol): New function.
        (scm_i_mem2symbol): Use `lookup_symbol ()'.
        (scm_from_locale_symbol): Use `scm_i_c_mem2symbol ()'.  This avoids
        creating a new Scheme string.
        (scm_from_locale_symboln): Likewise.
        (scm_take_locale_symbol): New.
        (scm_take_locale_symboln): New.

        (scm_take_locale_symboln): New.

2006-01-18  Han-Wen Nienhuys  <hanwen@xs4all.nl>

	* gc-card.c ("sweep_card"): don't count scm_tc_free_cell for
	free_count.

2005-11-29  Han-Wen Nienhuys  <hanwen@xs4all.nl>

	* regex-posix.c (s_scm_regexp_exec): list the offending pattern
	upon error

2005-12-29  Neil Jerram  <neil@ossau.uklinux.net>

	the GC when allocated_fluids_len is zero.

2005-12-14  Neil Jerram  <neil@ossau.uklinux.net>

	* load.c (the_reader, the_reader_fluid_num): New.
	(scm_primitive_load): Support custom reader.
	(scm_init_load): Init the_reader and the_reader_fluid_num; export
	the_reader as `current-reader'.

	* scmsigs.c (do_read_without_guile): Use the "raw_data" passed in
	(rather than an uninitialized pointer on the stack).

2005-12-07  Marius Vollmer  <mvo@zagadka.de>

	Reported by Bruce Korb:
	
	* init.c (invoke_main_func): Don't call exit here.  Throws that
	are only caught by scm_with_guile will bypass us and would cause
	scm_boot_guile to return erroneously.
	(scm_boot_guile): Expect scm_with_guile to return and call exit
	here, passing it an appropriate exit code.

	From Andy Wingo:
	
	* script.c (scm_find_executable): Compile fix -- fgetc returns an
	unsigned char cast to an int, or -1 for EOS.
	
2005-12-06  Marius Vollmer  <mvo@zagadka.de>

	* srfi-4.h, srfi-4.c, srfi-4.i.c (take_uvec): Make BASE pointer

	scm_enter_guile): Removed from public API.  See comment at
	scm_without_guile for the rationale.

	* scmsigs.c (read_without_guile): New.
	(signal_delivery_thread): Use it instead of
	scm_leave_guile/read/scm_enter_guile.

	From Stephen Compall:

	* eval.c (scm_m_cond): Recognize SRFI 61 cond syntax.
	(CEVAL): Evaluate SRFI 61 cond clauses.

2005-12-06  Ludovic Court�s  <ludovic.courtes@laas.fr>

	* gc-card.c (scm_i_card_statistics): Return if BITVEC is NULL.
	This was typically hit when running `gc-live-object-stats' right
	after starting Guile.

2005-11-30  Kevin Ryde  <user42@zip.com.au>

	* srfi-13.c (scm_string_append_shared): No copying if just one
	non-empty string in args.

2005-11-26  Kevin Ryde  <user42@zip.com.au>

	* gc-mark.c (scm_mark_all): Change C++ comment to C comment.  Reported
	by Ludovic Court�s.

	* list.c (list): Should be "primitive" in SCM_SNARF_DOCS, not
	"register".

	* random.c (scm_i_copy_rstate, scm_c_make_rstate): Don't test for
	scm_malloc returning NULL, it never does that.
	* putenv.c (putenv): Likewise.

	* socket.c (scm_fill_sockaddr): Remove SCM_C_INLINE_KEYWORD, this is
	much too big to want to inline.

2005-11-17  Ludovic Court�s  <ludovic.courtes@laas.fr>

	* print.c (EXIT_NESTED_DATA): Before popping from the stack, reset
	the value at its top.  This fixes a reference leak.
	(PUSH_REF): Perform `pstate->top++' after calling
	`PSTATE_STACK_SET ()' in order to avoid undesired potential side
	effects.

2005-11-12  Ludovic Court�s  <ludovic.courtes@laas.fr>

	* gc.c (scm_weak_vectors): Removed.

2005-11-12  Kevin Ryde  <user42@zip.com.au>

	* socket.c (scm_setsockopt): Missing @defvar in docstring.  Reported
	by Ludovic Court�s.

2005-11-07  Marius Vollmer  <mvo@zagadka.de>

	* stime.c (scm_mktime): Use scm_frame_critical_section instead of
	SCM_CRITICAL_SECTION_START/END since the code inside the critical
	section might exit non-locally.

2005-11-04  Neil Jerram  <neil@ossau.uklinux.net>

	* eval.c (sym_instead): New symbol.
	(ENTER_APPLY): Remove optional use of a continuation when making
	trap call.
	(scm_debug_opts): Change doc for 'cheap option to make clear that
	it is now obsolete.

	making trap calls, and implement substitution of eval expressions
	and return values using the values that the trap call handlers
	return.

	* debug.h (SCM_CHEAPTRAPS_P): Removed.

2005-10-27  Ludovic Court�s  <ludovic.courtes@laas.fr>

2005-10-24  Kevin Ryde  <user42@zip.com.au>

	* socket.c (scm_init_socket): Add IPPROTO_IP, IPPROTO_TCP,
	IPPROTO_UDP.  Remove SOL_IP, SOL_TCP, SOL_UDP.  The former are in
	POSIX spec examples, the latter are not available on for instance
	NetBSD.

	* socket.c (scm_getsockopt, scm_setsockopt): Update docstrings from
	posix.texi.

	* stime.c (scm_strftime): Update docstring from posix.texi.

	(scm_threads_prehistory): Initialize
	scm_i_pthread_mutexattr_recursive and scm_i_critical_section_mutex
	here.
	
	* eval.c (source_mutex): Do not initialiaze statically.

	scm_i_pthread_mutexattr_recursive.

2005-09-05  Marius Vollmer  <mvo@zagadka.de>

	* print.h (SCM_PRINT_KEYWORD_STYLE_I, SCM_PRINT_KEYWORD_STYLE):

2005-08-15  Neil Jerram  <neil@ossau.uklinux.net>

	* eval.c (eval_letrec_inits): New.

	scm_string_filter, scm_string_delete): Use scm_t_trampoline_1 for
	procedures called in loops.

2005-08-02  Kevin Ryde  <user42@zip.com.au>

	* strports.c (st_flush): Increase buffer by 1.5x when growing, to
	avoid lots of copying where previoulsy growing by only 80 bytes at a
	time.

2005-08-01  Marius Vollmer  <mvo@zagadka.de>

	* modules.h, modules.c (scm_eval_closure_module): Removed, we
	already have scm_lookup_closure_module, which does the same thing.
	
2005-08-01  Marius Vollmer  <mvo@zagadka.de>

	New marking algorithm for weak hashtables that fixes the problem
	that references from the non-weak value to the associated weak
	key (for example) would prevent the entry from ever being dropped.

	Guardians have been changed back to their original semantics and
	are no longer greedy and no longer drop cycles.
	
	* gc-mark.c (scm_mark_all): Do not rely on hooks to run the weak
	hashtable and guardian machinery but call the relevant functions
	directly.

	* guardians.h, guardians.c, deprecated.h,
	deprecated.c (scm_destroy_guardian_x, scm_guardian_greedy_p,
	scm_guardian_destroyed_p, scm_guard, scm_get_one_zombie):
	Deprecated and moved into deprecated.[ch].

	* guardians.h, guardians.c: Mostly rewritten.

	scm_i_identify_inaccessible_guardeds,
	scm_i_mark_inaccessible_guardeds): New.
	(scm_make_guardian): Removed greedy_p argument.
	
	* weaks.h, weaks.c (SCM_I_WVECT_TYPE, SCM_I_SET_WVECT_TYPE): New.

	(hashtable_print): Use SCM_HASHTABLE_N_ITEMS instead of
	t->n_items.
	(scan_weak_hashtables, scm_i_scan_weak_hashtables): Renamed former
	to latter.  Do not scan the alists themselves, this is done by the
	weak vector code now.  Just update the element count.

	* vectors.h (SCM_I_WVECT_TYPE, SCM_I_WVECT_EXTRA): Renamed former
	to latter.  The type is now only part of the cell word.

	* hashtab.c (scm_i_rehash): Cast SCM_HASHTABLE_FLAGS (table) to
	scm_t_bits before storing them in the type word.
	
	* gc.c (tag_table_to_type_alist): Modified type of c_tag from
	scm_t_bits to int.

2005-07-12  Kevin Ryde  <user42@zip.com.au>

	* eval.c (scm_dbg_make_iloc): Should be SCM_IFRAMEMAX and
	SCM_IDISTMAX, and cast uints through scm_t_bits to make gcc happy.
	* pairs.c (scm_error_pair_access): Use scm_from_locale_string rather
	than scm_makfrom0str.
	Reported by Ken Raeburn.
	
	* gc-card.c (scm_dbg_gc_get_bvec): Change return from long* to
	scm_t_c_bvec_long*, gcc 4 doesn't like different pointer targets when
	returning SCM_GC_CARD_BVEC.
	
	* pairs.c (scm_error_pair_access): Plain ascii ' in error message
	rather than latin-1 acute accent, the latter may not print on all
	terminals.

	* srfi-13.c (scm_string_filter, scm_string_delete): Strip leading and
	trailing deletions, so as to return a substring if those are the only
	changes.

2005-07-10  Kevin Ryde  <user42@zip.com.au>

	* socket.c (scm_inet_pton, scm_inet_ntop): Pointer cast to scm_t_uint8
	for scm ipv6 funcs, gcc 4 is picky about char* vs uchar*.
	(scm_getsockopt, scm_accept, scm_getsockname, scm_getpeername,
	scm_recvfrom) Use socklen_t, gcc 4 is picky about int* vs socklen_t*.

2005-07-01  Han-Wen Nienhuys  <hanwen@xs4all.nl>

	* gc-card.c (scm_i_card_statistics): init tag.

	* gc.c (tag_table_to_type_alist): check type of tag. Should be integer.

2005-06-18  Han-Wen Nienhuys  <hanwen@xs4all.nl>

	* fports.c (s_scm_open_file): add the b flag for binary to the doc
	string.

2005-06-25  Kevin Ryde  <user42@zip.com.au>

	* srfi-13.c (scm_string_filter, scm_string_delete): Partial revert
	last change, use plain copy-on-write substrings, the individual
	descriptions in the srfi don't mention shared storage (only the
	introduction does).

	* strings.c (scm_take_locale_stringn): Use realloc to make room for
	null-terminator, rather than mallocing a whole new block.
	(scm_take_locale_string): Use scm_take_locale_stringn len==-1.

2005-06-12  Marius Vollmer  <mvo@zagadka.de>

	* ramap.c (scm_array_index_map_x): First test for real arrays,
	then check for generalized vectors.  This ensures that the
	generalized vector case need only work with zero-origin ranges.
	(scm_ra_eqp, scm_ra_compare): Use the new array handle functions
	to access the target array, making these functions work with all
	kinds of arrays, not just bit arrays.

	* gh.h, gh_data.c, gh_eval.c, gh_funcs.c, gh_init.c, gh_io.c,
	gh_list.c, gh_predicates.c: Deprecated everything.

	* environments.c (environment_default_folder,
	environment_default_observer): Do not use gh_call3, gh_call1.

2005-06-10  Han-Wen Nienhuys  <hanwen@xs4all.nl>

	* modules.c (s_scm_eval_closure_module): new function. Return the
	module inside an eval-closure.

	* gc.c (scm_init_storage): make scm_stand_in_procs a weak_key hash
	table. This means that procedure properties are GC'd if the
	procedure dies.

2005-06-11  Kevin Ryde  <user42@zip.com.au>

	* srfi-13.c (scm_string_filter, scm_string_delete): For char and
	charset cases, count chars kept and build a string in a second pass,
	rather than using a cons cell for every char kept.  Use a shared
	substring when nothing removed (such sharing is allowed by the srfi).

2005-06-09  Han-Wen Nienhuys  <hanwen@xs4all.nl>

	* gc.c (tag_table_to_type_alist): convert tag number to "tag %d"
	string, so live object stats can be sorted with string<?. 

2005-06-06  Marius Vollmer  <mvo@zagadka.de>

	* print.c (iprin1): When writing a string, collect all characters
	that can be printed directly into one call to scm_lfwrite.
	Previously, every character was output with its own call to
	write(2) on unbuffered ports.

	* eval.c (scm_eval_options_interface): Use
	scm_frame_critical_section instead of SCM_CRITICAL_SECTION_START
	and SCM_CRITICAL_SECTION_END.

	* unif.c (scm_array_in_bounds_p): First test for real arrays, then
	check for generalized vectors.  This ensures that the generalized
	vector case need only work with zero-origin ranges.

2005-06-06  Kevin Ryde  <user42@zip.com.au>

	* srfi-13.c (scm_string_split): Compare char/char in scan.  Mixing an
	unsigned int SCM_CHAR and a char string meant an 8-bit char was never
	matched.

2005-06-05  Marius Vollmer  <mvo@zagadka.de>

	* eval.c: Added comment on how to make case 1.1 of
	r5rs_pitfall.test succeed.

	From Jan Nieuwenhuizen <janneke@gnu.org>. Thanks!

 	* hashtab.h: Bugfix: use SCM_API (WAS: extern).
 
 	* socket.c: Remove obsolete comment about socklen_t.
 	(s_scm_setsockopt)[!HAVE_IP_MREQ]: Do not use ip_mreq code.
 
 	* numbers.h (isnan)[__MINGW32__]: Remove.
 
 	* Makefile.am (gen_scmconfig_SOURCES): Bugfix: Add
 	DEFAULT_INCLUDES when cross compiling.
 
 	* threads.c (ETIMEDOUT, pipe)[__MINGW32__]: Add defines.

 	* stime.c (scm_strftime)[!HAVE_TM_ZONE]: Use
	SCM_SIMPLE_VECTOR_REF instead of SCM_VELTS.  (Changed slightly
	from Jan's patch.)
 
2005-05-22  Marius Vollmer  <mvo@zagadka.de>

	* unif.c (scm_make_shared_array): Add old base to new base since
	scm_array_handle_pos does not include the base.
	(scm_aind): Likewise.

	* ports.c (scm_putc, scm_puts): Assert that the port argument is a
	output port.

2005-05-12  Neil Jerram  <neil@ossau.uklinux.net>

	Mac OS X compile warning fixes, reported by Richard Todd.
	
	* unif.c (scm_i_read_array): Declare rank as ssize_t, to guarantee
	that it is signed.

	* strports.c (st_resize_port): Add unsigned char cast.
	(scm_mkstrport): Make read/write_buf cast unsigned.

	* srfi-13.c (string_titlecase_x): Add unsigned char cast.

	* rdelim.c (scm_read_line): Initialize slen.

	* load.c (scm_search_path): Remove weird >=1, and add
	parentheses to clarify conditions.

	* hash.c (scm_hasher): Add const unsigned char cast.

	* gh_data.c (gh_chars2byvect): Add scm_t_int8 cast.

2005-05-11  Neil Jerram  <neil@ossau.uklinux.net>

	Fix C99isms reported by Ludovic Court�s:
	
	* threads.c (s_scm_lock_mutex): Don't declare msg in middle of
	code.

	* gc.c (s_scm_gc_live_object_stats): Don't declare alist in middle
	of code.

	* gc-card.c (scm_i_card_statistics): Don't declare tag in middle
	of code.
	(scm_i_card_statistics): Add block for declarations of tag_as_scm
	and current.

2005-05-10  Neil Jerram  <neil@ossau.uklinux.net>

	* scmsigs.c (signal_delivery_thread): Return a value, to avoid
	compile warning reported by Werner Scheinast.

2005-04-30  Han-Wen Nienhuys  <hanwen@xs4all.nl>

	* list.h: remove scm_list()

	* fluids.c (DYNAMIC_STATE_NEXT_LOC): new macro for use with
	SCM_DEBUG_CELL_ACCESSES
	(FLUID_NEXT_LOC): idem.

2005-04-30  Kevin Ryde  <user42@zip.com.au>

	* numbers.c (scm_divide): Correction to 1/complex and <any>/complex,
	need to test abs(re)<abs(im) for choice of cases, otherwise divide by
	zero when re==0 and im<0.  Reported by Jean Crepeau.

2005-04-25  Kevin Ryde  <user42@zip.com.au>

	* ramap.c (scm_array_map_x): Allow no source args, add num args checks
	to subr_1, subr_2, subr_2o and dsubr cases.  No source args only has a
	few sensible uses (like filling with a random number generator say),
	but has been allowed in the past and so should be kept.

2005-04-23  Kevin Ryde  <user42@zip.com.au>

	* hashtab.c (scm_hashx_remove_x): Need to pass "closure" to
	scm_hash_fn_remove_x.

	* list.c (scm_cons_star): Don't modify the rest list, it belongs to
	the caller when cons* is reached through apply.

	* list.c (list): Use scm_list_copy, so as to produce a fresh list when
	list is called using apply, under the debugging evaluator.
	(scm_list): Remove.

	* list.c, list.h (scm_make_list): New code, moving make-list from
	boot-9.scm.

2005-04-14  Kevin Ryde  <user42@zip.com.au>

	* numbers.c, numbers.h (scm_oneplus, scm_oneminus): New functions,
	converted from scheme code in boot-9.scm.

2005-04-11  Kevin Ryde  <user42@zip.com.au>

	* srfi-13.c (scm_string_concatenate, scm_string_concatenate_shared):
	Validate list argument, scm_string_append and scm_string_append_shared
	don't do that to their rest argument (in a normal build).

2005-04-04  Marius Vollmer  <marius.vollmer@uni-dortmund.de>

	* hashtab.h, hashtab.c (scm_t_hashtable): Removed 'closure' field.  The
	closure can not be stored since it is no longer valid at GC time.
	(make_hash_table): Initialize 'hash_fn' field.
	(scm_i_rehash): Only store hash_fn in hash table when closre is
	NULL.
	(rehash_after_gc): Only call scm_i_rehash when 'hash_fn' is
	non-NULL.  Always use a NULL closure.
	(scm_hash_fn_create_handle_x): Also rehash when table contains too
	few entries.
	
2005-03-29  Marius Vollmer  <marius.vollmer@uni-dortmund.de>

	* hashtab.h, hashtab.c (scm_hash_fx_remove_x): Removed delete_fn
	argument; always use scm_delq_x.  The delete_fn function works on
	the handle, not the key, and it therefore makes no sense to make
	it configurable.  Changed all callers.
	(scm_hashx_remove_x): Likewise.  Also, exported to Scheme.
	(scm_hash_clear): Accept plain vectors as hashtables.
	(scm_delx_x): Removed.
	
2005-03-28  Han-Wen Nienhuys  <hanwen@xs4all.nl>

	* inline.h (scm_double_cell): use __asm__ iso. asm, to maintain
	compatibility with gcc -std=c99.

2005-03-24  Mikael Djurfeldt  <djurfeldt@nada.kth.se>

	* async.h (scm_mask_ints): Removed left over reference to
	scm_root.

	* threads.c: Removed fprintf debug statements.
	
2005-03-24  Neil Jerram  <neil@ossau.uklinux.net>

	* debug.c (scm_make_memoized): Remove unnecessary critical
	section, and simplify by using SCM_RETURN_NEWSMOB.

2005-03-20  Mikael Djurfeldt  <djurfeldt@nada.kth.se>

	* strings.h (SCM_STRING_UCHARS): Added missing argument.

2005-03-18  Kevin Ryde  <user42@zip.com.au>

	* arbiters.c (FETCH_STORE) [generic C]: Should be
	scm_i_scm_pthread_mutex_lock/unlock now.  Reported by Ludovic Court�s.

2005-03-13  Kevin Ryde  <user42@zip.com.au>

	* numbers.c, numbers.h (scm_i_clonebig): Remove static, so can use in
	srfi-60.

	* numbers.c (scm_logior): Must scm_i_normbig results as per scm_logand,
	because OR-ing bits into a negative can reduce the value to an inum.

	* numbers.c (scm_num_eq_p): On 64-bit systems, be careful about
	casting inum to double since that can lose precision.

2005-03-10  Marius Vollmer  <marius.vollmer@uni-dortmund.de>

	* threads.h, threads.c (scm_i_thread): Added gc_running_p field.
	(guilify_self_1): Initialize it.

	* gc.h, gc.c (SCM_FREECELL_P): Removed for good.
	(scm_block_gc, scm_gc_heap_lock): Removed.  Removed all uses.
	(scm_gc_running_p): Now a macro that refers to the scm_i_thread
	field.
	(scm_i_sweep_mutex): Now a non-recursive mutex.  GC can not happen
	recursively.
	(scm_igc, scm_i_gc): Renamed former to latter.  Changed all uses.
	Do not lock scm_i_sweep_mutex, which is now non-recursive, or set
	scm_gc_running_p.  Do not run the scm_after_gc_c_hook.
	(scm_gc): Lock scm_i_sweep_mutex, set scm_gc_running_p and run the
	scm_after_gc_c_hook here.
	(scm_gc_for_new_cell): Set scm_gc_running_p here and run the
	scm_after_gc_c_hook when a full GC has in fact been performed.
	(scm_i_expensive_validation_check): Call scm_gc, not scm_i_gc.

	* gc-segment.c (scm_i_get_new_heap_segment): Do not check
	scm_gc_heap_lock.

	* gc-malloc.c (scm_realloc, increase_mtrigger): Set
	scm_gc_running_p while the scm_i_sweep_mutex is locked.

	* inline.h (scm_cell, scm_double_cell): Do not check
	scm_gc_running_p, allocation during sweeping is OK.

	* gdbint.c (SCM_BEGIN_FOREIGN_BLOCK, SCM_END_FOREIGN_BLOCK): Do
	not set scm_block_gc.

	* init.c (scm_i_init_guile): Do not set scm_block_gc.

	* deprecation.c (scm_c_issue_deprecation_warning): Use malloc
	instead of scm_malloc.  The latter can not be used during GC.

2005-03-09  Marius Vollmer  <mvo@zagadka.de>

	* script.c (scm_compile_shell_switches): Added 2005 to Copyright
	years.

2005-03-09  Marius Vollmer  <marius.vollmer@uni-dortmund.de>

	* gc-card.c (scm_i_sweep_card): Do not increase/decrease
	scm_gc_running_p.  Sweeping can happen in parallel with
	allocation.

	* inline.h: Updated comments for current threading implementation.

	* threads.h, threads.c (scm_i_frame_single_threaded): Removed.
	(scm_i_thread): Removed unused signal_asyncs field.
	(threads_mark): Do not mark it.
	(guilify_self_1): Do not initialize it.  Do initialize
	continuation_root field.

	(on_thread_exit): Do it here, after leaving guile mode.
	(sleep_level): Removed.
	(scm_i_thread_put_to_sleep): Leave thread_admin_mutex locked when
	returning.  Do not support recursive sleeps.
	(scm_i_thread_wake_up): Expect thread_admin_mutex to be locked on
	entry.  Do not support recursive sleeps.

	resize_all_states): Collapsed ensure_state_size and
	ensure_all_state_sizes into one function named resize_all_states.
	Allocate new vectors outside of single threaded region.  Do only
	simple things inside that region.
	 (scm_make_fluid, scm_make_dynamic_state): Lock fluid_admin_mutex
	while adding to the global lists.
	

2005-03-08  Marius Vollmer  <mvo@zagadka.de>

	libltdl is no longer distributed.  We expect it to be installed
	already.
	
	* Makefile.am (INCLUDES): Removed @LTDLINCL@.
	(libguile_la_LIBADD): Removed @LIBLTDL@.

2005-03-07  Marius Vollmer  <mvo@zagadka.de>

	* threads.h, async.h, threads.c (SCM_CRITICAL_SECTION_START,
	SCM_CRITICAL_SECTION_END): Moved here from threads.h since now
	they also block/unblock execution of asyncs and call
	scm_async_click which is declared in async.h but threads.h can not
	include async.h since async.h already includes threads.h.
	(scm_i_critical_section_level): New, for checking mistakes in the
	use of the SCM_CRITICAL_SECTION_* macros.
	(scm_i_critical_section_mutex): Make it a recursive mutex so that
	critical sections can be nested.

	* throw.c (scm_ithrow): Abort when scm_i_critical_section_level is
	not zero.
	
	* threads.h, threads.c (scm_frame_lock_mutex): New.

	(framed_critical_section_mutex): New, used as default for above.
	(scm_init_threads): Initialize it.
	(scm_threads_prehistory): Do not initialize thread_admin_mutex and
	scm_i_critical_section_mutex; both are initialized statically.
	
	* continuation.c, deprecated.c, goops.c, guardians.c keywords.c,
	libguile_la-arrays.loT, objprop.c, ports.c, smob.c, sort.s,
	srcprop.c, stime.c, struct.c, throw.c, regex-posix.c: Include
	"libguile/async.h" for SCM_CRITICAL_SECTION_START/END.

	* debug.c (scm_debug_options): Replace
	SCM_CRITICAL_SECTION_START/END with a frame and
	scm_frame_critical_section.

	* continuations.c (scm_make_continuation): No longer a critical
	section.
	(scm_dynthrow):  Abort when scm_i_critical_section_level is
	not zero.
	
2005-03-04  Marius Vollmer  <marius.vollmer@uni-dortmund.de>

	* threads.c (scm_try_mutex): Renamed argument for consistency.

	* root.c (scm_call_with_dynamic_root): New docstring.

	* eval.c: Define _GNU_SOURCE.

2005-03-02  Marius Vollmer  <marius.vollmer@uni-dortmund.de>

	Big merge from the mvo-thread-cleanup branch. The main changes
	are:
	
	- The dynamic roots functionality has been split into dynamic
	  states and continuations barriers.  Fluids have been
	  reimplemented and can now be garbage collected.
	
	- Initialization of Guile now works in a multi-thread friendly
	  manner.  Threads can freely enter and leave guile mode.

	- Blocking on mutexes or condition variables or while selecting
	  can now be reliably interrupted via system asyncs.

	- The low-level threading interface has been removed.

	- Signals are delivered via a pipe to a dedicated 'signal delivery
	  thread'.
	
	- SCM_DEFER_INTS, SCM_ALLOW_INTS etc have been deprecated.

	(scm_init_feature): Allocate it.  Also, only add "threads" feature
	when SCM_USE_PTHREAD_THREADS is true.
	
	* eval.c (scm_makprom): Use scm_make_recursive_mutex instead of
	scm_make_rec_mutex, with all the consequences.
	(scm_eval_x, scm_eval): Use scm_frame_begin etc instead of

	* unif.c (prototype_to_type): Bugfix: Don't compare prototype to
	the prototypical examples mentioned in the old reference manual.
	Instead keep the old semantics of dispatching on type.  (Yes, this

	integer-expt and multiply/divide.  Inexacts and fractions no longer
	supported (they happened to work before for left shifts, but not
	right).  Don't really need inexacts and fractions, since ash is
	documented as a "bitwise operation", and all the rest of those only
	take exact integers.

	(scm_flock): Update docstring from manual.

	* random.c (scm_i_init_rstate): Compare w to -1 not 0xffffffffUL, now

	Enclosed arrays are now their own smob.  This has been done to
	make the code more explicit about them and to prepare for the time
	when generalized vectors include arbitrary one-dimensional
	arrays. (Uptonow, enclosed arrays have been recognized by their
	use of an array as their storage 'vector'.  When all generalized
	vectors are allowed as storage, including one-dimensional arrays,
	this will no longer work.)

	(scm_cvref): Use scm_i_cvref.

	given. Use scm_i_cvref to do the actual access.
	("uniform-array-set1"): Do not register.
	(scm_array_set_x, scm_uniform_array_read_x,
	scm_uniform_array_write): Handle enclosed arrays explicitly.

	latter.  Tag "a" is in the table now, no need to handle it as a
	legacy tag.
	(scm_raprin1): Just call scm_iprin1.

	explicitly.

	* ramap.c (cind): Changed second arg to be pointer to long instead
	of uniform vector.
	(scm_ramapc): Allocate index vector with scm_malloc and not as
	uniform vector.  Wrap it in a frame so that it gets properly freed.
	(scm_array_index_map_x): Likewise.

	* unif.c: Changed all uses of scm_array_prototype to
	scm_array_creator. (scm_i_get_old_prototype): Signal error when no
	prototype is known.
	(scm_uniform_array_read_x, scm_uniform_array_write): Reimplemented
	in terms of scm_uniform_vector_read_x and

	declarations.

	* pairs.c (scm_i_chase_pairs): Replace scm_t_bits with

2004-10-27  Marius Vollmer  <marius.vollmer@uni-dortmund.de>

	First cut at integrating uniform vectors from srfi-4 with the rest
	of Guile.  This change replaces scm_tc7_byvect with a s8 uniform
	vector.  The plan is to gradually replace one type after the other
	until none is left and then to consider general cleanups and
	optimizations.

2004-10-20  Marius Vollmer  <mvo@zagadka.de>

	* sort.c (quicksort): Copy pivot out of the array while
	constructing the partitions; it could get overwritten otherwise.
	Because of the ultimate insertion sort, this bug did not cause
	quicksort to fail, it just put all the burdon on the insertion

	scm_i_string_char, scm_i_string_writable_chars): Use it.
	(scm_i_substring_copy): Make START argument optional for C

	* eval.c (scm_lookupcar1): Report "Variable used before given a
	value" insetad of an "Unbound" one for variables that are found

	* posix.c (scm_mkstemp): Correction to the correction, mkstemp
	expects a null-terminated string in the locale encoding, but
	scm_i_string_writable_chars doesn't give that.  Fixed by letting
	mkstemp modify a locale version of the tmpl argument and copying
	the result back into tmpl.

	(scm_mode_bits): Use it.
	(scm_c_port_for_each): Blocking GC does not seem to work, allocate
	a vector normally and fill that instead of consing a list with a
	blocked GC.

	* read.c (scm_i_casei_streq): New, for counted strings.

	* threads.c (gc_section_count): Removed, thread-sleeping can not
	be nested.
	(scm_i_thread_put_to_sleep): Call scm_i_leave_guile before locking

	for speed on i386, otherwise using mutex.

	* eq.c (scm_equal_p): Remove real==fraction and fraction==real, they
	must be #f according to R5RS.  (equal? follows eqv?, and for eqv? an
	exact and inexact is #f.)

	* fports.c (fport_print): Use scm_ttyname instead of ttyname directly,
	to get thread safety of scm_ttyname.

	* ports.c (ttyname): Remove prototype, unused.

	* socket.c (scm_init_socket): Add SOCK_SEQPACKET and SOCK_RDM.

	strings.c have.
	(SCM_STRING_MAX_LEN): Do not hardcode to 24 bits, compute from
	SCM_T_BITS_MAX.
	(scm_is_string, scm_from_locale_string, scm_from_locale_stringn,

	not as a pointer.  Use scm_remember_upto_here_1 to protect it.

	* read.c (scm_input_error): Use a SCM value for 'fn', not a C
	string.  This avoids a conversion round-trip.

	* gh_data.c: Replaced SCM_STRINGP, SCM_STRING_CHARS, and

	terms of scm_to_locale_stringbuf and so that it is thread safe.

	* error.c (scm_error_scm): Throw directly instead of calling
	scm_error, this avoids the back and forth conversion of SUBR and
	MESSAGE and also plugs a memory leak.
	(scm_error): Call scm_error_scm.
	
	* backtrace.c: Replaced SCM_STRINGP with scm_is_string.
	(display_header): Print FNAME when it is true, not
	merely when it is a string.

	* net_db.c (scm_resolv_error): don't cause an exception while
	trying to throw an exception -- call scm_misc_error with correct

	wasn't in any of the format strings.

2004-08-06  Kevin Ryde  <user42@zip.com.au>

	* ramap.c (scm_array_fill_x): For byvect char fill, force signed char
	so as not to depend on signedness of plain char.  For byvect range
	check, throw out-of-range rather than wrong-type-arg.

	signed byte range checks by using scm_to_schar and scm_from_schar,
	don't want to depend on signedness of C char.

2004-08-05  Kevin Ryde  <user42@zip.com.au>

	* arbiters.c (scm_try_arbiter): Use scm_i_misc_mutex instead of

	guaranteed if multiple threads compete to unlock.
	Update docstrings per doc/ref/api-scheduling.texi.

	* filesys.c (scm_copy_file): Use fstat on the input fd rather than
	stat on the filename, to be certain a file rename can't mean we get
	info on one filesystem object but open another.  This fstat usage is
	similar to Emacs copy-file.
	
	* posix.c (scm_setgroups): Enhance docstring, per doc/ref/posix.texi.

	* simpos.c (scm_system_star): Change scm_from_long to scm_from_int on

	(scm_num2float, scm_num2double): Discouraged by moving prototype
	to discouraged.h and rewriting in terms of scm_to_double.
	Replaced all uses with scm_to_double.
	(scm_to_double): Do not implement in terms of scm_num2dbl, use
	explicit code.
	(scm_from_double): Do not implement in terms of scm_make_real, use
	explicit code.

	SCM_T_INT32_MIN, SCM_T_INT32_MAX, SCM_T_UINT32_MAX,
	SCM_T_INT64_MIN, SCM_T_INT64_MAX, SCM_T_UINT64_MAX,
	SCM_T_INTMAX_MIN, SCM_T_INTMAX_MAX, SCM_T_UINTMAX_MAX): Moved
	definition into __scm.h, using new SCM_I_TYPE_MIN, etc.
	
	* conv-integer.i.c, conv-uinteger.i.c: New files, used to generate
	the functions below.

	* Makefile.am (noinst_HEADERS): Added conv-integer.i.c and
	conv-uinteger.i.c.

	* numbers.c, numbers.h (scm_to_int8, scm_to_uint8, scm_to_int16,
	scm_to_uint16, scm_to_int32, scm_to_uint32, scm_to_int64,
	scm_to_uint64, scm_from_int8, scm_from_uint8, scm_from_int16,
	scm_from_uint16, scm_from_int32, scm_from_uint32, scm_from_int64,
	scm_from_uint64): Turned from macros into proper functions.
	(scm_to_signed_integer, scm_to_unsigned_integer,
	scm_from_signed_integer, scm_from_unsigned_integer): Generate via
	conv-integer.i.c and conv-uinteger.i.c, as well.
	
	* number.h (scm_to_ssize_t, scm_to_size_t): Use the new
	SCM_I_SSIZE_MIN, SCM_I_SSIZE_MAX, and SCM_I_SIZE_MAX macros for
	the limits.  Those are always defined.
	
2004-07-29  Kevin Ryde  <user42@zip.com.au>

	* posix.c (scm_ttyname): Use scm_i_misc_mutex for thread safety.

2004-07-28  Kevin Ryde  <user42@zip.com.au>

	* posix.c (scm_ctermid): Use an L_ctermid buf on the stack, for thread
	safety.

	* unif.c (scm_array_set_x): For svect, use scm_num2short for
	consistency with other vector types and to get arg and func name into
	error message.

2004-07-27  Marius Vollmer  <marius.vollmer@uni-dortmund.de>

	* deprecated.h (SCM_FALSEP, SCM_NFALSEP, SCM_BOOLP, SCM_BOOL):
	Reimplement using scm_is_false, scm_is_true, scm_is_bool, and
	scm_from_bool, respectively.
	(SCM_NINUMP): Added.
	
	* tags.h, deprecated.h (SCM_EQ_P): Deprecated by moving it into
	deprecated.h.  Replaced all uses with scm_is_eq.

2004-07-24  Kevin Ryde  <user42@zip.com.au>

	* threads.c, threads.h (scm_i_misc_mutex): New SCM_GLOBAL_MUTEX.
	* posix.c (scm_crypt): Use it to protect static data in crypt().

2004-07-23  Marius Vollmer  <marius.vollmer@uni-dortmund.de>

	* deprecated.h, deprecated.c, numbers.h (SCM_INUMP, SCM_NINUMP,
	SCM_INUM): Deprecated by renaming them to SCM_I_INUMP,
	SCM_I_NINUMP and SCM_I_INUM, respectively and adding deprecated
	versions to deprecated.h and deprecated.c.  Changed all uses to
	either use the SCM_I_ variants or scm_is_*, scm_to_*, or
	scm_from_*, as appropriate.

	* dynwind.c (scm_i_dowinds): Removed unused code that would call
	the unexisting scm_cross_dynwind_binding_scope for inums on the
	windlist.
	
2004-07-10  Marius Vollmer  <marius.vollmer@uni-dortmund.de>

	* socket.c (ipv6_net_to_num, scm_from_ipv6): Renamed
	ipv6_net_to_num to scm_from_ipv6, for converting from an IPv6
	byte-wise address to a SCM integer.  Changed all uses.
	(ipv6_num_to_net, scm_to_ipv6): Renamed ipv6_num_to_net to
	scm_to_ipv6 and added type and range checking, for converting from
	an IPv& byte-wise address to a SCM integer.  Changed all uses.
	(bignum_in_ipv6_range_p, VALIDATE_INET6): Removed, their function
	is now done by scm_to_ipv6.
	
	* numbers.c (scm_to_signed_integer, scm_to_unsigned_integer): dot
	not accept inexact integers.

	* validate.h, deprecated.h (SCM_VALIDATE_INUM,
	SCM_VALIDATE_INUM_COPY, SCM_VALIDATE_BIGINT,
	SCM_VALIDATE_INUM_MIN, SCM_VALIDATE_INUM_MIN_COPY,
	SCM_VALIDATE_INUM_MIN_DEF_COPY,SCM_VALIDATE_INUM_DEF,
	SCM_VALIDATE_INUM_DEF_COPY, SCM_VALIDATE_INUM_RANGE,
	SCM_VALIDATE_INUM_RANGE_COPY): Deprecated because they make the
	fixnum/bignum distinction visible.  Changed all uses to
	scm_to_size_t or similar.

2004-07-09  Marius Vollmer  <marius.vollmer@uni-dortmund.de>

	* cpp_cnvt.awk: Use scm_from_int instead of SCM_MAKINUM.

2004-07-10  Kevin Ryde  <user42@zip.com.au>

	* hash.c (scm_hashq, scm_hashv, scm_hash): Restrict to size>=1 rather
	than size>=0, since 0<=hash<size cannot be satisfied for size==0, and
	such a size causes divide-by-zeros in scm_hasher.

        * regex-posix.c (scm_make_regexp): Free rx on error, to avoid memory
	leak.

2004-07-08  Marius Vollmer  <marius.vollmer@uni-dortmund.de>

	* numbers.c (scm_is_signed_integer, scm_is_unsigned_integer):
	Rewritten using the same logic as scm_to_signed_integer and
	scm_to_unsigned_integer, respectively, which is better(tm).  Also,
	use CHAR_BIT instead of hardcoding 8.
	(LLONG_MIN, LLONG_MAX, ULLONG_MAX): Removed and used
	SCM_I_LLONG_MIN etc. instead.
	
	* numbers.h (SCM_MAKINUM, SCM_I_MAKINUM): Renamed SCM_MAKINUM to
	SCM_I_MAKINUM and changed all uses.
	* deprecated.h, deprecated.c (SCM_MAKINUM): Newly deprecated.

	* gen-scmconfig.c (SCM_I_LLONG_MIN, SCM_I_LLONG_MAX,
	SCM_I_ULLONG_MAX): Instead of hard-coding the numbers, compute
	them by assuming twos-complement.

2004-07-07  Marius Vollmer  <marius.vollmer@uni-dortmund.de>

	* gen-scmconfig.h.in: Added all the new SCM_I_GSC_*_LIMITS that
	configure now produces.
	* gen-scmconfig.c: Use them to output SCM_T_INT8_MIN, etc
	definitions, giving the limits of the integer types defined by
	Guile. Also, output a hard coded SCM_I_LLONG_MIN, etc since
	LLONG_MIN or LONG_LONG_MIN is hard to get at.

	* numbers.h (scm_to_short, scm_to_ushort): It's SHRT_MIN, etc, not
	SHORT_MIN.
	(scm_to_size_t): Use SIZE_MAX instead of cooking our own.
	(scm_to_long_long, scm_to_ulong_long, scm_to_int8, scm_to_uint8,
	scm_to_int16, scm_to_uint16, scm_to_int32, scm_to_uint32,
	scm_to_int64, scm_to_uint64, scm_to_intmax, scm_to_uintmax,
	scm_from_long_long, scm_from_ulong_long, scm_from_int8,
	scm_from_uint8, scm_from_int16, scm_from_uint16, scm_from_int32,
	scm_from_uint32, scm_from_int64, scm_from_uint64, scm_from_intmax,
	scm_from_uintmax): New.
	
2004-07-06  Marius Vollmer  <marius.vollmer@uni-dortmund.de>

	* tags.h (scm_is_eq): New.

	* deprecated.h, boolean.h (SCM_FALSEP, SCM_NFALSEP, SCM_BOOL,
	SCM_NEGATE_BOOL, SCM_BOOLP): Deprecated by moving into
	"deprecated.h".  Replaced all uses with scm_is_false, scm_is_true,
	scm_from_bool, and scm_is_bool, respectively.

	* boolean.h (scm_is_bool): Fix bug in prototype.
	(scm_from_bool): The argument is "x" not "f", stupid.

	* boolean.c (scm_is_bool): Fix typo.

	* numbers.h, numbers.c (scm_is_integer, scm_is_signed_integer,
	scm_is_unsigned_integer, scm_to_signed_integer,
	scm_to_unsigned_integer, scm_to_schar, scm_to_uchar, scm_to_char,
	scm_to_short, scm_to_ushort, scm_to_long, scm_to_ulong,
	scm_to_size_t, scm_to_ssize_t, scm_from_schar, scm_from_uchar,
	scm_from_char, scm_from_short, scm_from_ushort, scm_from_int,
	scm_from_uint, scm_from_long, scm_from_ulong, scm_from_size_t,
	scm_from_ssize_t, scm_is_real, scm_to_double, scm_from_double):
	New.
	
2004-07-05  Marius Vollmer  <marius.vollmer@uni-dortmund.de>

	* boolean.h, boolean.c (scm_is_true, scm_is_false, scm_from_bool,
	scm_to_bool): New.

2004-06-27  Dirk Herrmann  <dirk@dirk-herrmanns-seiten.de>

	* backtrace.c (display_expression, display_frame): Call
	scm_i_unmemoize_expr for unmemoizing a memoized object holding a
	single memoized expression.

	* debug.c (memoized_print): Don't try to unmemoize the memoized
	object, since we can't know whether it holds a single expression
	or a body.

	(scm_mem_to_proc): Removed check for lambda expression, since it
	was moot anyway.  Whoever uses these functions for debugging
	purposes should know what they do: Creating invalid memoized code
	will cause crashes, independent of whether this check is present
	or not.

	(scm_proc_to_mem): Take the closure's code as it is and don't
	append a SCM_IM_LAMBDA isym.  To allow easier debugging, the
	memoized code should not be modified.

	* debug.[ch] (scm_unmemoize, scm_i_unmemoize_expr): Removed
	scm_unmemoize from public use, but made scm_i_unmemoize_expr
	available as a guile internal function instead.  However,
	scm_i_unmemoize_expr will only work on memoized objects that hold
	a single memoized expression.  It won't work with bodies.

	* debug.c (scm_procedure_source), macros.c (macro_print), print.c
	(scm_iprin1): Call scm_i_unmemocopy_body for unmemoizing a body,
	i. e. a list of expressions.

	* eval.c (unmemoize_exprs): Drop internal body markers from the
	output during unmemoization.

	* eval.[ch] (scm_unmemocopy, scm_i_unmemocopy_expr,
	scm_i_unmemocopy_body): Removed scm_unmemocopy from public use,
	but made scm_i_unmemocopy_expr and scm_i_unmemocopy_body available
	as guile internal functions instead.  scm_i_unmemoize_expr will
	only work on a single memoized expression, while
	scm_i_unmemocopy_body will only work on bodies.

2004-06-21  Dirk Herrmann  <dirk@dirk-herrmanns-seiten.de>

	* eval.c (unmemoize_exprs): Handle semi-memoized code.

	(scm_cons_source, scm_primitive_eval): Prefer higher level
	predicate SCM_FALSEP over SCM_IMP.

2004-06-15  Rob Browning  <rlb@defaultvalue.org>

	* script.c (scm_shell_usage): minor phrasing change.

	* gc_os_dep.c: update ifdefery for macosx.
	(scm_get_stack_base): separate result initialization from
	declaration to slience warnings with macosx and hp-ux using gcc
	3.3.  Thanks to Andreas V�gele.

2004-06-13  Han-Wen Nienhuys   <hanwen@xs4all.nl>

	* eval.c (unmemoize_exprs): use SCM_CONSP for the loop condition.

2004-06-06  Dirk Herrmann  <dirk@dirk-herrmanns-seiten.de>

	* list.[ch] (scm_i_finite_list_copy): New internal function to
	copy lists that are known to be finite (though not necessarily
	proper).

	* debug.c (scm_procedure_source): Don't have scm_unmemocopy treat
	a closure's argument list like an expression of a body.

	* eval.c (unmemoize_expression, unmemoize_exprs, unmemoize_and,
	unmemoize_begin, unmemoize_case, unmemoize_cond, unmemoize_delay,
	unmemoize_do, unmemoize_if, unmemoize_lambda, unmemoize_let,
	unmemoize_letrec, unmemoize_letstar, unmemoize_or,
	unmemoize_set_x, unmemoize_apply, unmemoize_atcall_cc,
	unmemoize_at_call_with_values, unmemoize_future, sym_atslot_ref, 
	unmemoize_atslot_ref, sym_atslot_set_x, unmemoize_atslot_set_x,
	unmemoize_builtin_macro): New static functions and symbols.

	(scm_unmemocopy): Rewritten in terms of the above.  scm_unmemocopy
	now has a slightly different meaning: The memoized form that is
	receives as its argument is now interpreted as a sequence of
	expressions from a body.

	(unmemocar, scm_unmemocar): Since the whole functionality of
	unmemocar and scm_unmemocar is not needed any more, scm_unmemocar
	has its old content back and is deprecated, while unmemocar has
	been removed.

	(SCM_BIT7): Removed.

	(CEVAL): For unmemoizing a single expression, call
	unmemoize_expression instead of scm_unmemocopy, which now expects
	a sequence of body expressions.  Eliminated unnecessary empty
	environment frame when executing let* forms.  Eliminated
	unmemoization step from evaluator.

2004-06-02  Marius Vollmer  <marius.vollmer@uni-dortmund.de>

	* eval.c (scm_macroexp, macroexp): Renamed scm_macroexp to
	macroexp and made static.  Added new version of scm_macroexp that
	emits a deprecation warning and then calls macroexp.
	(scm_m_undefine): Issue deprecation warning.
	
2004-05-30  Dirk Herrmann  <dirk@dirk-herrmanns-seiten.de>

	* eval.c (lookup_global_symbol, literal_p, try_macro_lookup):
	Modified to make set! work on symbols that represent syntactic
	keywords.

2004-05-26  Han-Wen Nienhuys   <hanwen@xs4all.nl>

	* gc.h (SCM_CELL_OBJECT_LOC): use SCM_GC_CELL_OBJECT to prevent
	compound expression as lvalue errors.

2004-05-24  Marius Vollmer  <mvo@zagadka.de>

	* dynwind.c (winder_mark): Use SCM_PACK to correctly convert the
	WINDER_DATA to a SCM.

2004-05-24  Dirk Herrmann  <dirk@dirk-herrmanns-seiten.de>

	* goops.c (compute_getters_n_setters, create_standard_classes,
	scm_add_slot): Compute closures by calling scm_i_eval_x on a
	lambda expression rather than creating them with scm_closure.

2004-05-22  Dirk Herrmann  <dirk@dirk-herrmanns-seiten.de>

	* eval.c (s_macro_keyword, scm_m_set_x): Remove checking for
	misplaced syntactic keywords.  This will not work unless guile's
	defmacro feature is deprecated.

	(scm_m_case): Fixed a bug that caused the list of labels to grow
	with every case form.

2004-05-19  Kevin Ryde  <user42@zip.com.au>

	* numbers.c (scm_round_number): For inum and big, just return x.  For
	real, use scm_round for 2^54-1 etc problems covered there.

	* numbers.c (trunc): Remove #define to scm_truncate when the C library
	doesn't provide trunc.  This was for when `truncate' was done as a
	scm_tc7_dsubr, no longer required.

	* threads.c (scm_threads_mark_stacks) [SCM_STACK_GROWS_UP]: Correction
	to stack marking call, two parameters and no cast on t->base.

2004-05-18  Marius Vollmer  <mvo@zagadka.de>

	* hashtab.c (rehash_after_gc): Bug fix: properly link the
	processed hashtables back into the weak_hashtables list.  Thanks
	to Bill Schottstaedt!

2004-05-16  Dirk Herrmann  <dirk@dirk-herrmanns-seiten.de>

	* eval.c (unmemoize_quote): New static function.

	(scm_m_quote, scm_m_atslot_ref, SCM_CEVAL): Changed the byte code
	representation of 'quote' and '@slot-ref' to an improper list.
	This reduces execution time, the number of cells used to hold the
	memoized code, and thus also reduces garbage collection time.

	(scm_unmemocopy): Use unmemoize_quote for quote expressions.

	(SCM_CEVAL): Changed macro handling to also work with macros that
	return improper lists.  Added an assertion, that the code returned
	by a macro transformer will not lead to cycles in the memoized
	code.

2004-05-15  Dirk Herrmann  <dirk@dirk-herrmanns-seiten.de>

	No functional change, just rearrangements of functions within the
	file.

	* eval.c (scm_ilookup, scm_unbound_variable_key,
	error_unbound_variable, scm_lookupcar1, scm_lookupcar): Moved to
	the definitions used for execution, since that's where they will
	belong to later.

2004-05-15  Dirk Herrmann  <dirk@dirk-herrmanns-seiten.de>

	* numbers.h (SCM_SLOPPY_FRACTIONP): Removed.  It was not used
	throughout guile, has not been part of an official release yet,
	and the concept of sloppy predicates has never been a good idea.

	(SCM_FRACTION_NUMERATOR, SCM_FRACTION_DENOMINATOR,
	SCM_FRACTION_SET_NUMERATOR, SCM_FRACTION_SET_DENOMINATOR):
	Simplified.

2004-05-15  Dirk Herrmann  <dirk@dirk-herrmanns-seiten.de>

	* throw.c (SETJBJMPBUF, SCM_SETJBDFRAME): Add cast to scm_t_bits
	to make explicit what happens.

2004-05-15  Dirk Herrmann  <dirk@dirk-herrmanns-seiten.de>

	* dynl.c (SET_DYNL_HANDLE): Add cast to scm_t_bits to make
	explicit what happens.

	* guardians.c (TCONC_IN): Use SCM_SET_CELL_OBJECT_x rather than
	SCM_SET_CELL_WORD_x when writing scheme objets to cell elements.

2004-05-11  Marius Vollmer  <mvo@zagadka.de>

	* scmsigs.c (scm_sigaction_for_thread): Validate that the handler
	is indeed a procedure when it isn't a number.

2004-05-10  Marius Vollmer  <mvo@zagadka.de>

	Convert floating point numbers into strings with an arbitrary
	radix.  Thanks to Richard Todd!
	
	* numbers.c (FLOBUFLEN): Increase so that radix 2 strings will
	fit.
	(fx): Removed.
	(scm_dblprec, fx_per_radix, init_dblprec, init_fx_radix,
	number_chars): New, to support variable radices.
	(idbl2str): Use above instead of the old base-10 only tables.
	(iflo2str): Pass on new RADIX argument to idbl2str.
	(scm_number_to_string): Pass radix to iflo2str.
	(scm_print_real, scm_print_complex): Explicitly pass radix 10 to
	iflo2str.
	(scm_init_numbers): Call init_dblprec and init_fx_radix for all
	possible radices.

2004-05-10  Kevin Ryde  <user42@zip.com.au>

	* numbers.c (scm_logbit_p): Correction to test above the end of an
	inum.  Reported by Jan Konecny.

2004-05-06  Marius Vollmer  <marius.vollmer@uni-dortmund.de>

	* gc.h (scm_t_cell): Fields are now of type SCM instead of
	scm_t_bits.  Updated all users.
	(SCM_GC_CARD_SIZE_MASK): Use SCM_GC_SIZEOF_CARD instead of
	duplicating the code.
	(SCM_CELL_OBJECT_LOC): New.
	(SCM_CARLOC, SCM_CDRLOC): Use it instead of SCM_CELL_WORD_LOC.
	(SCM_CELL_WORD_LOC): Moved to "deprecated.h".

	* smob.h (SCM_SMOB_DATA_2, SCM_SMOB_DATA_3, SCM_SMOB_FLAGS,
	SCM_SET_SMOB_DATA_2, SCM_SET_SMOB_DATA_3, SCM_SET_SMOB_FLAGS,
	SCM_SMOB_OBJECT, SCM_SMOB_OBJECT_2, SCM_SMOB_OBJECT_3,
	SCM_SET_SMOB_OBJECT, SCM_SET_SMOB_OBJECT_2, SCM_SET_SMOB_OBJECT_3,
	SCM_SMOB_OBJECT_LOC, SCM_SMOB_OBJECT_2_LOC,
	SCM_SMOB_OBJECT_3_LOC): New.
	* smob.c (scm_i_set_smob_flags): New function.

	* dynl.c, dynwind.c, eval.h, fluids.h, futures.h, hashtab.h,
	hooks.h, keywords.h, macros.h, macros.c, mallocs.c, mallocs.h,
	random.h, regex-posix.h, root.h, srcprop.h, srcprop.c, threads.h:
	Use SCM_SMOB_* instead of SCM_CELL_* as appropriate.  Use
	SCM_SMOB_FLAGS and SCM_SET_SMOB_FLAGS instead of accessing the
	zeroth word directly.  Use SCM_SMOB_PREDICATE as appropriate.

	* numbers.h (SCM_I_BIG_MPZ): Use SCM_CELL_OBJECT_LOC instead of
	taking the address of SCM_CELL_WORD_1, the latter being no longer
	an lvalue.

	* variable.h (SCM_VARIABLE_LOC): Use SCM_CELL_OBJECT_LOC instead
	of casting SCM_CELL_WORD_LOC.

2004-05-02  Kevin Ryde  <user42@zip.com.au>

	* eval.c (scm_macroexp): Add prototype, since it's not in eval.h under
	--disable-deprecated.  Reported by Andreas V�gele.

	* filesys.c (_POSIX_C_SOURCE): Define to 199506L to get readdir_r (in
	particular on HP-UX).  Reported by Andreas V�gele.

	* list.c (varargs.h): Remove, leave just stdarg.h which is all the
	code has support for.  Fixes building with AIX cc, which is ansi but
	doesn't define __STDC__.  Reported by Keith Crane.
	(var_start): Remove macro, this variation no longer required.
	(scm_list_n): Use va_start directly.

2004-05-01  Kevin Ryde  <user42@zip.com.au>

	* continuations.c (scm_dynthrow): Use >= instead of SCM_PTR_GE which
	is now gone.  Reported by Andreas V�gele.

2004-04-28  Kevin Ryde  <user42@zip.com.au>

	* backtrace.c (display_frame_expr), numbers.c (XDIGIT2UINT,
	mem2uinteger, mem2decimal_from_point, mem2ureal): Cast char to int for
	ctype.h tests, to avoid warnings from gcc on HP-UX about char as array
	subscript.  Reported by Andreas V�gele.
	Also cast through unsigned char to avoid passing negatives to those
	macros if input contains 8-bit values.

	* num2integral.i.c (NUM2INTEGRAL): Under non-BIGMPZ_FITSP case,
	corrections to range check for signed numbers.  Remove
	scm_remember_upto_here_1(num) from these checks, since num is used
	subsequently anyway.

	* num2integral.i.c (NUM2INTEGRAL): Test BIGMPZ_FITSP with "!= 0" to
	avoid warning from gcc 3.4.  Reported by Hyperdivision.
	
	* numbers.c (scm_bit_extract): Use min instead of MIN.
	(MIN): Remove, this conflicts with similar macro defined by limits.h
	on HP-UX.  Reported by Andreas V�gele.

	* stime.c (_POSIX_C_SOURCE): Define to 199506L to get gmtime_r (in
	particular on HP-UX).  Reported by Andreas V�gele.

	* threads.c (scm_threads_mark_stacks): Correction sizet -> size_t.
	Reported by Andreas V�gele.

	* threads-plugin.h (SCM_MUTEX_MAXSIZE): Increase to 25*sizeof(long),
	for the benefit of hpux11 where pthread_mutex_t is 88 bytes.  Reported
	by Andreas V�gele.

2004-04-22  Dirk Herrmann  <dirk@dirk-herrmanns-seiten.de>

	* eval.c (s_macro_keyword): New static identifier.

	(scm_m_define): Change order to first create binding and
	evaluating the expression afterwards.

	(scm_m_set_x): Memoize complete set! expression.  Only leave
	symbols if no binding exists at memoization time.  Throw error if
	assigning to a syntactic keyword.

	(lazy_memoize_variable): New function.

	(CEVAL): When execution set!, perform lazy memoization if
	unmemoized symbol is detected.

	* modules.c (module_variable): Return variables with unbound
	value.

	* tags.h: Fix comment.

2004-04-25  Kevin Ryde  <user42@zip.com.au>

	* chars.c (scm_char_upcase, scm_char_downcase, scm_c_upcase,
	scm_c_downcase): Use ctype.h toupper and tolower.  This will be useful
	in 8-bit locales, and ensures consistency with char-upper-case? and
	char-lower-case? which already use ctype.h.
	(scm_c_upcase_table, scm_c_downcase_table, scm_lowers, scm_uppers):
	Remove.
	* chars.c, chars.h, init.c (scm_tables_prehistory): Remove.

	* socket.c (VALIDATE_INET6): Correction to bignum_in_ipv6_range_p
	call.  Reported by Hyperdivision.

	* threads.c (scm_yield): Correction, actually call scm_thread_yield.
	Reported by Hyperdivision.

	* unif.c (s_scm_make_uve): Remove unused local variable.  Reported by
	Hyperdivision.

2004-04-22  Dirk Herrmann  <dirk@dirk-herrmanns-seiten.de>

	Hide the implementation of ilocs and isyms in eval.c.

	* deprecated.h (SCM_IFRINC, SCM_ICDR, SCM_IFRAME, SCM_IDIST,
	SCM_ICDRP), eval.c (SCM_IFRINC, SCM_ICDR, SCM_IFRAME, SCM_IDIST,
	SCM_ICDRP), eval.h (SCM_ICDR, SCM_IFRINC, SCM_IFRAME, SCM_IDIST,
	SCM_ICDRP): Deprecated and added to deprecated.h.  Moved from
	eval.h to eval.c.

	* deprecated.c (scm_isymnames), deprecated.h (scm_isymnames,
	SCM_ISYMNUM, SCM_ISYMCHARS), eval.c (SCM_ISYMNUM, isymnames,
	scm_unmemocopy, CEVAL), print.c (scm_isymnames), tags.h
	(SCM_ISYMNUM, scm_isymnames, SCM_ISYMCHARS): Deprecated
	scm_isymnames, SCM_ISYMNUM and SCM_ISYMCHARS and added to
	deprecated.[hc].  Moved scm_isymnames from print.c to eval.c and
	renamed to isymnames.  Moved SCM_ISYMNUM from tags.h to eval.c and
	renamed to ISYMNUM.

	* eval.c (scm_i_print_iloc, scm_i_print_isym), eval.h
	(scm_i_print_iloc, scm_i_print_isym), print.c (scm_iprin1):
	Extracted printing of ilocs and isyms to guile internal functions
	scm_i_print_iloc, scm_i_print_isym of eval.c.

2004-04-22  Kevin Ryde  <user42@zip.com.au>

	* numbers.c (scm_bit_extract): Use SCM_SRS for signed right shift.

	* numbers.c (scm_round): Test for x already an integer, to avoid bad
	rounding in x+0.5 when x is a big value already an integer.  In
	certain hardware rounding cases x+0.5 can give an adjacent integer,
	leading to that as the result, when we really just wanted x itself.
	
2004-04-19  Dirk Herrmann  <dirk@dirk-herrmanns-seiten.de>

	* eval.c (scm_unmemocopy): Fixed unmemoization of let*.

	(deval_args, CEVAL): Minor improvements: Reduced variable scopes,
	added const qualifiers, cast intentionally unused expressions to
	void for emphasis, improved comment.

2004-04-18  Dirk Herrmann  <dirk@dirk-herrmanns-seiten.de>

	* tags.h (scm_tags, scm_tc8_tags, scm_tc9_flag, scm_tc8_flag,
	scm_tc8_isym): Renamed scm_tags to scm_tc8_tags.  Renamed
	scm_tc9_flag to scm_tc8_flag.  Introduced new identifier
	scm_tc8_isym.  Defined tc8-tags relative to scm_tc3_imm24.
	Defined the tc8-tag for flags to be 0x04, which will mean that
	SCM_BOOL_F will also have the value 0x04 instead of 0x013c.  Due
	to the reduced number of bits and the simpler bit pattern for
	SCM_BOOL_F, certain machines may be able to use more efficient
	processor instructions to deal with SCM_BOOL_F.

	(SCM_ITAG9, SCM_MAKE_ITAG9, SCM_ITAG9_DATA): Removed.  These have
	never been defined in a released version, thus no need to
	deprecate them.

	(SCM_IFLAGP, SCM_MAKIFLAG, SCM_IFLAGNUM): Flags now use tc8
	instead of tc9 tags.

	(SCM_ISYMP, SCM_MAKISYM, SCM_ISYMNUM): Isyms now use tc8 instead
	of tc9 tags.

	(SCM_MAKSPCSYM): Removed.  It is almost impossible that user code
	could have used this definition.

	(SCM_IM_AND, SCM_IM_BEGIN, SCM_IM_CASE, SCM_IM_COND, SCM_IM_DO,
	SCM_IM_IF, SCM_IM_LAMBDA, SCM_IM_LET, SCM_IM_LETSTAR,
	SCM_IM_LETREC, SCM_IM_OR, SCM_IM_QUOTE, SCM_IM_SET_X): Now encoded
	as isyms, as special isyms don't exist any more.

2004-04-18  Kevin Ryde  <user42@zip.com.au>

	* filesys.c (scm_readdir): Use readdir_r when available, for thread
	safety.

	* numbers.c (scm_max, scm_min): For big/real, use SCM_SWAP rather than
	explicit swapping code.

2004-04-15  Kevin Ryde  <user42@zip.com.au>

	* cpp_sig_symbols.in: Add SIGSYS.
	
	* list.c (scm_append_x): Use iterative style, to avoid non-tail
	recursion.

	* numbers.c (scm_max, scm_min): For inum/frac, frac/inum, big/frac,
	frac/big and frac/frac, use scm_less_p for exact comparison.

	* numbers.c (scm_gcd): For inum/big, use mpz_gcd_ui by sharing code
	with big/inum.

	* numbers.c (xisinf): Add a comment about solaris 7 lacking isinf.

2004-04-06  Han-Wen Nienhuys   <hanwen@xs4all.nl>

	* inline.h (scm_cell): use SCM_GC_CELL_WORD for checking tag.

	* chars.h (scm_init_chars): change scm_{upcase,downcase} to
	scm_c_{up,down}case. 
	(SCM_MAKE_CHAR): add (unsigned char) cast. This prevents havoc
	when hi-bit ASCII is subjected to SCM_MAKE_CHAR().  

2004-04-06  Kevin Ryde  <user42@zip.com.au>

	* numbers.c (scm_ash): Remove stray "}" in docstring.

	* numbers.c (scm_make_ratio): For inum/bignum integer detection, use
	x==SCM_MOST_NEGATIVE_FIXNUM explicitly, for clarity and to avoid
	calling mpz_cmp_ui in most cases.

	* numbers.c (scm_quotient, scm_remainder): In inum/big, use mpz_cmp_ui
	for big == abs(most-negative-fixnum) special case.
	(abs_most_negative_fixnum): Remove, no longer used.

	* scmsigs.c (scm_sigaction_for_thread): Correction to signum range
	test, avoids SCM_VECTOR_REF outside bounds of signal_handlers on
	calling (sigaction NSIG).

	* simpos.c (scm_system_star): Fix execargv memory leak, merge parent
	and fork error cases to do this.

2004-04-03  Dirk Herrmann  <dirk@dirk-herrmanns-seiten.de>

	* eval.c (CEVAL): Don't distinguish between short and long
	instructions when dispatching - just always dispatch on the
	instruction code, which is common for short and long instructions.
	Further, removed unnecessary goto statements and added comment.

2004-04-03  Dirk Herrmann  <dirk@dirk-herrmanns-seiten.de>

	* eval.c (scm_unmemocopy): Don't distinguish between short and
	long instructions when dispatching - just always dispatch on the
	instruction code, which is common for short and long instructions.
	Further, removed unnecessary goto statements, fixed indentation
	and replaced SCM_IMP predicates by SCM_NULLP.

2004-04-03  Dirk Herrmann  <dirk@dirk-herrmanns-seiten.de>

	* eval.c (scm_lookupcar1, CEVAL): Use SCM_ILOCP instead of
	comparison with SCM_ILOC00.  In CEVAL, eliminate goto-label
	'checkmacro'.

2004-03-31  Kevin Ryde  <user42@zip.com.au>

	* simpos.c: Include <signal.h> for SIG_IGN and friends.

2004-03-29  Dirk Herrmann  <dirk@dirk-herrmanns-seiten.de>

	Introduce scm_debug_mode_p as a replacement for scm_debug_mode and
	SCM_DEBUGGINGP:

	* debug.h (scm_debug_mode_p, scm_debug_mode, SCM_DEBUGGINGP),
	eval.c (scm_debug_mode_p): Deprecated scm_debug_mode and
	SCM_DEBUGGINGP.  Provided scm_debug_mode_p instead, to have one
	single interface that also matches the naming conventions.
	Probably scm_debug_mode_p should be part of the private interface
	anyway.

	* debug.h (scm_debug_mode_p), backtrace.c (display_error_body),
	eval.c (SCM_APPLY, scm_trampoline_0, scm_trampoline_1,
	scm_trampoline_2): Change uses of scm_debug_mode or SCM_DEBUGGINGP
	to scm_debug_mode_p.


	Deprecate direct access to scm_ceval, scm_deval and scm_ceval_ptr:

	* eval.h (scm_ceval, scm_deval, scm_ceval_ptr), debug.h
	(scm_ceval_ptr): Deprecated.  Moved declaration of scm_ceval_ptr
	from debug.h to eval.h.

	* debug.h (SCM_RESET_DEBUG_MODE): Don't access scm_ceval_ptr any
	more, just leave it with setting scm_debug_mode_p, which is
	equivalent for practical purposes.

	* deprecated.h (SCM_XEVAL, SCM_XEVALCAR): Call scm_i_eval_x
	instead of *scm_ceval_ptr.  Leave all evaluating to scm_i_eval_x.

	* gdbint.c (gdb_eval): Call scm_i_eval_x instead of scm_ceval.

	* eval.c (ceval, deval, scm_ceval, scm_deval): Made scm_ceval
	static and renamed it to ceval throughout.  Provide a new exported
	but deprecated function scm_ceval as a wrapper for backwards
	compatibility.  The same is done for the deval/scm_deval pair of
	functions.

	* eval.c (CEVAL, SCM_CEVAL): Renamed SCM_CEVAL to CEVAL
	throughout.  Defined CEVAL to ceval or deval, based on compilation
	phase.

	* eval.c (SCM_XEVAL, SCM_XEVALCAR): Dispatch on scm_debug_mode_p
	to ceval and deval instead of calling *scm_ceval_ptr.

	* eval.c (dispatching_eval): New deprecated static function.

	* eval.c (scm_ceval_ptr): Initialized to dispatching_eval in order
	to emulate its old behaviour as closely as possible.


	Change the evaluator such that only expressions for which pair? is
	true are passed to CEVAL, and such that all other expressions are
	evaluated outside of CEVAL:

	* eval.c (EVAL): New, provided in analogy to EVALCAR.  Evaluate an
	expression that is assumed to be memoized already.  All but
	expressions of the form '(<form> <form> ...)' are evaluated inline
	without calling an evaluator.

	* eval.c (SCM_XEVAL, SCM_XEVALCAR, EVALCAR): Evaluate all but
	expressions of the form '(<form> <form> ...)' inline without
	calling an evaluator.

	* eval.c (scm_i_eval_x, scm_i_eval, scm_ceval, scm_deval): Handle
	the special case of unmemoized symbols passed on the top level.

	* eval.c (CEVAL): Change calls to CEVAL to EVAL, except where it
	is known that the expression passed to CEVAL is of the form
	'(<form> <form> ...)'.  Remove handling of the tc7-objects, since
	now it is known that the input expression of CEVAL is a pair.

2004-03-29  Dirk Herrmann  <dirk@dirk-herrmanns-seiten.de>

	* eval.c (is_self_quoting_p): New static function.

	(scm_m_quote): Use is_self_quoting_p.

	(copy_tree): Corrected typo in comment.

2004-03-28  Han-Wen Nienhuys   <hanwen@xs4all.nl>

	* eval.c (s_scm_copy_tree): idem.

	* list.c (s_scm_filter): remove "pointer" from doc string.

	* gc.h (SCM_GC_CELL_TYPE): SCM_GC_CELL_TYPE uses SCM_GC_CELL_OBJECT.

	* goops.h (SCM_NUMBER_OF_SLOTS): don't SCM_UNPACK the result.

	* backtrace.c ("display_backtrace_body"): SCM_PACK before SCM_EQ_P
	(display_frame): idem.
	(display_backtrace_file_and_line): idem.

	* tags.h (SCM_UNPACK): stricter typechecking on SCM_UNPACK
	arguments.

2004-03-26  Kevin Ryde  <user42@zip.com.au>

	* filesys.c (scm_getcwd, scm_readlink): Avoid memory leak on errors.

	* numbers.c (scm_modulo): For inum/big and big/big, remove test of
	big==0 since that never occurs.

	* numbers.c, numbers.h (scm_modulo_expt): Renamed from
	scm_modular_expt, matching scheme level name `modulo-expt'.

	* numbers.c (scm_modular_expt): Return a negative remainder for a
	negative divisor, the same as `modulo' does.

2004-03-26  Eric Hanchrow <offby1@blarg.net>

	* numbers.c, numbers.h (scm_modular_expt): New function.

2004-03-25  Kevin Ryde  <user42@zip.com.au>

	* numbers.c (scm_min, scm_max): Correction to big/real and real/big,
	return inexact as required by r5rs.

2004-03-24  Dirk Herrmann  <dirk@dirk-herrmanns-seiten.de>

	* eval.c: Separated some definitions relevant for execution from
	the memoization part of the file.

	(copy_tree): New static function

	(scm_copy_tree): Rewritten to fix two kinds or bugs: First, cyclic
	structures are detected now and will lead to an exception instead
	of forcing guile to run in an endless loop, using up all the
	system's memory.  Second, arrays in the cdr of an improper list
	are now copied.  See the new test cases in eval.test.

2004-03-24  Dirk Herrmann  <dirk@dirk-herrmanns-seiten.de>

	* posix.c (scm_gethostname): Make sure len is initialised before
	it is used.  Restructured to (hopefully) represent possible
	configurations more clearly in the code.  Added unwind handler.

2004-03-23  Kevin Ryde  <user42@zip.com.au>

	* posix.c (scm_gethostname): Use sysconf(_SC_HOST_NAME_MAX) and/or
	MAXHOSTNAMELEN when available.

2004-03-21  Marius Vollmer  <mvo@zagadka.de>

	* read.c (skip_scsh_block_comment): Also recognize '\r' as a line
	terminator.  Rewritten the logic as a state machine, I must have
	been doing too much VHDL lately...

	* eval.c (scm_ceval, scm_deval): Explicitely evaluate ports to
	themselves.  Thanks to Han-Wen Nienhuys!

	* list.c: Changed docstrings so that they no longer talk about
	returning 'pointers' to something.

2004-03-20  Han-Wen Nienhuys   <hanwen@xs4all.nl>

	* gc.c: remove set_debug_cell_accesses! when
	SCM_DEBUG_CELL_ACCESSES is not defined. Scheme source code should
	use (if (defined? 'set-debug-cell-accesses!) .. ) to switch on
	debugging conditionally.
 
2004-03-21  Kevin Ryde  <user42@zip.com.au>

	* stime.c (scm_gmtime): Use gmtime_r when available, for thread safety.

2004-03-20  Kevin Ryde  <user42@zip.com.au>

	* posix.c (scm_gethostname): Preserve errno across free() call.

2004-03-18  Han-Wen Nienhuys   <hanwen@xs4all.nl>

	* gc-card.c (sweep_card): use SCM_GC_SET_CELL_WORD for setting
	free cells.

2004-03-14  Kevin Ryde  <user42@zip.com.au>

	* stime.c: Define _GNU_SOURCE for strptime prototype from glibc.
	(strptime): Use	HAVE_DECL_STRPTIME for when to give own prototype.

2004-03-07  Kevin Ryde  <user42@zip.com.au>

	* stime.c (scm_gmtime): Return bd_time->tm_zone when available, rather
	than "GMT" always.
	(filltime): Make zname parameter "const".

2004-03-03  Mikael Djurfeldt  <mdj@chunk.mit.edu>

	* threads.c, threads.h (scm_c_scm2thread): New function.

2004-02-29  Kevin Ryde  <user42@zip.com.au>

	* numbers.c (guile_ieee_init): Use C99 INFINITY and NAN when
	available.  Test HAVE_DINFINITY and HAVE_DQNAN for those globals, in
	particular don't assume "defined (__alpha__) && ! defined (linux)"
	means OSF.  Remove "SCO" code, which was not really SCO specific and
	which John W. Eaton advises should be long past being needed.

	* posix.c (scm_execl, scm_execlp, scm_execle): Avoid memory leak under
	error throw.

2004-02-24  Kevin Ryde  <user42@zip.com.au>

	* posix.c (scm_cuserid): Use a private result buffer, for thread safe.

2004-02-22  Kevin Ryde  <user42@zip.com.au>

	* numbers.c (scm_max, scm_min): For one arg, dispatch to generic for
	complex, same as for two args.  (Handle only inum, big, real, frac).

2004-02-21  Kevin Ryde  <user42@zip.com.au>

	* posix.c (scm_crypt): Use new HAVE_CRYPT.
	(<crypt.h>): Remove HAVE_LIBCRYPT condition.
	Reported by Andreas Voegele.

2004-02-20  Neil Jerram  <neil@ossau.uklinux.net>

	* list.c (scm_list_n): Add #if SCM_DEBUG_CELL_ACCESSES_P around
	validation.

	* read.c (scm_lreadparen): Removed.
	(scm_lreadparen1): Renamed scm_i_lreadparen.

2004-02-20  Han-Wen Nienhuys   <hanwen@xs4all.nl>

	* list.c (scm_list_n): validate non-immediate arguments;
	this will catch forgotten a SCM_UNDEFINED.

2004-02-18  Marius Vollmer  <mvo@zagadka.de>

	* gc.h (scm_gc_cells_collected): Removed duplicated declaration.
	Thanks to Bill Schottstaedt!
	
	* socket.h (scm_gethost): Removed prototype it is already in
	"net_db.h".  Thanks to Bill Schottstaedt!
	
2004-02-18  Kevin Ryde  <user42@zip.com.au>

	* num2integral.i.c (INTEGRAL2BIG): WORDS_BIGENDIAN not right for word
	order parameter to mpz_import, in fact with just one word there's no
	order to worry about at all.

	* numbers.c (scm_num_eq_p): For real==frac, complex==frac, frac==real
	and frac==complex, make an exact comparison rather than converting
	with fraction2double.

	* posix.c, putenv.c, stime.c (environ): Use _NSGetEnviron in Darwin
	shared library, since environ is not directly available there.

	* script.c (scm_shell_usage): Print to stdout for --help, per GNU
	standard.

	* stime.c (scm_localtime, scm_gmtime, scm_mktime): Provide a default
	errno EINVAL in case localtime and gmtime don't set it.
	(scm_mktime, scm_strptime): Forcibly use errno EINVAL for our
	SCM_SYSERROR, since mktime and strptime generally don't set errno.

2004-02-16  Kevin Ryde  <kevin@swox.se>

	* gc-malloc.c (scm_done_malloc, scm_done_free): Allow negative sizes,
	which were permitted in the past for these.

	* num2float.i.c (NUM2FLOAT): Expand isfinite to !xisinf, as per
	previous change to numbers.c.

	* script.c (scm_shell_usage): Print bug-guile email address, as per
	GNU standard.  Reported by Han-Wen Nienhuys.

2004-02-13  Mikael Djurfeldt  <djurfeldt@nada.kth.se>

	* unif.c (scm_make_uve): Removed local variable and simplified
	code in order to avoid compiler used uninitialized warnings.

	* hashtab.c, hashtab.h (scm_hash_map_to_list): Renamed from
	scm_hash_map.
	(scm_hash_fold): Use scm_call_3 directly in the call to
	scm_internal_hash_fold instead of going via fold_proc (which is
	now removed).
	(scm_hash_for_each): Use a trampoline +
	scm_internal_hash_for_each_handle.
	(scm_internal_hash_for_each_handle, scm_hash_for_each_handle): New
	functions.

2004-02-12  Kevin Ryde  <user42@zip.com.au>

	* ports.c (scm_port_line): In docstring, note first line is 0.
	(scm_set_port_line_x): In docstring, note first line is 0.
	(scm_port_column): In docstring, there's no default to current input
	port, and remove shared port-line @defun.
	(scm_set_port_column_x): In docstring, there's no default to current
	input port, note first column is 0, remove shared set-port-line!
	@defun.

	* ramap.c (scm_array_fill_x): For fvect and dvect, use scm_num2dbl to
	convert args the same way that array-set! does.

	* unif.c (scm_make_uve, scm_array_p): Allow fraction 1/3 as prototype
	for dvect.
	(scm_array_p): Add missing "break"s in switch, fix llvect test look
	for "l" not "s", fix dvect to be false for singp(prot) since such a
	value is for fvect.
	(scm_array_prototype): Return 1/3 for dvect, rather than 0.33..33.
	(exactly_one_third): New variable.
	(scm_init_unif): Initialize it.

2004-02-10  Neil Jerram  <neil@ossau.uklinux.net>

	* read.c (scm_read_opts): Change `escaped-parens' to

2004-02-08  Neil Jerram  <neil@ossau.uklinux.net>

	* read.c (scm_read_opts): New opts `elisp-vectors' and
	`escaped-parens'.
	(s_vector): New.
	(scm_lreadr): Use scm_lreadparen1 instead of scm_lreadparen.  Make
	handling of elisp vector syntax dependent on SCM_ENABLE_ELISP and
	`elisp-vectors' option instead of SCM_ELISP_READ_EXTENSIONS.
	Allow "\(" and "\)" in strings when SCM_ENABLE_ELISP defined and
	`escaped-parens' option set.
	(scm_read_token): If elisp vector syntax active, disallow [ and ]
	in tokens.
	(scm_lreadparen): Rewrite as interface to scm_lreadparen1.
	(scm_lreadparen1): New.

	* read.h: Remove conditionally compiled last arg to
	scm_lreadparen.
	(SCM_ELISP_VECTORS_P, SCM_ESCAPED_PARENS_P): New.
	
2004-01-23  Han-Wen Nienhuys   <hanwen@xs4all.nl>

	* eval.c (m_expand_body): remove stray variable new_body.

2004-01-22  Marius Vollmer  <mvo@zagadka.de>

	* eval.c (m_expand_body): Rewrite the expression in place (by
	overwriting FORMS) also when a letrec is constructed, not only
	when no definitions are found.  Do not return rewritten expression
	to emphasize the in-place rewriting.  Changed all users.

2004-01-19  Han-Wen Nienhuys   <hanwen@xs4all.nl>

	* gc.c: add protected_object_count, a number that is dumped from
	gc_stats()

2004-01-11  Marius Vollmer  <mvo@zagadka.de>

	* dynwind.h, dynwind.c (scm_frame_unwind,
	scm_frame_unwind_handler): Renamed and changed all uses.
	(scm_frame_rewind, scm_frame_rewind_handler): Likewise.
	
2004-01-11  Kevin Ryde  <user42@zip.com.au>

	* unif.c (scm_bit_count, scm_bit_position, s_scm_bit_set_star_x,
	s_scm_bit_count_star, s_scm_bit_invert_x): Clarify docstrings, as per
	changes made to scheme-compound.texi.

2004-01-10  Marius Vollmer  <mvo@zagadka.de>

 	* print.c (scm_print_symbol_name): Handle #{`foo}#, #{,foo}#,
	#{.}#, and all numeric strings specially.  Thanks to Paul Jarc!

	* guile-snarf.in: Use mkdir to create a unique temporary directory
	that we can safely use.  Thanks to Stefan Nordhausen!

2004-01-07  Marius Vollmer  <marius.vollmer@uni-dortmund.de>

	* dynwind.h, dynwind.c (scm_i_dowinds): Removed 'explicit'
	argument since it is always zero now.  Changed all callers.
	Removed code for handling fluids.

	* fluids.c (scm_c_with_fluids): Use frames instead of adding to
	the wind chain explicitely.  Use scm_c_with_fluid for the common
	case of only one fluid.
	(scm_with_fluid): New.
	(scm_c_with_fluid): Use frames instead of scm_c_with_fluids.
	
	* fluids.h, fluids.c (scm_frame_fluid): New.
	(scm_with_fluid): New.
	(scm_i_swap_fluids, scm_i_swap_fluids_reverse): Removed.

	* dynwind.c (scm_frame_end): Do not use scm_i_dowinds.  Instead,
	do the unwinding directly.  It is simple enough.
	
	* dynwind.h, dynwind.c: Did the following renamings:
	scm_begin_frame -> scm_frame_begin,

	Reported by Richard Todd.

	* threads-plugin.h (SCM_MUTEX_MAXSIZE): Increase to 12*sizeof(long),
	for the benefit of powerpc-apple-darwin5.5.  Reported by Richard Todd.

	* unif.c (scm_aind): Test SCM_CONSP rather than !SCM_NULLP while
	traversing the args list, fixes segv if an improper list is given.
	Reported by Rouben Rostamian.

2004-01-06  Marius Vollmer  <marius.vollmer@uni-dortmund.de>

	* ports.c (swap_ports, scm_with_current_foo_port): Do not allocate
	swap_data on stack, use a 'malloc obj'.

	* fluids.h, fluids.c (scm_make_initial_fluids, scm_copy_fluids,
	scm_swap_fluids, scm_swap_fluids_reverse): Renamed to
	scm_i_... since they are internal.  Changed all uses.

	scm_begin_frame, scm_end_frame, scm_on_unwind, scm_on_rewind):
	New.
	(scm_dowinds, scm_i_dowinds): scm_dowinds has been renamed to
	scm_i_dowinds and extended to handle frames and to invoke a 'turn'
	function when the outermost wind point has been reached.  The
	latter is used to copy a continuation stack at the right time.
	scm_dowinds remains available.
	(SCM_GUARDSP, SCM_BEFORE_GUARD, SCM_AFTER_GUARD, SCM_GUARD_DATA,
	tc16_guard, guards_print): Removed.

2004-01-04  Kevin Ryde  <user42@zip.com.au>

	* numbers.c (scm_less_p): Don't convert frac to float for compares,

	* stime.c (scm_current_time, scm_gettimeofday): Add a comment about
	setzone/restorezone protection for DOS.

2003-12-26  Marius Vollmer  <mvo@zagadka.de>

	and scm_t_uintmax to be defined in scmconfig.h

2003-12-03  Kevin Ryde  <user42@zip.com.au>

	* numbers.c (scm_less_p): Remove spurious xisnan from frac+big case.

	* numbers.c (scm_make_ratio): Check for numerator equal to
	SCM_MOST_NEGATIVE_FIXNUM and bignum denominator the negative of that,
	giving integer -1.

	* numbers.c (scm_real_part): Return fraction unchanged rather than
	converting to flonum.

2003-11-30  Dirk Herrmann  <D.Herrmann@tu-bs.de>

	* modules.c (module_variable): Fixed (and thus simplified) the
	definition of SCM_BOUND_THING_P to reflect the fact that since
	after the 1.4 series of guile, obarrays only hold variable
	objects.

2003-11-30  Marius Vollmer  <mvo@zagadka.de>

	* numbers.c (scm_logand): It's "#b...", not "#\b...".

	From Paul Jarc:

	* read.c (scm_lreadr): Signal an error for invalid escape
	sequences in strings.  Code cleanups too.

	* print.c (scm_iprin1): use \xNN hexadecimal sequences when
	writing control characters in strings.

2003-11-21  Marius Vollmer  <mvo@zagadka.de>

	* ports.c (scm_drain_input): Bug fix: only access the port after

2003-11-22  Dirk Herrmann  <D.Herrmann@tu-bs.de>

	* eval.c (s_bad_define): New static identifier.

	(m_body): Fixed comment.

	(scm_m_define): Don't generate memoized code for definitions that
	are not on the top level.  As a consequence, no memoized code at
	all is generated for definitions any more: Top level definitions
	are executed immediately during memoization and internal
	definitions are handled separately in m_expand_body.

	(scm_unmemocopy, unmemocopy): Removed code for unmemoizing
	definitions.  Consequently, there is no unmemoizing code any more
	that might modify the environment.  Thus, the old scm_unmemocopy
	is removed and the old unmemocopy is renamed to scm_unmemocopy.

	(SCM_CEVAL): The SCM_IM_DEFINE keyword can no longer occur in
	memoized code.  Call EVALCAR for continuations.  Prefer !SCM_NULLP
	over SCM_NIMP in places, where the argument is known to be part of
	a proper list.

	to share some shifting.

	* numbers.c (scm_integer_expt): Don't mpz_init after scm_i_clonebig or
	scm_i_mkbig, since they do so already.  Don't mpz_clear a bignum SCM,
	since gc does this.

2003-11-19  Marius Vollmer  <mvo@zagadka.de>

	* numbers.c (scm_make_ratio): Rewritten to have a simpler
	structure.  Previously, not all cases with a negative denominator
	were covered.

	* numbers.c (mem2decimal_from_point): use scm_divide instead of
	scm_divide2real when forming the fractional part.  This allows
	"#e1.2" to yield 6/5.

	* numbers.c (scm_i_fraction_equalp): Do not treat the return value
	of scm_equal_p as a C boolean, use SCM_FALSEP.  Previously, all
	fractions were equal to each other regardless of value.  Ooops.

	* numbers.c (scm_rationalize): Return an inexact result when given
	inexact arguments.

	* numbers.c (scm_exact_p, scm_inexact_p): Throw error for
	non-numbers.

	* gen-scmconfig.c (main): remove public definition of
	SCM_SIZEOF___INT64 and SCM_SIZEOF_UNSIGNED___INT64 and add
	direct typedef of long_long and ulong_long inside deprecated block
	when appropriate.

	* deprecated.h: move long_long and ulong_long definitions to
	gen-scmconfig.c so that we don't need to add SCM_SIZEOF___INT64
	and SCM_SIZEOF_UNSIGNED___INT64 to the public namespace.

2003-11-17  Marius Vollmer  <mvo@zagadka.de>

	* hash.c (scm_string_hash): New hashing algorithm that takes the

	ASSERT_SYNTAX, ASSERT_SYNTAX_2): New static identifiers.

	(scm_m_and): Use ASSERT_SYNTAX to signal syntax errors.  Avoid
	unnecessary consing when creating the memoized code.

2003-10-09  Kevin Ryde  <user42@zip.com.au>

	* numbers.c (scm_inexact_to_exact): Don't depend on what double->long
	cast gives for values bigger than a long, or for nan or inf.

2003-10-08  Dirk Herrmann  <D.Herrmann@tu-bs.de>

	* smob.h (scm_make_smob_type): Made the declaration match the
	definition.

2003-10-07  Marius Vollmer  <mvo@zagadka.de>

 	* goops.c, objects.h, smob.c, smob.h: Make type names char
        const * instead of char *.  Thanks to Paul Jarc!

2003-10-02  Kevin Ryde  <user42@zip.com.au>

	* strports.c (scm_call_with_output_string): scm_get_output_string
	rather than scm_strport_to_string, so as to guard against the port
	having been closed by the called procedure.  Reported by Nic Ferrier.

2003-09-18  Dirk Herrmann  <D.Herrmann@tu-bs.de>

	* numbers.h (SCM_INEXACTP): Removed uses of SCM_TYP16S.

	* tags.h, deprecated.h (SCM_TYP16S): Deprecated and moved from
	tags.h to deprecated.h.

2003-09-18  Dirk Herrmann  <D.Herrmann@tu-bs.de>

	This set of patches introduces a new tc7 code scm_tc7_number for
	numbers.  Bignums, reals and complex numbers are turned from smobs
	into subtypes of scm_tc7_number.

	* tags.h (scm_tc7_number): New.

	* eq.c (scm_equal_p), eval.c (SCM_CEVAL), evalext.c
	(scm_self_evaluating_p), gc-card.c (scm_i_sweep_card), gc-mark.c
	(scm_gc_mark_dependencies), goops.c (create_smob_classes), hash.c
	(scm_hasher), numbers.c, numbers.h (SCM_NUMP), objects.c
	(scm_class_of), print.c (scm_iprin1), smob.c
	(scm_smob_prehistory): Don't handle bignums, reals and complex
	numbers as subtypes of scm_tc7_smob any more.

	* numbers.h, tags.h (scm_tc16_big, scm_tc16_real,
	scm_tc16_complex): Moved definitions from tags.h to numbers.h.

2003-09-18  Dirk Herrmann  <D.Herrmann@tu-bs.de>

	* numbers.c (scm_make_complex), gc-card.c (scm_i_sweep_card): Use
	sizeof (scm_t_complex) to determine the memory size of the
	malloc'd area for complex numbers.

2003-09-17  Dirk Herrmann  <D.Herrmann@tu-bs.de>

	* numbers.c (scm_bigequal): Fixed.

2003-09-16  Marius Vollmer  <mvo@zagadka.de>

	* stime.c (scm_current_time): 'time' does not set errno so don't
	use SCM_SYSERROR for reporting errors.

2003-09-16  Dirk Herrmann  <D.Herrmann@tu-bs.de>

	This set of patches eliminates the dependency between the
	implementation of evaluator specific memoization codes and special
	constants like #f, '() etc. ('flags'), which are not evaluator
	specific.  The goal is to remove definitions of evaluator
	memoization codes completely from the public interface.  This will
	make it possible to experiment more freely with optimizations of
	guile's internal representation of memoized code.

	* objects.c (scm_class_of): Eliminate dependency on SCM_ISYMNUM.

	* print.c (iflagnames): New array, holding the printed names of
	guile's special constants ('flags').

	(scm_isymnames): Now holds only the printed names of the
	memoization codes.

	(scm_iprin1): Separate the handling of memoization codes and
	guile's special constants.

	* tags.h (scm_tc9_flag, SCM_ITAG9, SCM_MAKE_ITAG9, SCM_ITAG9_DATA,
	SCM_IFLAGNUM): new

	(scm_tc8_char, scm_tc8_iloc, SCM_BOOL_F, SCM_BOOL_T,
	SCM_UNDEFINED, SCM_EOF_VAL, SCM_EOL, SCM_UNSPECIFIED, SCM_UNBOUND,
	SCM_ELISP_NIL, SCM_IM_DISPATCH, SCM_IM_SLOT_REF,
	SCM_IM_SLOT_SET_X, SCM_IM_DELAY, SCM_IM_FUTURE,
	SCM_IM_CALL_WITH_VALUES, SCM_IM_NIL_COND, SCM_IM_BIND): Changed
	values.

	(SCM_IFLAGP): SCM_IFLAGP now only tests for flags.

	(SCM_IFLAGP, SCM_MAKIFLAG, SCM_IFLAGNUM): Generalized to use the
	tc9 macros and scm_tc9_flag.

2003-09-15  Marius Vollmer  <mvo@zagadka.de>

	* posix.c (scm_setgroups): Check that the gid list is not too
	long.  Thanks to Paul Jarc!

2003-09-14  Dirk Herrmann  <D.Herrmann@tu-bs.de>

	* tags.h: Reduced the number of short instructions from 14 to 13.
	The typecode of the former 14th short instruction is now used to
	represent long instructions.  Changed some comments to reflect
	this fact.

	(SCM_MAKISYM): ISYMs get a new tc7 code, namely the one that was
	previously used by SCM_IM_DEFINE.

	(SCM_IM_DEFINE): Turned into a long instruction.

	* eval.c (unmemocopy, SCM_CEVAL): Treat SCM_IM_DEFINE as a long
	instruction.

	* eval.c (SCM_CEVAL): Since characters and iflags have now a tc7
	code that is separate from all instructions, one level of dispatch
	for long instructions can be eliminated.

	* print.c (scm_isymnames): Removed some commented code.

2003-09-12  Marius Vollmer  <mvo@zagadka.de>

	* __scm.h (SCM_FENCE): Use __memory_barrier with the Intel
	compiler on IA64.

	* hashtab.h (scm_tc16_hashtable): Added "extern" declaration.

	* modules.c (scm_module_reverse_lookup): Check that the obarray
	really is a hashtable and do nothing if not.

	* inline.h: Use "extern inline" only with GCC.  Use "static
	inline" else.

2003-09-06  Dirk Herrmann  <D.Herrmann@tu-bs.de>

	* numbers.h (SCM_INEXACTP, SCM_REALP, SCM_COMPLEXP): Removed uses
	of SCM_SLOPPY_INEXACTP, SCM_SLOPPY_REALP and SCM_SLOPPY_COMPLEXP.

	* numbers.h, deprecated.h (SCM_SLOPPY_INEXACTP, SCM_SLOPPY_REALP,
	SCM_SLOPPY_COMPLEXP): Deprecated and moved from numbers.h to
	deprecated.h.

2003-09-06  Dirk Herrmann  <D.Herrmann@tu-bs.de>

	* eq.c (scm_eqv_p, scm_equal_p): Removed uses of
	SCM_SLOPPY_INEXACTP, SCM_SLOPPY_REALP and SCM_SLOPPY_COMPLEXP.

	* eq.c (scm_eqv_p, scm_equal_p): Reordered comparisons from
	0.0==some_expression to some_expression==0.0.  The latter is
	better readable.  The former is preferred by some people, since it
	leads to a compiler error when confusing == with =.  However, when
	using gcc, a warning will be issued if in an if-statement an
	assigment appears.  Since many Guile developers are using gcc,
	such errors will not remain unnoticed anyway.  We can therefore
	focus on better readability.

2003-09-04  Dirk Herrmann  <D.Herrmann@tu-bs.de>

	* tags.h: Added description of Guile's type system.  Removed some
	old and misleading comments.

2003-09-04  Dirk Herrmann  <D.Herrmann@tu-bs.de>

	* unit.c (scm_cvref): Eliminate unnecessary uses of SCM_NIMP,
	SCM_SLOPPY_REALP and SCM_SLOPPY_COMPLEXP.

2003-09-04  Dirk Herrmann  <D.Herrmann@tu-bs.de>

	* numbers.h (SCM_MAKINUM): Define in terms of scm_tc2_int.

	(SCM_INEXACTP, SCM_REALP, SCM_COMPLEXP): Define in terms of the
	respective SLOPPY macro.

2003-09-04  Dirk Herrmann  <D.Herrmann@tu-bs.de>

	* eq.c (scm_equal_p): Use SCM_TYP7 to check if an object is of
	type string, not SCM_TYP7S.

2003-09-03  Kevin Ryde  <user42@zip.com.au>

	* numbers.c (scm_lognot): Correction to docstring, ones-complement not
	2s-complement.

	* stime.c (scm_strptime): Add comment about glibc strptime %s and
	current timezone requiring SCM_DEFER_INTS.

2003-08-30  Neil Jerram  <neil@ossau.uklinux.net>

	* script.c (scm_compile_shell_switches): Make -s switch optional
	if file to be loaded does not begin with a `-'.  (Thanks to Aaron
	VanDevender for the patch!)

2003-08-30  Kevin Ryde  <user42@zip.com.au>

	* numbers.c (scm_lognot): Rewrite using ~ and mpz_com, for directness
	and to have non-integer types rejected as per other logical funcs.
	
2003-08-28  Kevin Ryde  <user42@zip.com.au>

	* gc.h (scm_remember_upto_here_1): Revise comments on the asm form.

2003-08-23  Kevin Ryde  <user42@zip.com.au>

	* simpos.c (scm_system): Remove SCM_DEFER_INTS, system() should be
	thread safe, and could take a long time too.

2003-08-22  Kevin Ryde  <user42@zip.com.au>

	* numbers.c (scm_difference): Correction to bignum - negative inum.

2003-08-14  Kevin Ryde  <user42@zip.com.au>

	* gc.h (scm_remember_upto_here_1, scm_remember_upto_here_2)
	[__GNUC__]: Use volatile asm macros rather than a function call.
	* gc.c (scm_remember_upto_here_1, scm_remember_upto_here_2): Undefine
	macros while defining functions.

	* simpos.c (getenv): Use <stdlib.h> for prototype.
	(scm_system): In docstring, refer to status:exit-val rather than
	"functions above".

2003-08-09  Kevin Ryde  <user42@zip.com.au>

	* srcprop.c (scm_source_properties): Return plist from hash if it's a
	list set by source-properties! rather than an SRCPROPS object,

2003-07-29  Kevin Ryde  <user42@zip.com.au>

	* properties.c (scm_primitive_property_ref): In docstring, note
	parameters to not-found-proc, use hyphens rather than underscores for
	that parameter name.
	(scm_primitive_property_set_x): In docstring, VAL is the value
	parameter not CODE.
	
2003-07-27  Marius Vollmer  <mvo@zagadka.de>

	* print.c (scm_print_symbol_name): handle more weird characters by
	escaping the symbol name properly.  Thanks to Paul Jarc!

	* posix.h (scm_setgroups): New prototype.
	* posix.c (scm_setgroups): New.  Thanks to Paul Jarc!
	(scm_getgroups): Handle groups ids that don't fit into a fixnum.
	Don't use SCM_WRITABLE_VELTS.
	
	* gc.h (SCM_GC_SET_CELL_BVEC): New.
	* gc-card.c (scm_i_init_card_freelist): Use it.  Thanks to
	Matthias Koeppe!

	* __scm.h (SCM_C_INLINE_KEYWORD): New.
	* numbers.c: Use it in place of SCM_C_INLINE so that the code
	compiles when SCM_C_INLINE is undefined.

2003-07-24  Dirk Herrmann  <D.Herrmann@tu-bs.de>

	* __scm.h: Reformulated the architecture and compiler properties
	in terms of properties of scm_t_bits and SCM variables rather than
	in terms of c standard types.  This is since it is not known which
	of the standard types scm_t_bits and SCM variables will be defined
	to.

2003-07-24  Kevin Ryde  <user42@zip.com.au>

	* numbers.c (scm_angle): Use scm_flo0 for non-negative inum, bignum
	and real.

2003-07-18  Kevin Ryde  <user42@zip.com.au>

	* numbers.c (scm_product): In complex * bignum, correction to
	REAL/IMAG fetch, x is the complex, not y.

2003-07-13  Mikael Djurfeldt  <djurfeldt@nada.kth.se>

	* numbers.c (scm_odd_p, scm_even_p): Bugfix: Treat result of
	scm_inf_p test as Scheme values.
	(scm_sum): Bugfix: Normalize bignum created from a negative bignum
	and a positive inum.
	Use GNU indentation style.

2003-07-12  Dirk Herrmann  <D.Herrmann@tu-bs.de>

	* values.c (scm_values): Build lists of length 1 by using
	scm_list_1 instead of using scm_cons.

2003-07-10  Kevin Ryde  <user42@zip.com.au>

	* deprecation.c (scm_c_issue_deprecation_warning_fmt): Add va_end.
	* list.c (scm_list_n): Ditto.

	* gc-malloc.c (scm_gc_realloc): Define "ptr" at start of function.

2003-07-08  Matthias Koeppe <mkoeppe@merkur.math.uni-magdeburg.de>

	* tags.h (scm_t_bits, scm_t_signed_bits, etc): Avoid solaris empty
	defines of INTPTR_MAX and UINTPTR_MAX, combine conditionals for
	scm_t_bits and scm_t_signed_bits to avoid any chance of one and not
	the other using intptr_t.

2003-07-08  Kevin Ryde  <user42@zip.com.au>

	* numbers.c (scm_make_polar): Use sincos, when available.
	(scm_magnitude): Use hypot.

	* ports.c (scm_char_ready_p, scm_peek_char): In docstrings, don't use
	@footnote since it doesn't go through to guile-procedures.txt.

	* threads.c (scm_call_with_new_thread): In docstring, use "( )"
	outside @var to quieten makeinfo, and use @code.

2003-07-06  Han-Wen Nienhuys  <hanwen@cs.uu.nl>

	* gc-malloc.c (decrease_mtrigger): new function
	(increase_mtrigger): new function, separate debug registering and
	mtrigger administration.
	(scm_gc_realloc): bugfix: do mtrigger administration before the
	actual realloc, for the realloc might invalidate a GC-d segment of
	memory. Thanks to Sam Hocevar for pointing this out.
	(scm_gc_realloc): use scm_malloc_reregister instead of
	unregistering and registering in sequence.

2003-07-03  Han-Wen Nienhuys  <hanwen@cs.uu.nl>

	* __scm.h (SCM_ASSERT): change "else" expansion to "do { } while (0)" 

2003-07-02  Han-Wen Nienhuys  <hanwen@cs.uu.nl>

	* __scm.h (SCM_ASRTGO): add "else" to macro expansions with if
	clauses.
	
2003-06-29  Marius Vollmer  <mvo@zagadka.de>

	* deprecated.h (SCM_OPDIRP, scm_fport, scm_option, scm_srcprops,
	scm_srcprops_chunk, scm_info_frame, scm_stack, scm_array,
	scm_array_dim, SCM_ARRAY_CONTIGUOUS, SCM_FUNC_NAME, SCM_WTA,
	RETURN_SCM_WTA, SCM_VALIDATE_NUMBER_COPY,
	SCM_VALIDATE_NUMBER_DEF_COPY, SCM_VALIDATE_OPDIR): Re-added from
	the release_1_6 branch.

2003-06-25  Stefan Jahn  <stefan@lkcc.org>

	* continuations.c: Redeclaration of getcontext() via the
	__asm__ ("getcontext") directive.

	* continuations.h: Include <ucontext.h> instead of 
	<sys/ucontext.h>.

2003-06-21  Kevin Ryde  <user42@zip.com.au>

	* numbers.c (_GNU_SOURCE): #define, to get C99 things.
	(scm_asinh, scm_acosh, scm_atanh, scm_truncate, $asinh, $acosh,
	$atanh, truncate): Use C library asinh, acosh, atanh and trunc, when
	available.
	(scm_inexact_to_exact): Expand isfinite to its definition !xisinf.
	(isfinite): Remove, conflicts with C99 isfinite().

2003-06-19  Marius Vollmer  <mvo@zagadka.de>

	* deprecated.h, deprecated.c (scm_strhash, scm_sym2ovcell_soft,
	scm_sym2ovcell, scm_intern_obarray_soft, scm_intern_obarray,
	scm_symbol_value0, scm_string_to_obarray_symbol scm_intern_symbol,
	scm_unintern_symbol, scm_symbol_binding, scm_symbol_interned_p,
	scm_symbol_bound_p, scm_symbol_set_x, scm_gentemp): Re-added from
	the release_1_6 branch.

2003-06-14  Stefan Jahn  <stefan@lkcc.org>

	* threads.h: Redefined scm_getspecific() and scm_setspecific()
	to be functions instead of macros.

	* threads.c: Conditionalized inclusion of <sys/time.h> and
	<unistd.h>.
	(scm_getspecific, scm_setspecific): Made these two function
	real part of the API.

	* posix.c (s_scm_putenv): Added some code to make a 
	(putenv "FOO="), i.e. setting an empty string, work also on
	Win32 systems.  Thanks to Kevin Ryde for the proposal.

2003-06-12  Kevin Ryde  <user42@zip.com.au>

	* posix.c (scm_putenv): Free temporary ptr in mingw unset.  Add
	freebsd to comment about need to use unsetenv.

2003-06-02  Marius Vollmer  <mvo@zagadka.de>

	* ports.c (scm_peek_char): Safe the column of the port around the
	getc/ungetc calls.  Thanks to Dr. Peter Ivanyi!

2003-06-07  Kevin Ryde  <user42@zip.com.au>

	* tags.h: Use inttypes.h and stdint.h when available, for INTPTR_MAX
	and friends required by scm_t_bits setups.

2003-06-06  Dirk Herrmann  <D.Herrmann@tu-bs.de>

	* tags.h (scm_tc2_int): Added.

	* tags.h (scm_tc3_int_1, scm_tc3_int_2): Expressed in terms of
	scm_tc2_int.

	* tags.h (scm_tcs_cons_imcar, scm_tcs_cons_nimcar, scm_tcs_struct,
	scm_tcs_closures): Hard coded values replaced by symbolic ones.

2003-06-05  Dirk Herrmann  <D.Herrmann@tu-bs.de>

	* eval.c: Partially undid my patch from 2003-05-31.  This patch
	caused the segfault referenced in the previous changelog entry.

2003-06-05  Dirk Herrmann  <D.Herrmann@tu-bs.de>

	* tags.h: Fixed comment about the immediate type code layout.

	* eval.c: Fixed handling of non-special instructions.  Without
	this patch, guile will segfault on (#\0) and similar instructions.

2003-06-05  Kevin Ryde  <user42@zip.com.au>

	* numbers.c (scm_max, scm_min): For inum, bignum and real, if other
	operand is NaN, then return NaN.  Also avoid passing NaN to mpz_cmp_d.

	* read.c (scm_input_error): Pass arg list parameter to scm_error_scm,
	rather than SCM_EOL.  Needed by "Unknown # object" case in scm_lreadr.
	
2003-06-04  Dirk Herrmann  <D.Herrmann@tu-bs.de>

	* __scm.h, gc-card.c (SCM_DEBUG_DEBUGGER_SUPPORT,
	SCM_DEBUG_DEBUGGING_SUPPORT): Renamed macro
	SCM_DEBUG_DEBUGGER_SUPPORT to SCM_DEBUG_DEBUGGING_SUPPORT and
	generalized it to apply not only to C level functions but also to
	scheme level functions.

	* debug.c, debug.h, eval.c (make-iloc, scm_make_iloc, iloc?,
	scm_iloc_p, dbg-make-iloc, scm_dbg_make_iloc, dbg-iloc?,
	scm_dbg_iloc_p): Moved functions scm_make_iloc, scm_iloc_p to
	eval.c, made them available under SCM_DEBUG_DEBUGGING_SUPPORT == 1
	only and renamed them to scm_dbg_make_iloc, scm_dbg_iloc_p,
	respectively.

	* deprecated.h, eval.c, eval.h (SCM_ILOC00, SCM_IDINC,
	SCM_IDSTMSK): Deprecated.  The macro definitions are moved from
	eval.h into eval.c and a copy is placed into deprecated.h.

	* eval.c, eval.h (SCM_MAKE_ILOC): Removed from eval.h and placed
	into eval.c. This definition was not part of the API in any
	officially released version of guile and thus does not need to go
	through a phase of deprecation.

2003-06-02  Dirk Herrmann  <D.Herrmann@tu-bs.de>

	* deprecated.c, deprecated.h, eval.c, eval.h (scm_s_expression,
	scm_s_test, scm_s_body, scm_s_bindings, scm_s_variable,
	scm_s_clauses, scm_s_formals): Deprecated.  In eval.c the
	definitions are make static and renamed from scm_s_xxx to s_xxx.
	In deprecated.c the original definitions are copied.

	* deprecated.h, eval.c, eval (SCM_EVALIM2, SCM_EVALIM, SCM_XEVAL,
	SCM_XEVALCAR): Deprecated.  The macro definitions are moved from
	eval.h into eval.c and a copy (slightly modified to work in user
	code) is placed into deprecated.h.

	* eval.c: Use the local static s_xxx definitions instead of the
	scm_s_xxx definitions throughout.

2003-06-01  Dirk Herrmann  <D.Herrmann@tu-bs.de>

	This set of patches separates the representation of the cxr family
	of functions (car, cdr etc.) from the dsubr family of functions
	(i. e. functions that take a double precision floating point
	argument).  Further, the algorithm for handling the cxr function
	is improved.

	* eval.c (SCM_CEVAL, SCM_APPLY, scm_trampoline_1), numbers.c
	(scm_asinh, scm_acosh, scm_atanh, scm_truncate, scm_round, floor,
	ceil, sqrt, fabs, exp, log, sin, cos, tan, asin, acos, atan, sinh,
	cosh, tanh), objects.c (scm_class_of), procprop.c
	(scm_i_procedure_arity), ramap.c (scm_array_map_x), tags.h
	(scm_tc7_dsubr, scm_tcs_subrs): Introduce scm_tc7_dsubr as new
	typecode for the dsubr family of functions.

	* ramap.c (ramap_cxr, ramap_dsubr): Renamed ramap_cxr to
	ramap_dsubr.

	* eval.c (SCM_CEVAL, SCM_APPLY, call_cxr_1), pairs.c
	(scm_init_pairs): Make use of the (now usable) second cell element
	of a scm_tc7_cxr function to implement the cxr family of functions
	more efficiently.

2003-05-31  Dirk Herrmann  <D.Herrmann@tu-bs.de>

	* eval.c (SCM_CEVAL, SCM_APPLY, scm_trampoline_0,
	scm_trampoline_1, scm_trampoline_2): Postpone error cases to the
	end of an if-else-if-sequence of checks.

2003-05-30  Dirk Herrmann  <D.Herrmann@tu-bs.de>

	* eval.c (SCM_CEVAL): Improved readability of call-with-values
	execution.  Generalize apply_closure to apply_proc and use that
	for call-with-values.

2003-05-30  Dirk Herrmann  <D.Herrmann@tu-bs.de>

	* eval.c (SCM_CEVAL): Avoid one level of indirection when applying
	a non closure.

2003-05-30  Stefan Jahn  <stefan@lkcc.org>

	* posix.c (s_scm_putenv): Use the new HAVE_UNSETENV 
	appropriately for mingw32 hosts.

	* numbers.h: Defining copysign(), isnan() and finite() to
	be prefixed by a single '_' for mingw32 hosts.

2003-05-30  Kevin Ryde  <user42@zip.com.au>

	* numbers.c (z_negative_one): New variable.
	(scm_init_numbers): Initialize it.
	(scm_logcount): Use it and mpz_hamdist to count zeros for negatives.

2003-05-29  Stefan Jahn  <stefan@lkcc.org>

	* win32-dirent.c: Use malloc() instead of scm_malloc().

	* stime.c (s_scm_strftime): Add a type cast to avoid compiler
	warning.

	* posix.c (s_scm_putenv): Disable use of unsetenv() for the
	mingw32 build.

	* modules.c (s_scm_module_import_interface): Renamed local
	variable interface to _interface.  Seems like 'interface'
	is a special compiler directive for the mingw32 compiler.

	* mkstemp.c: Provide prototype to avoid compiler warning.

	* load.c (s_scm_search_path): Fixed absolute and relative
	path detections for native Windows platforms.

	* gc.h, threads.h: Export some more symbols using SCM_API (necessary 
	to build on mingw32).

	* gc-freelist.c ("s_scm_map_free_list", 
	"s_scm_gc_set_debug_check_freelist_x"): Fixed use of FUNC_NAME.

2003-05-19  Dirk Herrmann  <D.Herrmann@tu-bs.de>

	* eval.c (scm_m_do, unmemocopy, SCM_CEVAL):  Reversed order of
	names and inits in the memoized code of do.

2003-05-19  Mikael Djurfeldt  <djurfeldt@nada.kth.se>

	* c-tokenize.lex (yyget_lineno, yyget_in, yyget_out, yyget_leng,
	yyget_text, yyset_lineno, yyset_in, yyset_out, yyget_debug,
	yyset_debug, yylex_destroy): Added prototypes (otherwise we'll get
	a compilation error if error-on-warning is enabled).

2003-05-17  Marius Vollmer  <mvo@zagadka.de>

	* c-tokenize.lex: Gobble up complete lines after a '#'.  This
	removes preprocessor directives from the snarfage that might
	otherwise confuse us.  These directives appear when compiling with
	"-g3", for example.

2003-05-16  Han-Wen Nienhuys  <hanwen@cs.uu.nl>

	* ChangeLog: add my surname

	* srcprop.c (scm_finish_srcprop): use

	want ones-complement.

	* numbers.c (scm_gcd): In bignum/inum, don't pass yy==0 to mpz_gcd_ui
	since we're only using the ulong return value, and x might not fit.

2003-05-06  Dirk Herrmann  <D.Herrmann@tu-bs.de>

	* eval.c, eval.h, read.c, read.h (scm_sym_dot): Moved from eval to
	read.  This will allow to make the definition in read.c static.

2003-05-06  Dirk Herrmann  <D.Herrmann@tu-bs.de>

	* eval.c, eval.h, evalext.c, evalext.h (scm_m_undefine): Moved
	from evalext to eval.  This will allow to make some of the
	definitions in eval.c static.

2003-05-06  Kevin Ryde  <user42@zip.com.au>

	* numbers.c (scm_difference): In inum - bignum, handle negative inum.
	(scm_logcount): Use mpz_com, not mpz_neg.

2003-05-04  Dirk Herrmann  <D.Herrmann@tu-bs.de>

	The purpose of this patch is to make guile's internal memoizers
	distinguishable from memoizing macros created on the scheme level
	or from user provided primitive memoizing macros.  The reason is,
	that the internal memoizers are the only ones that are allowed to
	transform their scheme input into memoizer byte code, while all
	other memoizing macros may only transform scheme code into new
	scheme code.

	To achieve this, a new macro type 'builtin-macro!' is introduced.
	Currently, 'builtin-macro!'s are handled as memoizing macros, but
	this will change when the memoizer and executor are separated.

	* macros.[ch] (scm_i_makbimacro): New.

	* macros.h (SCM_BUILTIN_MACRO_P): New.

	* macros.c (macro_print, scm_macro_type): Support builtin-macro!s.

	* eval.c, goops.c: All of guile's primitive memoizing macros are
	primitive builtin-macros now.

	* eval.c (scm_macroexp, SCM_CEVAL): Make sure the primitive
	builtin-macros are handled equally to memoizing macros.

2003-05-04  Marius Vollmer  <mvo@zagadka.de>

	* throw.c (scm_ithrow): Remove "asm volatile" hack.  It used to
	work around a bug in GCC 2.95.2 but is now a bug in itself.

2003-05-02  Marius Vollmer  <mvo@zagadka.de>

	* deprecated.h (scm_rstate, scm_rng, SCM_SLOPPY_CONSP,

	* ports.c (scm_c_port_for_each): New function, mostly copied from
	scm_port_for_each.
	(scm_port_for_each): Reimplemented using scm_c_port_for_each.
	* ports.h (scm_c_port_for_each): New prototype.
	
2003-04-28  Mikael Djurfeldt  <djurfeldt@nada.kth.se>

	* eval.c (scm_m_atdispatch): Removed until actually needed.  (This
	macro was introduced in anticipation of GOOPS method compilation
	code.)

	* goops.c: Removed binding of @dispatch.

2003-04-28  Dirk Herrmann  <D.Herrmann@tu-bs.de>

	* eval.c, goops.c (@dispatch, @slot-ref, @slot-set!): Move the
	instructions that bind the macros on the scheme level back to
	goops.c in order to make sure again that the bindings go into the
	(oop goops) module and are not visible from the outside.

2003-04-27  Dirk Herrmann  <D.Herrmann@tu-bs.de>

	* eval.c: Non functional change: Separated R5RS and non-R5RS
	macros into different sections of the file and ordered the
	memoizers alphabetically.

2003-04-27  Dirk Herrmann  <D.Herrmann@tu-bs.de>

	* eval.c (scm_ilookup):  Rewritten to improve readability.

2003-04-27  Dirk Herrmann  <D.Herrmann@tu-bs.de>

	compromise between readability and debuggability.

2003-04-25  Dirk Herrmann  <D.Herrmann@tu-bs.de>

	* eval.c, eval.h, goops.c, goops.h (scm_m_atslot_ref,
	scm_m_atslot_set_x, scm_m_atdispatch): Move the declarations and
	definitions of the special goops memoizers from goops.[ch] to
	eval.[ch].  Hmm... it seems that scm_m_atdispatch is not used
	throughout guile.

2003-04-24  Mikael Djurfeldt  <mdj@kvast.blakulla.net>

	* ports.c, ports.h (scm_i_port_table_mutex): New mutex.

	* fports.c (scm_fdes_to_port): Ditto.

2003-04-23  Dirk Herrmann  <D.Herrmann@tu-bs.de>

	This set of patches contains no functional changes, only debatable
	minor stylistic ones.  Still, in order to prepare a patch between
	my local copy and the CVS version, I decided to submit the changes
	below.  Then, the patch will hopefully only contain relevant
	modifications :-)

	* eval.c (iqq): Added const specifier.

	* eval.c (scm_trampoline_0, scm_trampoline_1, scm_trampoline_2):
	Use NULL instead of 0 to indicate that a pointer is returned.

	Split up long expressions into smaller ones to be more debugging
	friendly.

2003-04-23  Dirk Herrmann  <D.Herrmann@tu-bs.de>

	* eval.h (SCM_ENTER_FRAME_HDLR, SCM_APPLY_FRAME_HDLR,

	rather than casting to SCM.

2003-04-23  Dirk Herrmann  <D.Herrmann@tu-bs.de>

	* sort.c, pairs.h: Removed unnecessary includes.

2003-04-23  Dirk Herrmann  <D.Herrmann@tu-bs.de>

	* sort.c: Replaced hand-made trampline code by the new official
	mechanism from eval.c.  This fixes a segfault in the new test file
	sort.test.

	(quicksort, compare_function, scm_restricted_vector_sort_x,
	scm_sorted_p, scm_merge, scm_merge_list_x, scm_merge_x,
	scm_merge_list_step, scm_sort_x, scm_sort, scm_merge_vector_x,
	scm_merge_vector_step, scm_stable_sort_x, scm_stable_sort,
	scm_sort_list_x, scm_sort_list): Use trampoline mechanism from
	eval.c.

	(subr2less, lsubrless, closureless, applyless, scm_cmp_function,
	cmp_fun_t): Removed.

	(compare_function): Added.

	* sort.c (quicksort, SWAP, stack_node): Replaced pointer
	arithmetics with index arithmetics.  Changed quicksort to work on
	an array of SCM values instead of an array of characters.  Avoid
	bytewise copying of SCM elements.  Avoid allocating memory on the
	stack with alloca.  Fixed some comments.

2003-04-21  Dirk Herrmann  <D.Herrmann@tu-bs.de>

	* eval.c (EXTEND_ENV): Eliminated.

	(unmemocopy, SCM_CEVAL, SCM_APPLY): Use SCM_EXTEND_ENV instead of

	scm_t_list_cell_struct, scm_t_list_cell, scm_t_double_cell,
	scm_gc_marked_p, scm_gc_get_card, scm_gc_get_bvec): Fixed
	functions such that they check if the object is a non-immediate.
	Further, renamed identifiers to use the scm_dbg_ prefix and made
	their inclusion into the lib dependent of the
	SCM_DEBUG_DEBUGGER_SUPPORT compile time option.

2003-04-21  Dirk Herrmann  <D.Herrmann@tu-bs.de>

	* __scm.h: Fixed comment about the SCM_DEBUG_TYPING_STRICTNESS

	scm_m_generalized_set_x, scm_init_evalext): Move the declaration
	and definition of the memoizer for the generalized set! macro from
	evalext.[ch] to eval.[ch].  Use the SCM_SYNTAX snarfer macro to
	define the macro object.

	* eval.c, eval.h (s_set_x, scm_s_set_x, scm_m_set_x,
	scm_m_generalized_set_x): Since now scm_s_set_x is only used in
	eval.c, it is made static and renamed to s_set_x.

	scm_at_assert_bound_ref.  (We don't want the unbound check.  See
	oop/goops/active-slot.scm.)

2003-04-14  Rob Browning  <rlb@defaultvalue.org>

	* tags.h: scm_t_intptr should have been intptr_t.

2003-04-13  Rob Browning  <rlb@defaultvalue.org>

	* __scm.h (SCM_FLUSH_REGISTER_WINDOWS): don't just rely on "sparc"
	test.  Instead use

	* posix.h: change occurences of "id" to something else so we don't
	cause trouble when included via objective-c (can't hurt, might

2003-04-06  Mikael Djurfeldt  <djurfeldt@nada.kth.se>

	* random.c (scm_c_random_bignum): Don't generate a random number
	equal to m (the second argument of scm_c_random_bignum); only

	scm_var_random_state.

	* num2integral.i.c (INTEGRAL2BIG): Put negation of n inside then
	clause.

	scm_assoc.

	* eq.c (scm_equal_p): Turned into a primitive generic.

2003-02-24  Mikael Djurfeldt  <djurfeldt@nada.kth.se>

	This fixes a serious GC bug, introduced during the latest
	reorganization of the GC, which disabled freeing of structs and
	GOOPS objects:

	* struct.c (scm_struct_prehistory): Init scm_i_structs_to_free to
	SCM_EOL.
	(scm_struct_prehistory): Move scm_free_structs to
	scm_before_mark_c_hook.

	* gc-card.c (sweep_card): Check that we haven't swept structs on
	this card before.  That can happen if scm_i_sweep_all_segments has
	been called from some other place than scm_igc.

2003-02-19  Mikael Djurfeldt  <djurfeldt@nada.kth.se>

	* environments.c (DEFAULT_OBARRAY_SIZE): Changed from 137 to 31
	(since hash tables now adapt their size).

	* modules.c (scm_modules_prehistory): Changed from 2001 to 1533
	(current number of prehistory bindings; hashtable code will select
	a prime which is greater than this value).

	* symbols.c (scm_symbols_prehistory): Changed from 1009 to 2139
	(current number of initial symbols).

	* properties.c (scm_init_properties): Don't specify size of
	scm_properties_whash.

	* objprop.c (scm_init_objprop): Don't specify size of

	The following changes introduce the use of resizable hash tables
	throughout Guile.  It also renames the old *-hash-table* functions
	to *-alist-vector* and places them, together with the rest of the
	weak vector support, in the module (ice-9 weak-vector).  We should
	probably introduce a new, better, API for weak references, for
	example "weak pairs" a la MIT-Scheme.  (In Chez scheme, they even
	look like and are used like ordinary pairs.)

	* environments.c (obarray_enter, obarray_retrieve, obarray_remove,
	leaf_environment_fold, obarray_remove_all): Use hashtable
	accessors.

	* gc.c (scm_init_storage): Moved hook initialization to
	scm_storage_prehistory.
	(scm_storage_prehistory): New function.
	(scm_igc): Added commentary about placement of
	scm_after_sweep_c_hook.

	SCM_WVECT_WEAK_VALUE_P.

	functions.
	(scm_vector_to_hash_table, scm_c_make_resizing_hash_table):
	Removed.
	(scm_make_weak_key_hash_table, scm_make_weak_value_hash_table,
	scm_make_doubly_weak_hash_table): Moved here from weaks.c.

	* init.c (scm_init_guile_1): Removed call to scm_init_weaks; Added
	calls to scm_storage_prehistory and scm_hashtab_prehistory.

	* modules.c (module-reverse-lookup): Use hashtable accessors.

	* symbols.c, symbols.h (scm_i_hash_symbol): New function.

	* weaks.c, weaks.h (scm_make_weak_key_alist_vector,
	scm_make_weak_value_alist_vector,
	scm_make_doubly_weak_alist_vector): New functions.

	* weaks.c (scm_init_weaks_builtins): New function.

	* weaks.h (SCM_WVECTF_WEAK_KEY, SCM_WVECTF_WEAK_VALUE,
	SCM_WVECTF_NOSCAN, SCM_WVECT_WEAK_KEY_P, SCM_WVECT_WEAK_VALUE_P,

	* weaks.c (scm_scan_weak_vectors):  Use SCM_WVECT_WEAK_KEY_P
	and SCM_WVECT_WEAK_VALUE_P.

	* weaks.c, weaks.h (scm_i_allocate_weak_vector): Renamed from
	allocate_weak_vector and exported.

2003-02-13  Mikael Djurfeldt  <djurfeldt@nada.kth.se>

	* hashtab.c: Undid thread safety.  (We decided that it's better to
	let the user explicitly protect the tables (or not) according what
	is suitable for the application.)

2003-02-12  Mikael Djurfeldt  <djurfeldt@nada.kth.se>

	* hashtab.c (scm_hash_fn_remove_x, scm_internal_hash_fold): Made
	thread safe and handle resizing tables.
	(scm_ihashx, scm_sloppy_assx, scm_delx_x): Removed
	SCM_DEFER/ALLOW_INTS.

2003-02-11  Mikael Djurfeldt  <djurfeldt@nada.kth.se>

	scm_c_make_resizing_hash_table, scm_make_hash_table): New
	functions.
	(scm_hash_fn_get_handle, scm_hash_fn_create_handle_x): Made thread
	safe and handle resizing tables.

	Size argument made optional.  Return resizable table if not
	specified.

2003-02-10  Mikael Djurfeldt  <djurfeldt@nada.kth.se>

	* eval.c (scm_trampoline_0, scm_trampoline_1, scm_trampoline_2):
	Fixed formals tests for closures.  (Thanks to Kevin Ryde.)

2003-02-05  Mikael Djurfeldt  <djurfeldt@nada.kth.se>

	* debug.c (scm_procedure_source): Handle all objects for which
	procedure? is #t.  (Thanks to Bill Schottstaedt.)

2003-01-23  Mikael Djurfeldt  <djurfeldt@nada.kth.se>

	* futures.c (mark_futures): Don't need to mark data of recycled
	futures.
	(scan_futures, cleanup_undead): Be smarter about marking
	futures---avoid unnecessary passes through future lists.

	* futures.h, futures.c: New files; Introduced recycling of
	futures.  For fine-grained threading this lifts performance to
	another level.  We can now use parallelization in inner loops of
	Guile programs without impossible overhead.

	* threads.h, threads.c: Moved futures to their own file.

	* Makefile.am (libguile_la_SOURCES): Added futures.c.
	(DOT_X_FILES): Added futures.x.

	(scm_init_guile_1): Call scm_init_futures.

	* stime.c (SCM_TIME_UNITS_PER_SECOND): Renamed from CLKTCK.

	* stime.h (SCM_TIME_UNITS_PER_SECOND): Definition moved here.

	* eval.c, eval.h (scm_trampoline_0, scm_i_call_closure_0): New
	functions.

	* eval.c (scm_trampoline_1): Fixed arguments test for closures.

2003-01-22  Mikael Djurfeldt  <djurfeldt@nada.kth.se>

	* threads.c (create_thread): Don't unwind dynwind chain of parent
	thread before creation.  Just start the new thread with an empty
	dynwind chain.

2003-01-20  Mikael Djurfeldt  <djurfeldt@nada.kth.se>

	* evalext.c, evalext.h (scm_self_evaluating_p): New function.

	waiting also for simple condition variables.

	* goops.c (TEST_CHANGE_CLASS): Use scm_change_object_class instead
	of calling the procedure change-object-class.

2003-01-09  Mikael Djurfeldt  <djurfeldt@nada.kth.se>

	* ramap.c (scm_ramapc): Typo in error message.

2003-01-08  Mikael Djurfeldt  <djurfeldt@nada.kth.se>

	slots with instance allocation.
	
	* goops.c, goops.h (scm_class_extended_generic_with_setter): New
	class.
	(scm_compute_applicable_methods): Use scm_generic_function_methods.

	* goops.c (scm_generic_function_methods): Support extended
	generic functions.

2002-12-29  Mikael Djurfeldt  <djurfeldt@nada.kth.se>

	* eval.c (unmemocopy): Bugfix: scm_sym_delay --> scm_sym_future.
	Thanks to Neil for pointing this out!

2002-12-29  Neil Jerram  <neil@ossau.uklinux.net>

	* lang.h: Remove declarations matching definitions removed from
	lang.c (just below).

2002-12-28  Neil Jerram  <neil@ossau.uklinux.net>

	* lang.c (scm_nil_cons, scm_nil_car, scm_nil_cdr, scm_null,
	scm_m_while, scm_nil_eq): Remove definitions that were superfluous
	and already commented out.

	* read.h (scm_lreadparen), read.c (scm_lreadr, scm_read_token,
	scm_lreadparen): Support reading vectors with Elisp syntax if
	SCM_ELISP_READ_EXTENSIONS is defined.  (SCM_ELISP_READ_EXTENSIONS
	is not currently defined, and there isn't even a configure switch
	to enable it yet.)

2002-12-26  Marius Vollmer  <mvo@zagadka.ping.de>

	* Makefile.am (c-tokenize.o): Refer to source via $< so that vpath
	builds work.
	(EXTRA_DIST): Added version.h.in.
	
2002-12-21  Mikael Djurfeldt  <djurfeldt@nada.kth.se>

	This change makes it possible for one thread to do lazy sweeping
	while other threads are running.  Now only the mark phase need to
	have all threads asleep.  We should look further into this issue.
	Presently, I've put the locking of scm_i_sweep_mutex at
	"conservative" places due to my current lack of knowledge about
	the garbage collector.  Please feel free to restrict these regions
	further to allow for maximal parallelism!

	* gc.c, gc.h (scm_i_sweep_mutex): New mutex.

	* gc.c (scm_gc_for_newcell), gc-malloc.c (scm_realloc,
	scm_gc_register_collectable_memory): Substitute locking of
	scm_i_sweep_mutex for calls to scm_i_thread_put_to_sleep.
	(scm_igc): Lock sweep mutex here instead of in callers; Calls to
	scm_i_thread_put_to_sleep/scm_i_thread_wake_up used to demarkate
	the single-thread section (which now only contains the mark
	phase).
	(scm_gc): Don't lock sweeo mutex here since scm_igc locks it;
	Removed SCM_DEFER/ALLOW_INTS.  Simply call scm_igc directly.

	* threads.c (gc_section_mutex): Removed.

2002-12-19  Mikael Djurfeldt  <mdj@kvast.blakulla.net>

	* threads.c (create_thread): Clear parent field in root state in
	order not to unnecessarily remember dead threads.

	* eval.c (call_subr2o_1, call_lsubr2_2): New functions.
	(scm_trampoline_1, scm_trampoline_2): Use them.

2002-12-18  Mikael Djurfeldt  <mdj@kvast.blakulla.net>

	Partial introduction of real plugin interface.

	* Makefile.am (modinclude_HEADERS): Added threads-plugin.h.
	(EXTRA_DIST): Added threads-plugin.c.

	* threads-plugin.h, threads-plugin.c: New files.

	* threads.h: #include "libguile/threads-plugin.h".

	* threads.c: #include "libguile/threads-plugin.c".

	* pthread-threads.c: Temporarily remove debugging functions.

	* threads.c, threads.h (scm_yield): Added back.

2002-12-18  Mikael Djurfeldt  <mdj@kvast.blakulla.net>

	* threads.c (really_launch): Detach before unlocking
	thread_admin_mutex in order not to risk being joined.
	(scm_i_thread_put_to_sleep, scm_i_thread_wake_up): Keep
	thread_admin_mutex locked during GC.

	* pthread-threads.c, pthread-threads.h: Improvements to debugging
	functions.

2002-12-16  Mikael Djurfeldt  <mdj@kvast.blakulla.net>

	* pthread-threads.c, pthread-threads.h (SCM_DEBUG_THREADS): Added
	support for debugging mutex operations.

	* threads.c (scm_thread): Removed filed joining_threads.
	(thread_print): Print thread number as well as address of thread
	structure.
	(scm_join_thread): Bugfix.
	(scm_lock_mutex, scm_try_mutex, scm_unlock_mutex,
	scm_timed_wait_condition_variable, scm_signal_condition_variable,
	scm_broadcast_condition_variable): Use the low-level API.
	(scm_all_threads): Return copy of thread list (to prevent
	unintended destruction).
	(scm_threads_prehistory): Initialize heap_mutex of fake thread.

	* pthread-threads.c, pthread-threads.h, threads.c: Fixes to
	pthread "native" recursive mutex support.

2002-12-15  Mikael Djurfeldt  <djurfeldt@nada.kth.se>

	* __scm.h (SCM_DEFER_INTS, SCM_ALLOW_INTS): New definitions.
	Simply lock a thread C API recursive mutex.
	(SCM_NONREC_CRITICAL_SECTION_START,
	SCM_NONREC_CRITICAL_SECTION_END, SCM_REC_CRITICAL_SECTION_START,
	SCM_REC_CRITICAL_SECTION_END): Removed.

	* eval.c: Replaced SOURCE_SECTION_START / SOURCE_SECTION_END with
	direct calls to scm_rec_mutex_lock / unlock around the three calls
	to scm_m_expand_body.

	* eval.c, eval.h (promise_free): New function.
	(scm_force): Rewritten;  Now thread-safe; Removed
	SCM_DEFER/ALLOW_INTS.

	* pthread-threads.h: Added partially implemented plugin interface
	for recursive mutexes.  These are, for now, only intended to be
	used internally within the Guile implementation.

	* pthread-threads.c: New file.

	* threads.c: Conditionally #include "pthread-threads.c".

	* eval.c, eval.h (scm_makprom, scm_force): Rewritten to be
	thread-safe;

	* snarf.h (SCM_MUTEX, SCM_GLOBAL_MUTEX, SCM_REC_MUTEX,
	SCM_GLOBAL_REC_MUTEX): New macros.

	* eval.c, threads.c, threads.h, snarf.h: Rewrote critical section
	macros---use mutexes instead.

	* tags.h (SCM_IM_FUTURE): New tag.

	* eval.c (scm_m_future): New primitive macro.
	(SCM_CEVAL): Support futures.
	(unmemocopy): Support unmemoization of futures.

	* print.c (scm_isymnames): Name of future isym.

	* version.c: Unmade some changes to my private copy that got
	committed by mistake.

2002-12-11  Mikael Djurfeldt  <mdj@kvast.blakulla.net>

	* gc-malloc.c, gc.h, init.c: Reverted gc-malloc change of
	2002-12-10.

	* gc.c (scm_igc): Don't call scm_i_thread_invalidate_freelists.

	* gc.c (scm_gc_sweep): Call it here instead, which is a more
	logical place.

	* threads.c (create_thread): Remember root object until the handle
	of the new thread is on all_threads list.

	* root.c (scm_make_root): Moved copying of fluids until after
	creation of root handle so that the fluids are GC protected.  Also
	removed the critical section.

2002-12-10  Mikael Djurfeldt  <mdj@kvast.blakulla.net>

	* gc-malloc.c, gc.h (scm_gc_malloc_prehistory): New function.

	* gc-malloc.c (malloc_mutex): New mutex.
	(scm_gc_malloc_prehistory): Initialize it.
	(scm_realloc): Serialize call to realloc
	(scm_calloc): Same for calloc.
	Thanks to Wolfgang Jaehrling!
	(Now we have to make sure all calls to malloc/realloc are made
	through scm_malloc.)

	* init.c (scm_init_guile_1): Call scm_gc_malloc_prehistory.

	* threads.c (really_launch): Release heap (to prevent deadlock).
	(create_thread): Release heap before locking thread admin mutex.

2002-12-10  Mikael Djurfeldt  <mdj@kvast.blakulla.net>

	* threads.c (scm_i_thread_invalidate_freelists): New
	function.

	* gc.c (scm_igc): Call scm_i_thread_invalidate_freelists.

	* modules.c (scm_export): Inserted a return statement.

2002-12-10  Han-Wen Nienhuys  <hanwen@cs.uu.nl>

	* modules.c (scm_export): new function

	* gc-card.c: add a note about malloc()/free() overhead.

2002-12-10  Mikael Djurfeldt  <mdj@kvast.blakulla.net>

	* Makefile.am (c-tokenize.$(OBJEXT)): Don't look for c-tokenize.c
	in srcdir.

2002-12-10  Mikael Djurfeldt  <djurfeldt@nada.kth.se>

	These changes remove scm_ints_disabled (which hasn't has any
	effect in Guile for quite some time).
	
	* async.c, error.h (scm_ints_disabled): Removed.

	* gc.c (scm_gc_for_newcell), init.c (scm_init_guile_1),
	root.c (scm_internal_cwdr), gdbint.c (SCM_BEGIN_FOREIGN_BLOCK,
	SCM_END_FOREIGN_BLOCK): Don't touch scm_ints_disabled.
	(old_ints): Removed.

	* __scm.h (SCM_DEFER_INTS, SCM_ALLOW_INTS): Define as a recursive
	critical section.
	(SCM_REDEFER_INTS, SCM_ALLOW_INTS): Define as SCM_DEFER_INTS and
	SCM_ALLOW_INTS.

2002-12-09  Mikael Djurfeldt  <djurfeldt@nada.kth.se>

	* threads.c (scm_mutex_lock, scm_cond_wait, scm_cond_timedwait):
	Removed accidental #if 0 around these functions.

	These changes are the start of support for preemptive
	multithreading.  Marius and I have agreed that I commit this code
	into the repository although it isn't thoroughly tested and surely
	introduces many bugs.  The bugs should only be exposed when using
	threads, though.  Signalling and error handling for threads is
	very likely broken.  Work on making the implementation cleaner and
	more efficient is needed.
	
	* __scm.h (SCM_ALLOW_INTS_ONLY): Removed.
	(SCM_NONREC_CRITICAL_SECTION_START,
	SCM_NONREC_CRITICAL_SECTION_END, SCM_REC_CRITICAL_SECTION_START,
	SCM_REC_CRITICAL_SECTION_END): New macros.
	(SCM_CRITICAL_SECTION_START/END): Defined here.

	* eval.c: Insert SOURCE_SECTION_START / SOURCE_SECTION_END around
	the three calls to scm_m_expand_body.

	* gc.h: #include "libguile/pthread-threads.h";
	(SCM_FREELIST_CREATE, SCM_FREELIST_LOC): New macros.

	* gc.c (scm_i_freelist, scm_i_freelist2): Defined to be of type
	scm_t_key;

	* gc.c, gc-freelist.c, inline.h: Use SCM_FREELIST_LOC for freelist
	access.

	* gc-freelist.c (scm_gc_init_freelist): Create freelist keys.

	* gc-freelist.c, threads.c (really_launch): Use
	SCM_FREELIST_CREATE.

	* gc-malloc.c (scm_realloc, scm_gc_register_collectable_memory):

	* gc.c (scm_i_expensive_validation_check, scm_gc,
	scm_gc_for_newcell): Put threads to sleep before doing GC-related
	heap administration so that those pieces of code are executed
	single-threaded.  We might consider rewriting these code sections
	in terms of a "call_gc_code_singly_threaded" construct instead of
	calling the pair of scm_i_thread_put_to_sleep () and
	scm_i_thread_wake_up ().  Also, we would want to have as many of
	these sections eleminated.

	* init.c (scm_init_guile_1): Call scm_threads_prehistory.

	* inline.h: #include "libguile/threads.h"

	* pthread-threads.h: Macros now conform more closely to the
	pthreads interface.  Some of them now take a second argument.

	* threads.c, threads.h: Many changes.

2002-12-09  Mikael Djurfeldt  <djurfeldt@nada.kth.se>

	* Makefile.am (version.h): Changed $^ --> $< in rule for
	version.h.
	
2002-12-08  Rob Browning  <rlb@defaultvalue.org>

	* version.h.in (SCM_MICRO_VERSION): use @--@ substitution now.
	(SCM_MINOR_VERSION): use @--@ substitution now.
	(SCM_MICRO_VERSION): use @--@ substitution now.
	(scm_effective_version): new function prototype.

	* version.c (scm_effective_version): new function, also add
	effective-version.

	* Makefile.am (schemelibdir): VERSION -> GUILE_EFFECTIVE_VERSION.
	(libpath.h): use GUILE_EFFECTIVE_VERSION to compute
	SCM_LIBRARY_DIR.
	(version.h): generate this here rather than configure.in.  This
	approach tracks source edits better (i.e. more immediately).
	Might be worth considering for other .in files too.

2002-12-02  Marius Vollmer  <mvo@zagadka.ping.de>

	Reorganized thread package selection.  A thread package now only
	implements a small set of pthread like functions and Guile
	implements the rest on top of that.  Guile's implementation is
	what the "coop-pthreads" package has been previously.  Support for
	"coop" threads has been removed until I get time to add it again.
	
	* Makefile.am (libguile_la_SOURCES): Removed iselect.c.
	(noinst_HEADERS): Removed coop-threads.c, coop-threads.h, coop.c,
	null-threads.c, coop-pthreads.c.
	(modinclude_HEADERS): Removed coop-defs.h, coop-pthreads.h.  Added
	pthread-threads.h.
	
	* validate.h (SCM_VALIDATE_THREAD): Moved to threads.h.

	* threads.h: Do not include "libguile/coop-defs.h".  Include
	"libguile/pthread-threads.h" for USE_COPT_THREADS.  Removed
	(previously deprecated) C level thread API prototypes.  They are
	now in the thread package specific headers, "null-threads.h" and
	"pthread-threads.h".
	(SCM_VALIDATE_THREAD, SCM_VALIDATE_MUTEX, SCM_VALIDATE_CONDVAR):
	New.
	(scm_threads_init): Removed.
	(SCM_CRITICAL_SECTION_START, SCM_CRITICAL_SECTION_END,
	SCM_THREAD_SWITCHING_CODE, scm_i_switch_counter,
	SCM_I_THREAD_SWITCH_COUNT): Define here.
	(scm_single_thread_p): Removed.
	(scm_call_with_new_thread): Take two args directly instead of list
	of two args.
	(scm_i_thread_data, scm_i_set_thread_data, SCM_THREAD_LOCAL_DATA,
	SCM_SET_THREAD_LOCAL_DATA): Define here.

	* threads.c: Merged with "coop-pthreads.c".

	* null-threads.h: Implement pthread-like API as a set of macros.

	* pthread-threads.h: New, implement pthread-like API by deferring
	to pthread itself.
	
	* init.c (scm_init_guile_1): Do not call scm_init_iselect, which
	has been lost in the reorganization.

2002-12-01  Mikael Djurfeldt  <mdj@linnaeus>

	The following change makes it possible to move procedure
	application dispatch outside inner loops.  The motivation was
	clean implementation of efficient replacements of R5RS primitives
	in SRFI-1.

	The semantics is clear: scm_trampoline_N returns an optimized
	version of scm_call_N (or NULL if the procedure isn't applicable
	on N args).

	Applying the optimization to map and for-each increases efficiency
	noticeably.  For example, (map abs ls) is 8 times faster than
	before.

	* eval.h (scm_t_trampoline_1, scm_t_trampoline_2): New types.

	* eval.c, eval.h (scm_trampoline_1, scm_trampoline_2): New functions.

	* eval.c (call_subr2_2, call_lsubr_2, call_closure_2): New functions;
	(map, for-each): Handle also application on two args as a special
	case; Use trampolines.

	Other changes:
	
	* sort.c (scm_cmp_function): Choose subr2less for scm_tc7_subr_2o;
	(subr2oless): Removed.
	(scm_restricted_vector_sort_x): Use scm_return_first to keep the
	vector GC protected.

	* eval.c (check_map_args): Use scm_out_of_range_pos instead of
	scm_out_of_range.

2002-11-24  Dirk Herrmann  <D.Herrmann@tu-bs.de>

	* evalext.[ch] (scm_m_undefine, undefine):  Deprecated.

2002-11-17  Mikael Djurfeldt  <mdj@linnaeus>

	* debug.c (scm_make_iloc): Added missing "return".

2002-11-17  Marius Vollmer  <mvo@zagadka.ping.de>

	* strports.c (scm_eval_string_in_module): Validate second arg to
	be a module.  Thanks to Arno Peters!

2002-11-16  Dirk Herrmann  <D.Herrmann@tu-bs.de>

	* .cvsignore: remove goops.c

2002-11-16  Dirk Herrmann  <D.Herrmann@tu-bs.de>

	* modules.c (scm_env_top_level, scm_lookup_closure_module,
	module_variable, scm_module_lookup_closure,
	scm_module_transformer, scm_sym2var, scm_module_reverse_lookup,
	scm_system_module_env_p):  Don't compare SCM values with C
	operators == or !=.  Avoid SCM_IMP predicates.  Prefer !SCM_FALSEP
	over SCM_NFALSEP.

2002-11-16  Dirk Herrmann  <D.Herrmann@tu-bs.de>

	* eval.h (SCM_MAKE_ILOC):  New macro.

	* debug.c (scm_make_iloc):  Use SCM_MAKE_ILOC instead of computing
	the iloc bitpattern here.

2002-11-14  Mikael Djurfeldt  <mdj@linnaeus>

	* coop-pthreads.c, coop-pthreads.h: scm_internal_select should be
	part of the API, otherwise it's difficult to write Guile
	extensions using non-blocking I/O => moved #include
	"libguile/iselect.h" from coop-pthreads.c --> coop-pthreads.h.

	* coop-pthreads.c (scm_unlock_mutex): Changed s_lock_mutex -->
	s_unlock_mutex.

2002-11-10  Marius Vollmer  <mvo@zagadka.ping.de>

	* __scm.h (USE_THREADS, GUILE_ISELECT): Do not define here.  They
	are defined in configure.in.

	* threads.c: Removed SCM_API from function definitions.  SCM_API
	is only for declarations.

2002-11-07  Mikael Djurfeldt  <mdj@linnaeus>

	* coop-pthreads.h: Added support for thread specific data to the
	generic C API for the coop-pthreads case.

	* threads.c, threads.h (scm_cond_init): Undo unintentional API
	change.
	(scm_cond_broadcast): Added missing function.

2002-11-04  Marius Vollmer  <marius.vollmer@uni-dortmund.de>

	* coop.c (coop_next_runnable_thread): Removed, wich should have
	happened when GUILE_ISELECT was hard-wired.

2002-11-03  Marius Vollmer  <mvo@zagadka.ping.de>

	* Makefile.am (libguile_la_SOURCES): Added threads.c
	(DOT_DOC_FILES): Added threads.doc.
	(DOT_X_FILES): Added threads.x.
	(EXTRA_libguile_la_SOURCES): Removed threads.c.
	(noinst_HEADERS): Added coop-pthreads.c.
	(modinclude_HEADERS): Added coop-pthreads.h.

	* __scm.h (USE_THREADS, GUILE_ISELECT): Define when
	SCM_DEBUG_DEPRECATED.  Removed their use thru-out Guile.

	* iselect.c: Include "_scm.h" before testing HAVE_UNISTD_H.
	Thanks to Bill Schottstaedt!

	* numbers.c (scm_integer_expt): Make 0^z == 0 for z != 0.

	* _scm.h (HAVE_RESTARTABLE_SYSCALLS): Do define even when
	SCM_COPT_THREADS is defined.

2002-07-25  Marius Vollmer  <marius.vollmer@uni-dortmund.de>

	* random.c (rstate_free): Return zero.

2002-07-24  Dirk Herrmann  <D.Herrmann@tu-bs.de>

	* environments.c (remove_key_from_alist):  Removed.

	(obarray_remove):  Simplified.

2002-07-24  Stefan Jahn  <stefan@lkcc.org>

	* continuations.h: ia64: Include <signal.h> before 
	<sys/ucontext.h>.

2002-07-21  Dirk Herrmann  <D.Herrmann@tu-bs.de>

	* modules.c (scm_sym2var):  Don't compare SCM values with ==.

2002-07-21  Han-Wen Nienhuys <hanwen@cs.uu.nl>

	* goops.c (scm_compute_applicable_methods): use
	scm_remember_upto_here_1 iso scm_remember_upto_here

	* macros.c: include deprecation.h

	* vectors.c (scm_vector_move_right_x): remove side effect in
	macro arg.
	(scm_vector_move_left_x): idem.

	* net_db.c, posix.c, socket.c: variable naming: change ans to
	result.

	* sort.c (scm_merge_vector_x): accept vector as argument
	iso. SCM*. This is needed for full GC correctness.

	* gc.h: undo previous undocumented changes related to #ifdef
	GENGC.

2002-07-20  Han-Wen Nienhuys <hanwen@cs.uu.nl>

	* *.c: add space after commas everywhere.

	* *.c: use SCM_VECTOR_SET everywhere, where a vector is written.
	Document cases where SCM_WRITABLE_VELTS() is used.
	
	* vectors.h (SCM_VELTS): prepare for write barrier, and let
	SCM_VELTS() return a const pointer
	(SCM_VECTOR_SET): add macro.

2002-07-15  Dirk Herrmann  <D.Herrmann@tu-bs.de>

	* eval.c (SCM_CEVAL), macros.c (macro_print, scm_makmacro,
	scm_sym_macro, scm_macro_type), macros.h (scm_makmacro):
	Deprecated the special kind of built-in dynamic syntax transformer
	that was inaccurately named "macro".  Note:  The built-in syntax
	transformers that are named "mmacro" or "memoizing-macro" still
	exist, and it is these which come much closer to what one would
	call a macro.

2002-07-13  Neil Jerram  <neil@ossau.uklinux.net>

	* eval.c (unmemocopy): Fix for
	1001-local-eval-error-backtrace-segfaults (unmemoization crash
	with internal definitions and local-eval).

2002-07-12  Gary Houston  <ghouston@arglist.com>

	* dynl.c: Don't define stub procedures if DYNAMIC_LINKING is not
	defined.  They don't do anything useful, especially since the
	only case where DYNAMIC_LINKING is undefined seems to be
	when --with-modules=no is given to configure, which is basically
	requesting that the "dynamic linking module" be omitted.

	* Makefile.am (libguile_la_SOURCES): move dynl.c from
	libguile_la_SOURCES to EXTRA_libguile_la_SOURCES.

	* extensions.c (load_extension): check DYNAMIC_LINKING for
	scm_dynamic_call.
	* init.c (scm_init_guile_1): check DYNAMIC_LINKING for
	scm_init_dynamic_linking.

2002-07-10  Marius Vollmer  <mvo@zagadka.ping.de>

	* guile.c, iselect.h, net_db.c, posix.c, socket.c: No need to
	check for Cygwin when including <winsock2.h>, this is already
	check for by configure.  Thus, revert change from 2002-07-07.

2002-07-10  Gary Houston  <ghouston@arglist.com>

	* eq.c: include <string.h>
	* dynl.c: docstring editing.

2002-07-09  Gary Houston  <ghouston@arglist.com>

	* dynl.c (scm_dynamic_call): docstring editing.

2002-07-08  Rob Browning  <rlb@defaultvalue.org>

	* gc_os_dep.c: HURD fixes.

2002-07-07  Marius Vollmer  <mvo@zagadka.ping.de>

	Crosscompiling and Cygwin fixes by Jan Nieuwenhuizen.  Thanks!

	* Makefile.am: Override default rule for c-tokenize.$(OBJECT);
	this should be compiled for BUILD host.
	Override default rule for
	guile_filter_doc_snarfage$(EEXECT); this should run on BUILD host.
	Add missing $(EXEEXT) to guile_filter_doc_snarfage invocation.
	(snarf2checkedtexi): Use GUILE_FOR_BUILD instead of preinstguile.

	* guile.c, iselect.h, net_db.c, posix.c, socket.c: Do not include
	<winsock2.h> on Cygwin even when we have it.

2002-07-01  Dirk Herrmann  <D.Herrmann@tu-bs.de>

	* __scm.h (SCM_CAUTIOUS), eval.c (scm_eval_args, deval_args,
	SCM_CEVAL):  Removed compile time option SCM_CAUTIOUS to clean up
	the code.  Full number of arguments checking of closures is
	mandatory now.  However, the option to disable the checking has
	most probably not been used anyway.

2002-06-30  Dirk Herrmann  <D.Herrmann@tu-bs.de>

	* __scm.h (SCM_RECKLESS), backtrace.c (SCM_ASSERT), debug.c
	(scm_debug_options), eval.c (scm_lookupcar, scm_lookupcar1,
	scm_badargsp, SCM_CEVAL, SCM_APPLY, scm_map, scm_for_each),
	feature.c (scm_init_feature), gsubr.c (scm_gsubr_apply), numbers.c
	(scm_logand, scm_logior, scm_logxor, scm_i_dbl2big), srcprop.c
	(scm_source_properties, scm_set_source_properties_x,
	scm_source_property):  Removed compile time option SCM_RECKLESS to
	clean up the code.  Full number of arguments checking of closures
	is mandatory now.  However, the option to disable the checking has
	most probably not been used anyway.

	* srcprop.c (scm_source_properties, scm_set_source_properties_x,
	scm_source_property): Use !SCM_CONSP instead of SCM_NCONSP.

2002-06-30  Gary Houston  <ghouston@arglist.com>

	* dynl.c: Removed all SCM_DEFER_INTS/SCM_ALLOW_INTS, which won't
	do anything useful.  Added a comment about need for a mutex if
	pre-emptive threading is supported.

	* posix.c (scm_convert_exec_args), dynl.c
	(scm_make_argv_from_stringlist): static procs: 1) renamed both to
	allocate_string_pointers.  2) simplified: don't reallocate the
	strings, just make an array of pointers 3) avoid memory leaks on
	error 4) let the procedure report errors in its own name.
	Consequences: 1) the procedures now assume that SCM strings are
	nul-terminated, which should always be the case.  2) Since strings
	are not reallocated, it's now possible for strings passed to
	dynamic-args-call to be mutated.

2002-06-28  Dirk Herrmann  <D.Herrmann@tu-bs.de>

	* __scm.h, eval.c, eval.h:  Removed compile time option
	MEMOIZE_LOCALS to clean up the code.  Now, caching of local
	variable positions during memoization is mandatory.  However, the
	option to disable the caching has most probably not been used
	anyway.

2002-06-18  Marius Vollmer  <mvo@zagadka.ping.de>

	* print.c (scm_simple_format): Print missing part of format before
	~% control.  Thanks to Daniel Skarda!

2002-06-01  Marius Vollmer  <mvo@zagadka.ping.de>

	* mkstemp.c: Added exception notice to license statement.

2002-05-22  Marius Vollmer  <mvo@zagadka.ping.de>

	* numbers.c (mem2ureal): When returning an inexact zero, make sure
	it is represented as a floating point value so that we can change
	its sign.

        From John W. Eaton  <jwe@bevo.che.wisc.edu>

	* numbers.c (idbl2str): Don't omit sign when printing negative zero.

2002-05-14  Thien-Thi Nguyen  <ttn@giblet.glug.org>

	* gc_os_dep.c: For I386/OPENBSD, allow for `__i386__'
	in addition to `i386'.  Thanks to Dale P. Smith.

2002-05-08  Marius Vollmer  <mvo@zagadka.ping.de>

	* eq.c (real_eqv): New.
	(scm_eqv_p): Use it when comparing reals and complexes.

	* numbers.c: Include <string.h>, for strncmp.
	(mem2complex): Do not create negative NaNs.
	(scm_leq_p, scm_geq_p): Explicitely return #f when comparing a
	NaN.
	(scm_inexact_to_exact): Signal error when converting a NaN.

2002-05-06  Marius Vollmer  <mvo@zagadka.ping.de>

	* posix.c (scm_putenv): Handle removing variables explicitely by
	calling unsetenv.

	From John W. Eaton.

	* numbers.h: Conditionally include floatingpoint.h, ieeefp.h, and
	nan.h.	Provide declarations for scm_inf_p, scm_nan_p, scn_inf,
	and scm_nan.
	* numbers.c: [SCO && ! HAVE_ISNAN] (isnan): New function.
	[SCO && ! HAVE_ISINF] (isinf): New function.
	(xisinf, xisnan): New functions.
	(IS_INF): Delete.
	(isfinite): Define in terms of xisinf.
	(scm_inf_p, scm_nan_p): New functions.
	(guile_Inf, guile_NaN): New file-scope vars.
	(guile_ieee_init): New function.
	(scm_inf, scm_nan): New functions.
	(idbl2str): Handle Inf and NaN.	Remove funny label and
	corresponding gotos.
	(ALLOW_DIVIDE_BY_ZERO): New macro.
	(scm_divide): Allow division by zero to occur if
	ALLOW_DIVIDE_BY_ZERO is defined.
	Handle bignums and ints as special cases.

	Additional stuff by me:

	numbers.c (mem2ureal): Recognize "inf.0" and "nan.xxx".
	(scm_even_p, scm_odd_p): Treat infinity as even and odd.
	(iflo2str): Don't output a '+' for negative numbers or for Inf and
	NaN.  They will provide their own sign.
	(scm_divide): Only allow divides by inexact zeros.  Dividing by
	exact zeros still signals an errors.

2002-04-22  Thien-Thi Nguyen  <ttn@giblet.glug.org>

	* goops.h (scm_slot_exists_p): Rename from scm_slots_exists_p.
	* goops.c (scm_slot_exists_p): Rename from scm_slots_exists_p.
	(scm_slot_exists_p): Rename from scm_slots_exists_p.
	Thanks to Andreas Rottmann.

2002-04-20  Gary Houston  <ghouston@arglist.com>

	* removal of unused fields in root state (thanks to Christopher
	Cramer for pointing out the disuse.)
	* root.h (scm_root_state): removed def_inp, def_outp, def_errp.
	(scm_def_inp, scm_def_outp, scm_def_errp): removed.

	* root.c (root_mark): don't mark them.
	(scm_make_root): don't set them to #f.
	* init.c (scm_init_standard_ports): don't initialise with the
	default ports.

2002-04-17  Marius Vollmer  <mvo@zagadka.ping.de>

	* Makefile.am (EXTRA_DIST): Added cpp_err_symbols.c and
	cpp_sig_symbols.c.

2002-04-16  Marius Vollmer  <mvo@zagadka.ping.de>

	* guile-snarf.in: Do not clean input file.  This would write to
	the $(srcdir) during a VPATH build, which is not allowed.  It also
	isn't needed since it only works when an output filename has been
	specified and in that case we don't need to clean the input file
	because the output file will already exist.

2002-03-31  Marius Vollmer  <mvo@zagadka.ping.de>

	* guile-snarf: Install the trap for removing $cleanfile only when
	the value of $cleanfile is actually known.

2002-04-10  Rob Browning  <rlb@defaultvalue.org>

	* .cvsignore: add versiondat.h and *.c.clean.c.

2002-03-26  Dirk Herrmann  <D.Herrmann@tu-bs.de>

	* srcprop.[ch] (scm_c_source_property_breakpoint_p):  New
	function, replaces macro SRCBRKP.

	(SRCBRKP):  Deprecated.

	* eval.c (SCM_CEVAL): Replaced use of SRCBRKP by call to
	scm_c_source_property_breakpoint_p.  Removed some use of arg1 as
	temporary variable.

2002-03-25  Dirk Herrmann  <D.Herrmann@tu-bs.de>

	* debug.h, eval.c: Deprecated CHECK_ENTRY, CHECK_APPLY and
	CHECK_EXIT and removed all references to them.

2002-03-24  Dirk Herrmann  <D.Herrmann@tu-bs.de>

	* debug.h (scm_ready_p, debug_print): Removed declarations.

	* eval.c (EVALCELLCAR): Removed.

	(SCM_CEVAL): Eliminated label loopnoap.  Removed side-effecting
	operation from condition.

2002-03-24  Marius Vollmer  <mvo@zagadka.ping.de>

	* guile-snarf.in: When the output filename is "-", write to
	stdout.  When no "-o" option is given, use "-" as the output
	filename (i.e., stdout).  Only 'clean' the inputfile or remove the
	output file on error when the output file name is not "-".  Define
	the preprocessor macro SCM_MAGIC_SNARFER while snarfing.

	* Makefile.am (.c.x): Pass "-o $@" to guile-snarf.

2002-03-23  Dirk Herrmann  <D.Herrmann@tu-bs.de>

	* eval.c (SCM_CEVAL, SCM_APPLY): Eliminated labels wrongnumargs
	and the corresponding goto statements.  Removed redundant code.

2002-03-20  Dirk Herrmann  <D.Herrmann@tu-bs.de>

	* eval.c (SIDEVAL): Removed.

	(SCM_CEVAL): Minimized scope of variable orig_sym.  Eliminated
	goto-labels cdrxnoap, cdrxbegin and nontoplevel_cdrxnoap.  Changed
	argument checking order for set! to locals, variables and symbols.
	Improvements to control structure.  Removed some uses of arg1 and
	arg2 as temporary variables.

2002-03-15  Thien-Thi Nguyen  <ttn@giblet.glug.org>

	* guile-snarf.in: Remove "--compat=1.4" support.
	Add "-d" and "-D" support.

	(deprecated_list): New var.
	(compat_mode_clean_xxx): Delete.
	(grep_deprecated): New func.
	("main"): If "-d" or "-D", call `grep_deprecated'.

2002-03-15  Neil Jerram  <neil@ossau.uklinux.net>

	* hooks.h: Change scm_t_c_hookype_t everywhere to
	scm_t_c_hook_type.

	Docstring fixes:

	* strings.c (scm_string_p): Change unnecessary `iff' to `if'.

	* ports.c (scm_sys_make_void_port): Use `@file'.

	* numbers.c (scm_number_p, scm_real_p): Use `otherwise' rather
	than `else'.

	* macros.c (scm_makmacro): Don't say that the form replaces its
	source, because it doesn't.
	(scm_makmmacro): Clarify difference between this and scm_makmacro.

	* backtrace.c (scm_display_error), filesys.c (scm_umask,
	scm_select, scm_basename), goops.c (scm_method_generic_function),
	numbers.c (scm_integer_length), posix.c (scm_getgroups, scm_execl,
	scm_setlocale, scm_flock), socket.c (scm_shutdown): Correct
	spelling mistakes.

	* debug.c (scm_debug_options), eval.c
	(scm_eval_options_interface), read.c (scm_read_options): Change
	incorrect @var in docstring to @code.

2002-03-14  Marius Vollmer  <mvo@zagadka.ping.de>

	* unif.c (singp): Use SCM_REALP instead of SCM_SLOPPY_REALP.

	* snarf.h (SCM_SNARF_INIT): Add "^:^" after code so that
	guile-snarf can remove trailing non-init code.

	* guile-snarf.in (modern_snarf): Remove everything following and
	including "^:^" from the output.

2002-03-14  Dirk Herrmann  <D.Herrmann@tu-bs.de>

2002-03-13  Dirk Herrmann  <D.Herrmann@tu-bs.de>

	* eval.c (SCM_CEVAL): Got rid of the last reference to t.lloc.
	The next step will be to remove the union 't' and simplify the
	code of SCM_CEVAL that way.

	* iselect.c (collisionp, gnfds, greadfds, gwritefds, gexceptfds,
	rreadfds, rwritefds, rexceptfds): Made static.

	* gc.c (terminating), fports.c (terminating): Renamed
	scm_i_terminating.

2002-03-11  Marius Vollmer  <mvo@zagadka.ping.de>

	* numbers.c (scm_divide): Adapt code from libstdc++/f2c to void
	potential overflow problems.  Thanks to John W Eaton!

	* strop.c (string_capitalize_x): Treat characters as unsigned so
	that 8-bit chars work.  Thanks to David Pirotte!

2002-03-10  Dirk Herrmann  <D.Herrmann@tu-bs.de>

	* eval.c (SCM_CEVAL): Cleaned up the handling of 'slot-ref',
	'slot-set!' and 'nil-cond'.  Removed some uses of t.arg1, arg2 and
	proc as temporary variables.  Introduced temporary variables with
	hopefully descriptive names for clarification.  Replaced SCM_N?IMP
	by a more explicit predicate in some places.

2002-03-09  Dirk Herrmann  <D.Herrmann@tu-bs.de>

	* eval.c (SCM_CEVAL): Cleaned up the handling of #@dispatch.
	Added lots of comments regarding the implementation of #@dispatch.
	Changed intra-procedure communication to use t.arg1 instead of
	arg2.  Removed some uses of t.arg1, t.lloc and proc as temporary
	variables.  Introduced temporary variables with hopefully
	descriptive names for clarification.  Replaced SCM_N?IMP by a more
	explicit predicate in some places.  Use SCM_INSTANCE_HASH instead
	of computing the expression explicitly.  Eliminate now unused
	label nontoplevel_cdrxbegin.

	* goops.h (SCM_INSTANCE_HASH): New macro.

	* objects.h (SCM_CMETHOD_FORMALS, SCM_CMETHOD_BODY): New macros.

2002-03-08  Thien-Thi Nguyen  <ttn@giblet.glug.org>

	* Makefile.am (bin_SCRIPTS): Revive this decl, w/ initial element
	"guile-snarf" moved back from `noinst_SCRIPTS'.

2002-03-08  Neil Jerram  <neil@ossau.uklinux.net>

	* srcprop.c (scm_set_source_property_x): If SRCPROPS obj already
	exists when adding a source property other than those that are
	handled explicitly, add the new property to the SRCPROPS obj's
	plist.

	* debug.h (SCM_MAX_FRAME_SIZE): Remove incorrect comment about use
	of SCM_MAX_FRAME_SIZE as a bit mask; it isn't used like this.

	* eval.c (SCM_CEVAL): Don't store scm_debug_eframe_size in
	debug.status.  It isn't needed, and it can overflow the bits
	reserved for it (which may lead to a segv or a GC abort).

2002-03-02  Dirk Herrmann  <D.Herrmann@tu-bs.de>

	* eval.c (SCM_CEVAL): Cleaned up the handling of 'apply'.  Removed
	side-effecting operations from conditions and macro calls.
	Replaced SCM_N?IMP by a more explicit predicate in some places.
	Minimized the scope of some variables.

2002-03-02  Stefan Jahn  <stefan@lkcc.org>

	failed if their sizes were different.

2002-03-02  Dirk Herrmann  <D.Herrmann@tu-bs.de>

	'letrec' and 'set*': Removed some uses of t.arg1, t.lloc and proc
	as temporary variables.  Removed side-effecting operations from
	conditions and macro calls.  Introduced temporary variables with
	hopefully descriptive names for clarification.  Replaced SCM_N?IMP
	by a more explicit predicate in some places.  Removed code that
	was conditionally compiled if SICP was defined - which it never
	is.

2002-03-02  Dirk Herrmann  <D.Herrmann@tu-bs.de>

	* eval.c (SCM_CEVAL): Cleaned up the handling of 'cons' and 'do':
	Removed some uses of t.arg1 and proc as temporary variables.

	Introduced temporary variables with hopefully descriptive names
	for clarification.  Replaced SCM_N?IMP by a more explicit
	predicate in some places.

	frequency.  Avoided some unnecessary tail-recursion calls.

2002-03-01  Dirk Herrmann  <D.Herrmann@tu-bs.de>

	* gc.c (SCM_HEAP_SEG_SIZE, CELL_UP, CELL_DN, NEXT_DATA_CELL,

	scm_object_property, scm_set_object_property_x): Remove invalid
	@deffnx lines for corresponding procedure property primitives.

	These changes add a @deffnx C function declaration and function
	index entries for each Guile primitive to the copy of the doc
	snarf output that is used for reference manual synchronization.
	Online help is unchanged.

	* snarf.h (SCM_SNARF_DOCS): Output primitive's C function name.
	(SCM_DEFINE, SCM_DEFINE1, SCM_REGISTER_PROC): Supply to C function
	name to SCM_SNARF_DOCS.

	* guile-snarf-docs-texi.in: Pass the shell script's arguments into
	snarf-check-and-output-texi.

	* Makefile.am (guile-procedures.texi): New rule.
	(BUILT_SOURCES, guile.texi, guile-procedures.txt, CLEANFILES):
	Changed so that the last stage of doc snarfing is now performed
	twice, once to produce guile-procedures.txt for online help, and
	once to produce guile.texi for reference manual synchronization.

2001-11-15  Dirk Herrmann  <D.Herrmann@tu-bs.de>

	* eval.c (RETURN):  Wrap in do{}while(0) in order to make it
	safely usable as a single statement followed by a ';', for example
	in an if statement.

	(SCM_CEVAL, SCM_APPLY):  Clean up code using 'RETURN'.

2001-11-13  Neil Jerram  <neil@ossau.uklinux.net>

	* random.c (scm_random_solid_sphere_x,
	scm_random_hollow_sphere_x): Correct "shere" typos.

	* hashtab.c (scm_hash_fold): Add missing apostrophe to docstring.

	* version.c (scm_version): Update docstring to include
	`micro-version'.

2001-11-13  Marius Vollmer  <mvo@zagadka.ping.de>

	* modules.c (scm_c_export): Call va_end after collecting the
	symbols.

	* strop.h, strop.c (scm_substring_move_left_x,
	scm_substring_move_right_x): Removed.

	* __scm.h (HAVE_UINTPTR_T, HAVE_PTRDIFF_T, HAVE_LONG_LONG,
	HAVE_LONG_LONGS): Define to "1" when defining them, to mirror what
	configure does.

2001-11-12  Marius Vollmer  <mvo@zagadka.ping.de>

	* numbers.c: Document macros to define when including
	num2integral.i.c.  MAX_VALUE and MIN_VALU are no longer used, we
	now rely on SIZEOF_ macros that have been figured out at
	configure time.

	* num2integral.i.c: Adapt to new interface.
	(NUM2INTEGRAL): Test whether a fixnum can be represented in the
	target type by casting it and checking whether it is still the
	same.  Do not try to handle bignums for integral types that are
	smaller than fixnums.  When handling bignums, collect the
	magnituse first into a unsigned type, and correctly check for
	overflow.
	(INTEGRAL2BIG): Do not use MIN_VALUE explicitely by observing that
	only -MIN_VALUE can still be negative of all negative numbers (in
	twos-complement).

	* tags.h (SIZEOF_SCM_T_BITS): Define it appropriately.

	* __scm.h: Define HAVE_UINTPTR_T, HAVE_PTRDIFF_T and
	HAVE_LONG_LONG depending on whether their size is non-zero.

2001-11-11  Thien-Thi Nguyen  <ttn@glug.org>

	* strop.c (scm_string_null_p): Docfix; nfc.
	Thanks to Scott Lenser.

2001-11-07  Neil Jerram  <neil@ossau.uklinux.net>

	* extensions.c (scm_load_extension): Canonicalize docstring
	whitespace.

	* unif.c (scm_uniform_array_write), ports.c
	(scm_current_output_port, scm_force_output), dynwind.c
	(scm_dynamic_wind), scmsigs.c (scm_setitimer, scm_getitimer),
	filesys.c (scm_open, scm_lstat), struct.c
	(scm_make_struct_layout), random.c (scm_random,
	scm_random_solid_sphere_x, scm_random_hollow_sphere_x, strop.c
	(scm_i_index): Remove superfluous whitespace from end of docstring
	lines.

	* filesys.c (scm_select), guardians.c (scm_guardian_greedy_p),
	strings.c (scm_make_string), variable.c (scm_make_variable,
	scm_make_undefined_variable, scm_variable_p, scm_variable_set_x,
	scm_variable_bound_p), scmsigs.c (scm_setitimer, scm_getitimer),
	posix.c (scm_crypt), struct.c (scm_make_vtable_vtable), hashtab.c
	(scm_hash_fold), ports.c (scm_port_for_each): Remove superfluous
	newline at end of docstrings.

	* modules.c (scm_set_current_module): Add missing newline to
	docstring.

2001-11-07  Stefan Jahn  <stefan@lkcc.org>

	* win32-socket.[ch]: New files.  Defines Winsock-API error codes
	and makes them available through Guile.  That is because the
	Winsock-API does not store its errors in `errno' and thus cannot
	return error messages via `strerror (errno)'.

	* socket.c (scm_init_socket): Initialize `win32-socket' part
	here under M$-Windows.

	* numbers.h: Added missing declaration of
	`scm_sys_check_number_conversions()'.

	* error.c: Local definition of SCM_I_STRERROR and SCM_I_ERRNO
	and use in `(strerror)' and `(system-error)'.

	* Makefile.am (EXTRA_libguile_la_SOURCES): Added
	`win32-socket.[ch]' to extra source and header files.

2001-11-06  Marius Vollmer  <mvo@zagadka.ping.de>

	* script.c (scm_shell_usage, scm_compile_shell_switches): Prepend
	a call to turn-on-debugging when --debug has been given instead of
	turning it on directly.  Also, handle new `--no-debug' option,
	which might suppress the call to turn-on-debugging.

2001-11-05  Stefan Jahn  <stefan@lkcc.org>

	* struct.c (s_scm_struct_vtable_p): Corrected docstring.

2001-11-04  Stefan Jahn  <stefan@lkcc.org>

	* Makefile.am (libguile_la_LIBADD): Added $(THREAD_LIBS_LOCAL)
	here (was at guile_LDADD) which describes the dependency
	correctly and allows a clean build on Win32.

	* __scm.h (SCM_API): Follow-up patch.  Renamed __FOO__ macros
	into FOO.

	* __scm.h: USE_DLL_IMPORT indicates the usage of the DLL
	import macros for external libraries (libcrypt, libqthreads,
	libreadline and libregex).

	* coop-defs.h: Include <winsock2.h> for `struct timeval'.

	* posix.c (flock): Added support for flock() in M$-Windows.

	* guile.c (SCM_IMPORT): Follow-up patch.  Use SCM_IMPORT instead
	of __SCM_IMPORT__.

	* fports.c (getflags): Differentiate reading and writing pipes
	descriptors.

	* filesys.c (S_IS*): Redefine all of the S_IS*() macros for
	M$-Windows.

	* coop.c (coop_condition_variable_timed_wait_mutex): Use
	conditionalized error code if `ETIMEDOUT' is not available.
	(scm_thread_usleep): Remove bogus declaration of `struct timeval
	timeout'.

	* numbers.c (PTRDIFF_MIN): Moved this definition where it actually
	belongs.  That is because NO_PREPRO_MAGIC gets undefined after
	each inclusion of `num2integral.i.c'.
	(SIZE_MAX): Define NO_PREPRO_MAGIC if SIZE_MAX is undefined.

2001-11-03  Marius Vollmer  <mvo@zagadka.ping.de>

	* eval.c (scm_m_begin): Allow `(begin)`, with no subforms.
	(SCM_CEVAL): Evaluate an empty `begin' to SCM_UNSPECIFIED.

2001-11-02  Mikael Djurfeldt  <mdj@linnaeus>

	* print.c (scm_iprin1): Mark print state as revealed when
	dispatching to generic write or display.

	* unif.c (scm_ra2contig): Fixed memory overwrite bug.

2001-11-02  Marius Vollmer  <mvo@zagadka.ping.de>

	Support for native Win32.  Thanks to Stefan Jahn!

        * Makefile.am: Add win32-uname.c, win32-uname.h, win32-dirent.c
	and win32-dirent.h to extra source and header files.  These
	include the uname() and the POSIX dirent interface implementation
	for M$-Windows.  Put `-no-undefined' into LDFLAGS to support
	linkers which do not allow unresolved symbols inside shared
	libraries.  Corrected `guile_filter_doc_snarfage$(EXEEXT)'
	dependency.

        * __scm.h: Defined SCM_API.  This macro gets prepended to all
        function and data definitions which should be exported or imported
        in the resulting dynamic link library in the Win32 port.

        * __scm.h, alist.h, arbiters.h, async.h, backtrace.h, boolean.h,
        chars.h, continuations.h, coop-defs.h, coop-threads.h,
        debug-malloc.h, debug.h, deprecation.h, dynl.h, dynwind.h,
        environments.h, eq.h, error.h, eval.h, evalext.h, extensions.h,
        feature.h, filesys.h, fluids.h, fports.h, gc.h, gdb_interface.h,
        gdbint.h, gh.h, goops.h, gsubr.h, guardians.h, hash.h, hashtab.h,
        hooks.h, init.h, ioext.h, iselect.h, keywords.h, lang.h, list.h,
        load.h, macros.h, mallocs.h, modules.h, net_db.h, numbers.h,
        objects.h, objprop.h, options.h, pairs.h, ports.h, posix.h, print.h,
        procprop.h, procs.h, properties.h, ramap.h, random.h, rdelim.h,
        read.h, regex-posix.h, root.h, rw.h, scmsigs.h, script.h, simpos.h,
        smob.h, socket.h, sort.h, srcprop.h, stackchk.h, stacks.h, stime.h,
        strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
        tags.h, threads.h, throw.h, unif.h, values.h, variable.h, vectors.h,
        vports.h, weaks.h:
        Prefixed each each exported symbol with SCM_API.

        * continuations.c: Added comment about the use of the extern
        declarations of {get,set}context() functions used in the ia64 port.

        * continuations.h, gc.c: `__libc_ia64_register_backing_store_base'
        is meant to be a `unsigned long *'.

        * filesys.c: Include `direct.h' if possible.  Use local
	`win32-dirent.h' for the native M$-Windows port.  Define S_IS*()
	macros for M$-Windows.  Implementation of `fstat_Win32()' which is
	able to differentiate between sockets and other file descriptors.
	Use this function as wrapper in `scm_fstat()'.  Fixed typo in
	`scm_dirname()'.

        * fports.c: Include `io.h' is possible.  Put `*fp' into referring
        statement block in `scm_fport_buffer_add()'.
        Some corrections in `getflags()'.

        * gdb_interface.h (GDB_INTERFACE): Also support __CYGWIN__.

        * guile.c: Make sure to define __SCM_IMPORT__ for shared library
        build on Win32.  Disable preloaded symbols on Win2 platforms.

        * ioext.c, ports.c: Include `io.h' is possible.

        * mkstemp.c: Include `process.h' is possible.

        * net_db.c: Disable extern declaration of `h_errno' for __CYGWIN__,
        too.
        Put `scm_return_entry()' into HAVE_GETSERVENT conditional.

        * posix.c: Remove unnecessary dirent includes and defines. Include
	local `win32-uname.h' for MinGW.  Extern declaration of
	`mkstemp()' for systems where it does not exists.  Make
	`getlogin()' available on M$-Windows.

        * scmsigs.c: Made `usleep()' avalable on MinGW.

        * stime.c: On M$-Windows `tzname[]' is known to be `_tzname[]'.

	* win32-dirent.c: Include "win32-dirent.h", not "dirent.h".

	* win32-uname.c: Include "win32-uname.h", not "uname.h".

2001-10-28  Mikael Djurfeldt  <mdj@linnaeus>

	* unif.c (scm_uniform_array_read_x, scm_uniform_array_write):
	Don't apply scm_uniform_vector_length on arrays.

2001-10-14  Dirk Herrmann  <D.Herrmann@tu-bs.de>

	* eval.c (scm_lookupcar, scm_m_letstar, scm_m_do, iqq,
	scm_m_define, scm_m_letrec1, scm_m_let, scm_m_expand_body,
	scm_macroexp, unmemocopy, scm_eval_args, scm_deval_args,
	SCM_CEVAL, scm_map, scm_init_eval):  When building lists, prefer
	scm_list_<n> over scm_cons[2]?.

	(scm_unmemocar, scm_m_cond, scm_m_letstar, scm_m_letrec1,
	scm_m_let, scm_m_atbind, unmemocopy, SCM_CEVAL, SCM_APPLY):  Use
	SCM_C[AD][AD]R instead of explicit form.

	(scm_m_set_x, scm_m_cond, scm_m_letstar, scm_m_do):  Reordered
	comparison parameters.

	(scm_m_case, scm_m_cond, scm_m_letstar, scm_m_do, SCM_CEVAL):  Use
	!SCM_NULLP instead of SCM_NIMP.

	(scm_m_case):  Don't copy the form.  Renamed proc to clause and
	minimized its scope.  Renamed x to clauses.  Removed side
	effecting operation from macro call.

	(scm_m_cond):  Don't copy the form.  Renamed arg1 to clause and
	minimized its scope.  Renamed x to clauses.  Minimized the scope
	of variable 'len'.  Make sure the else clause is treated specially
	even in case of '=>' occurences.  Don't change the else to #t in
	order to be able to distinguish this case in the evaluator.  Leave
	type checking of the recipient to the evaluator.

	(scm_c_improper_memq):  Made the comment somewhat clearer.

	(scm_m_lambda):  Renamed proc to formals.  Removed unnecessary
	test for SCM_IM_LET at the place of the formal parameters.
	Simplified the formal parameter checking.

	(scm_m_letstar):  Added Comment.  Renamed proc to bindings.
	Renamed arg1 to binding and minimized its scope.  Eliminated
	unnecessary consing.

	(scm_m_do):  Renamed proc to bindings.  Minimized the scope of
	variable 'len'.

	(build_binding_list):  New static function.

	(unmemocopy):  Don't use SCM_TYP7 on pairs (it's unclean).
	Further, split up the 'letrec' unmemoizing code to the
	corresponding parts for 'do', 'let' and 'letrec', adding comments
	to each form.  Cleanup the handling of the do form (This removes
	some *real* code :-).

	(SCM_CEVAL):  Removed side effecting operation from macro call.
	Handle the 'else clause of the 'cond form specially - the symbol
	'else is not replaced with #t any more.

2001-10-14  Gary Houston  <ghouston@arglist.com>

	* version.c (scm_version): use sprintf instead of snprintf,
	for portability.  thanks to Bill Schottstaedt.

2001-10-14  Mikael Djurfeldt  <mdj@linnaeus>

	* read.c (scm_lreadr): When user-defined hash procedure returns
	SCM_UNSPECIFIED: Fall back to standard handling instead of raising
	an exception.  (This prevents parsing of uniform vectors from
	interfering with parsing of numbers.)

2001-10-13  Marius Vollmer  <mvo@zagadka.ping.de>

	* numbers.c: Set NO_PREPRO_MAGIC when defining our version of
	PTRDIFF_MIN.  Thanks to Ken Raeburn.

2001-10-07  Marius Vollmer  <mvo@zagadka.ping.de>

	* Makefile.am (EXTRA_libguile_la_SOURCES): Added "mkstemp.c".

	* eval.c (scm_m_atbind): First try to find the variable without
	defining it locally; when it has not been found, define it
	locally.

	* modules.c (module_variable): Pass over variables that exist but
	are unbound.

2001-10-06  Marius Vollmer  <mvo@zagadka.ping.de>

	* backtrace.c (display_backtrace_file_and_line): Only use
	scm_basename when POSIX support is compiled in.  Thanks to Chris
	Cramer.

2001-10-13  Dirk Herrmann  <D.Herrmann@tu-bs.de>

	* numbers.c (mem2uinteger):  Return number read so far when coming
	across a hexdigit after having read a # or if not reading a hex
	value.  This will enable the calling code to correctly handle
	forms like 1e2.  (The background is, that the exponent markers d,
	e and f are also hexdigits.)  Thanks to Mikael Djurfeldt for
	providing this patch.

	(mem2complex):  Fix erroneous double-negation.  Now, numbers like
	1-i will be read correctly.

2001-10-12  Mikael Djurfeldt  <mdj@linnaeus>

	* debug.c (scm_mem_to_proc): Fixed typo in previous change.

	* validate.h (SCM_VALIDATE_DOUBLE_DEF_COPY): New macro.

2001-10-12  Dirk Herrmann  <D.Herrmann@tu-bs.de>

	* print.c (scm_print_state_vtable, print_state_pool):
	Initialize.  These variables are now registered as gc roots.

	(scm_current_pstate):  Update documentation.

	(scm_current_pstate, scm_make_print_state, scm_free_print_state,
	scm_prin1, scm_init_print):  print_state_pool is registered as a
	gc root and thus does not need to be protected by a surrounding
	pair any more.

	(make_print_state):  The car of print_state_pool no longer holds
	the scm_print_state_vtable.

	(scm_current_pstate, scm_make_print_state, print_circref,
	scm_iprin1, scm_prin1, scm_iprlist):  Prefer !SCM_<foo> over
	SCM_N<foo>.

	(scm_prin1):  When building lists, prefer scm_list_<n> over
	scm_cons[2]?.

	(scm_iprlist):  Removed a redundant SCM_IMP test.

	(scm_simple_format):  Use SCM_EQ_P to compare SCM values.

2001-10-11  Dirk Herrmann  <D.Herrmann@tu-bs.de>

	* debug.c (scm_make_iloc):  Prefer !SCM_<foo> over SCM_N<foo>.

	(scm_memcons, scm_mem_to_proc):  When building lists, prefer
	scm_list_<n> over scm_cons[2]?.

	(scm_mem_to_proc):  Prefer SCM_CONSP over SCM_NIMP.

	(scm_procedure_name):  Use SCM_CADR instead of explicit form.

	(debugobj_print):  Coerce scm_intprint arg 1 to long, not int.
	Thanks to Rob Browning for the patch (see log entry 2001-09-21) -
	for some reason his patch didn't make it into the cvs.

2001-10-09  Dirk Herrmann  <D.Herrmann@tu-bs.de>

	* numbers.c (mem2decimal_from_point):  Cleaned up the parsing a
	little bit - should even be somewhat more accurate now.

2001-10-08  Rob Browning  <rlb@defaultvalue.org>

	* gc.c: support ia64 register backing store.
	(SCM_MARK_BACKING_STORE): new macro.

	* continuations.h: support ia64 register backing store.
	(struct scm_t_contregs): add ia64 register backing store.

	* continuations.c: support ia64 register backing store.
	(continuation_mark): mark ia64 register backing store.
	(continuation_free): free ia64 register backing store.
	(scm_make_continuation): capture ia64 register backing store.
	(copy_stack_and_call): copy ia64 register backing store.

2001-10-08  Dirk Herrmann  <D.Herrmann@tu-bs.de>

	* hashtab.c (scm_hash_fn_create_handle_x):  The result of assoc_fn
	is known to be #f if no entry is found.  Thus, use !SCM_FALSEP
	instead of SCM_NIMP to test for that case.

	* strings.h (SCM_SET_STRING_LENGTH):  Cast the length to
	scm_t_bits instead of long.

2001-10-06  Marius Vollmer  <mvo@zagadka.ping.de>

	* tags.h (SCM_T_BITS_MAX, SCM_T_SIGNED_BITS_MAX,
	SCM_T_SIGNED_BITS_MIN): New.
	* numbers.h (SCM_MOST_POSITIVE_FIXNUM, SCM_MOST_NEGATIVE_FIXNUM):
	Use them to make these macros computable by the preprocessor.

	* num2integral.i.c (INTEGRAL2NUM): Let the preprocessor test
	whether the integral type fits in a fixnum, not the compiler.
	This removes a spurious compiler warning.  Also, honor the
	NO_PREPRO_MAGIC flag to suppress any preprocessor tests.  This is
	needed for `long long's.

	* numbers.c: Define NO_PREPRO_MAGOC when including
	num2integral.c.i for `long long' and `signed long long'.

2001-10-06  Mikael Djurfeldt  <mdj@linnaeus>

	These changes fixes a race condition in the Guile coop - pthread
	compatibility code.

	* coop.c (mother_awake_p): New variable.
	(coop_create): Set mother_awake_p before creating or signalling
	mother; wait until mother is going to sleep before returning.
	(mother): Reset mother_awake_p before going to sleep.

2001-10-05  Dirk Herrmann  <D.Herrmann@tu-bs.de>

	* options.c (protected_objects, scm_init_options):  The content of
	protected_objects is now protected from garbage collection using
	scm_gc_register_root instead of scm_permanent_object.

	(get_option_setting):  New static function that	computes an option
	setting as it was formerly done in the function scm_options.

	(get_documented_option_setting):  New static function that
	returns option documentation as it was formerly done in the
	function scm_options.  Note that documentation C strings are no
	longer precomputed into SCM objects.  Instead, they are converted
	into SCM strings every time get_documented_option_setting is
	called.

	(change_option_setting):  New static functions that modifies the
	option setting as it was formerly done in the function
	scm_options.  The function is now exception safe, i. e. won't
	cause a memory leak when interrupted.  Further, only non-immediate
	option values are added to the protection list.

	(scm_options):  This function now has only the purpose to dispatch
	to to get_option_setting, get_documented_option_setting or
	change_option_setting, depending on the arguments given to
	scm_options.

	(scm_init_opts):  Don't convert documentation C strings into SCM
	strings.  Further, don't protect any object values:  They _must_
	be immediate values, otherwise there is no guarantee that they
	have not been collected before anyway.

	* options.[ch] (scm_t_option):  Made type unsigned, name into a
	constant char* and val into a scm_t_bits type.

	(scm_options, scm_init_opts):  The number of options is guaranteed
	to be larger or equal to zero.  Thus, the type is changed to
	unsigned.

2001-10-05  Dirk Herrmann  <D.Herrmann@tu-bs.de>

	* num2integral.i.c (NUM2INTEGRAL):  Eliminated some warnings about
	testing an unsigned value for being >= 0.

2001-10-05  Dirk Herrmann  <D.Herrmann@tu-bs.de>

	* numbers.h:  Removed old comment about using SCM_CAR to access
	non-pair cells.

	(SCM_MOST_POSITIVE_FIXNUM, SCM_MOST_NEGATIVE_FIXNUM):  Make sure
	the return value is signed.  Thanks to Brian Crowder for the bug
	report.

	(SCM_SRS):  Avoid unnecessary casting and don't unpack input
	values.  With this patch, SCM_SRS can be safely used for other
	types than scm_t_signed_bits.  However, it should still better be
	an internal macro and thus be renamed to SCM_I_SRS.

	(SCM_MAKINUM, SCM_INUM):  Use proper casting.

2001-10-03  Gary Houston  <ghouston@arglist.com>

	* continuations.h, unif.h: in the descriptions of the bit patterns
	of the heap cells, make bit 0 the least significant.

2001-09-25  Thien-Thi Nguyen  <ttn@glug.org>

	* chars.h (SCM_MAKE_CHAR): Use `scm_t_bits' instead of `intptr_t'.
	Thanks to Golubev I. N.

2001-09-25  Gary Houston  <ghouston@arglist.com>

	* ports.c (scm_drain_input): extended the docstring.  thanks to
	Alex Schroeder and Thien-Thi Nguyen.

2001-09-23  Mikael Djurfeldt  <mdj@linnaeus>

	* validate.h (SCM_NUM2FLOAT, SCM_NUM2DOUBLE,
	SCM_VALIDATE_FLOAT_COPY, SCM_VALIDATE_DOUBLE_COPY): New
	macros. (The NUM names might soon change.)

	* numbers.h: Added missing declarations.

2001-09-22  Mikael Djurfeldt  <mdj@linnaeus>

	* Makefile.am: Distribute num2float.i.c.

	* num2float.i.c: New file, multiply included by numbers.c, used
	to "templatize" the float <-> num conversion routines.

	* numbers.c: New functions: scm_num2float, scm_float2num,
	scm_num2double, scm_double2num.

2001-09-21  Rob Browning  <rlb@defaultvalue.org>

	* .cvsignore: really add version.h

	* strings.h (SCM_SET_STRING_LENGTH): coerce "l" to a long.
	Otherwise it fails on the alpha.  However, we might rather choose
	this size conditionally.

	* numbers.c (scm_gcd): change "k" to a long from an int.
	Otherwise it fails on the alpha.  However, we might rather choose
	this size conditionally.

	* error.c (scm_wta): coerce char* to intptr_t before int
	assignment.

	* debug.c (debugobj_print): coerce scm_intprint arg 1 to long, not
	int.

	* chars.h (SCM_MAKE_CHAR): coerce value to intptr_t.

2001-09-20  Mikael Djurfeldt  <mdj@linnaeus>

	* numbers.c (scm_integer_expt): Accept inexact integer in second
	argument.  (Thanks to Bill Schottstaedt.)

2001-09-20  Rob Browning  <rlb@defaultvalue.org>

	* .cvsignore: add version.h

	* versiondat.h.in: removed (obsolete).

	* version.h.in: renamed from version.h.
	(SCM_GUILE_MAJOR_VERSION): new public macro.
	(SCM_GUILE_MINOR_VERSION): new public macro.
	(SCM_GUILE_MICRO_VERSION): new public macro.

	* version.h: renamed to version.h.in.

	* version.c
	(scm_major_version): support integer *_VERSION macros.
	(scm_minor_version): support integer *_VERSION macros.
	(scm_micro_version): support integer *_VERSION macros.
	(scm_version): support integer *_VERSION macros.

2001-09-20  Mikael Djurfeldt  <mdj@linnaeus>

	* error.c, error.h: Made error keys globally accessible.
	Applications might want to test for these or use them in a direct
	call to scm_error.

	* num2integral.i.c (NUM2INTEGRAL): Report an error when these
	routines are passed an inexact.  This change in behavior is
	motivated by concordance with R5RS: It is more common that a
	primitive doesn't want to accept an inexact for an exact.

2001-09-17  Dirk Herrmann  <D.Herrmann@tu-bs.de>

        The following patch partially undoes my patch from 2001-06-30,
	where I added the function scm_gc_mark_cell_conservatively.  The
	function is buggy, since it breaks guile during conservative
	marking if a pointer on the stack points directly into the list of
	free cells on the heap:  With conservative cell marking this will
	cause the whole free list to be scanned and marked - boom!

	* gc.c (allocated_mark, MARK, heap_segment,
	scm_gc_mark_cell_conservatively, scm_init_storage), gc.h
	(scm_gc_mark_cell_conservatively):  Remove function
	scm_gc_mark_cell_conservatively and update the corresponding
	comments and uses accordingly.  Thanks to Christopher Cramer for
	the patch.  (Minor corrections by me.)

2001-09-15  Gary Houston  <ghouston@arglist.com>

	* root.h (scm_root_state): removed the continuation_stack and
	continuation_stack_ptr members, which have no apparent purpose.
	(scm_continuation_stack, scm_continuation_stack_ptr): #defines
	removed.

	* root.c (root_mark), init.c (restart_stack, start_stack), gc
	(scm_igc): remove all references to contination_stack and
	continuation_stack_ptr, avoiding allocation of a vector and
	useless processing during gc.

2001-09-13  Dirk Herrmann  <D.Herrmann@tu-bs.de>

	* guardians.c (tconc_t, t_tconc):  Renamed tconc_t to t_tconc.

	(guardians_t, t_guardians):  Renamed guardians_t to t_guardians.

	(GUARDIAN, GUARDIAN_DATA):  Renamed GUARDIAN to GUARDIAN_DATA.

	(guardian_apply, scm_get_one_zombie, scm_make_guardian,
	mark_and_zombify):  Prefer !SCM_<foo> over SCM_N<foo>.

2001-09-13  Dirk Herrmann  <D.Herrmann@tu-bs.de>

	* guardians.c (mark_dependencies_in_tconc,
	whine_about_self_centered_zombies, scm_init_guardians):  Register
	the static global variable `self_centered_zombies' via
	scm_gc_register_root, to make some cdr-ing unnecessary.

2001-09-13  Dirk Herrmann  <D.Herrmann@tu-bs.de>

	* backtrace.c (display_backtrace_file,
	display_backtrace_file_and_line):  Use SCM_EQ_P when comparing SCM
	values, use SCM_FALSEP when comparing SCM values against #f.
	Thanks to Rob Browning for the bug report.

2001-09-12  Martin Baulig  <martin@home-of-linux.org>

	* strings.[ch] (scm_str2string): New function.

	(scm_must_realloc): Likewise.

2001-09-01  Michael Livshin  <mlivshin@bigfoot.com>

	* numbers.c (scm_sys_check_number_conversions): new function,
	defined if Guile is compiled in debugging mode.  currently checks
	`scm_num2ulong', should check much much more.

	* num2integral.i.c (NUM2INTEGRAL): when converting a bignum to
	unsigned, ensure that it's positive.  thanks to Martin Baulig!

	* list.c (SCM_I_CONS):  Make sure the cell type is initialized

	conservatively.

	(scm_mark_locations, scm_cellp):  Extracted the search for the

	the result of SCM_WVECT_GC_CHAIN.

	(scm_gc_sweep):  Weak vectors don't have extra fields any more.

	* weaks.c (allocate_weak_vector):  New static function.  It does
	not patch any previously created vector object during the
	construction of a weak vector, and thus doesn't need to switch
	off interrupts during vector creation.

	(scm_make_weak_vector, scm_make_weak_key_hash_table,
	scm_make_weak_value_hash_table, scm_make_doubly_weak_hash_table):

	user-defined hash procedure first, so that overriding the builtin
	hash characters is possible (this was needed for implementing
	SRFI-4's read synax `f32(...)').

	* num2integral.i.c: Use scm_t_signed_bits instead of scm_t_bits,
	because the latter is unsigned now and breaks comparisons like
	(n < (scm_t_signed_bits)MIN_VALUE).

2001-06-26  Neil Jerram  <neil@ossau.uklinux.net>

	* eval.h, eval.c (scm_call_4): New function.

2001-05-24  Michael Livshin  <mlivshin@bigfoot.com>

	The purpose of this set of changes is to regularize Guile's usage
	of ANSI C integral types, with the following ideas in mind:

	- SCM does not nesessarily have to be long.
	- long is not nesessarily enough to store pointers.
	- long is not nesessarily the same size as int.

	The changes are incomplete and possibly buggy.  Please test on
	something exotic.

2001-04-01  Dirk Herrmann  <D.Herrmann@tu-bs.de>

	* gc.c (MARK):  Re-introduce a cheap sanity test for non debug
	mode, as suggested by Michael Livshin.

2001-03-31  Michael Livshin  <mlivshin@bigfoot.com>

	* backtrace.c (display_backtrace_body): since the `print_state'
	variable is not used (instead its data field is used directly as
	`pstate'), protect it from the hungry compiler optimizations.
	thanks to Bill Schottstaedt for the report.

2001-03-30  Dirk Herrmann  <D.Herrmann@tu-bs.de>

	* gc.[ch] (scm_tc16_allocated):  New type tag for allocated cells.
	It is only defined and used if guile is compiled with
	SCM_DEBUG_CELL_ACCESSES set to true.  It's purpose is, to never
	let cells with a free_cell type tag be visible outside of the
	garbage collector when in debug mode.

	* gc.c (scm_debug_cell_accesses_p):  Set to true as default.

	(scm_assert_cell_valid):  Use a local static variable to avoid
	recursion.

	(MARK):  Only check for rogue cell pointers in debug mode.  Use
	scm_cellp for this purpose and place all checks for rogue pointers
	into that function.  Further, since due to conservative scanning
	we may encounter free cells during marking, don't use the standard
	cell type accessor macro to determine the cell type.

	(scm_cellp):  Check if the cell pointer actually points into a
	card header.

	(scm_init_gc):  Initalize scm_tc16_allocated.

	* gc.h (GCH):  Renamed to SCM_GC_H.

	(SCM_VALIDATE_CELL):  Enclose the expression in brackets.  This
	might be unnecessary, but I feel better this way :-)

	(SCM_GC_CELL_TYPE):  New macro.

	(SCM_SETAND_CDR, SCM_SETOR_CDR):  Deprecated.  These are not used
	in guile, and it is unlikely that they will be applied to real
	pairs anyway.

	(SCM_SET_FREE_CELL_TYPE):  Removed.  It was not used.

	(SCM_GC_SET_ALLOCATED):  New macro.  Only non-empty if guile is
	compiled with SCM_DEBUG_CELL_ACCESSES set to true.

	(SCM_NEWCELL, SCM_NEWCELL2):  Use of SCM_GC_SET_ALLOCATED will
	make sure that in debug mode no free cell will ever be visible
	outside of the garbage collector.

2001-03-30  Dirk Herrmann  <D.Herrmann@tu-bs.de>

	* async.c (scm_asyncs_pending):  Don't use != to compare SCM
	values.

	* async.c (scm_system_async), variable.c (scm_make_variable,
	scm_make_undefined_variable):  Use scm_cons to create a pair.

	* debug.c (scm_reverse_lookup):  Perform proper type checking.
	Remove suspicious use of SCM_SLOPPY_CONSP.

	* eq.c (scm_equal_p), tags.h (SCM_ECONSP):  Use SCM_CONSP instead
	of SCM_SLOPPY_CONSP.  A sane compiler should be able to perform
	the corresponding optimization.

	* eval.c (iqq):  Use proper type check.

	(scm_m_expand_body):  Remove redundant type checks.

	(promise_print):  Don't access promise cells as pairs.

	scm_deval_args SCM_CEVAL), guardians.c (scm_guard), hashtab.c
	(scm_internal_hash_fold), print.c (scm_iprlist):  Use !SCM_CELLP
	for SCM_NCELLP, !SCM_CONSP for SCM_NCONSP, !SCM_IMP for SCM_NIMP,
	!SCM_FALSEP for SCM_NFALSEP, !SCM_NULLP for SCM_NNULLP

	* eval.c (scm_m_define, scm_macroexp, SCM_CEVAL), print.c
	(scm_iprin1):  Use new macro predicate and accessors.

	* eval.h (scm_tc16_macro):  Removed declaration.  It is declared
	in macros.h.

	* eval.h (EVALH), macros.h (MACROSH), ports.h (PORTSH), procs.h
	(PROCSH), tags.h (TAGSH), variable.h (VARIABLEH):  Renamed to
	SCM_EVAL_H, SCM_MACROS_H, SCM_PORTS_H, SCM_PROCS_H, SCM_TAGS_H and
	SCM_VARIABLE_H.  Even the macros that are used to inhibit
	including a header file twice should be in the SCM_ namespace.

	* fluids.c (scm_swap_fluids, scm_swap_fluids_reverse),
	properties.c (scm_primitive_property_ref,
	scm_primitive_property_del_x):  Prefer stronger predicates like
	SCM_NULLP or SCM_FALSEP over SCM_IMP.

	* gc.c (MARK):  Use proper macros to access procedure-with-setter
	cell elements and closure cell elements.

	(gc_sweep_freelist_finish, scm_gc_sweep, init_heap_seg):  Don't
	access free cells as pairs.

	(scm_unprotect_object):  scm_hashq_get_handle returns #f if
	no hashtab entry is found.

	* gc.c (scm_gc_sweep), ports.c (scm_close_port):  Use new macro
	SCM_CLR_PORT_OPEN_FLAG.

	* guardians.c (TCONC_IN), print.c (scm_free_print_state):  Don't
	use SCM_SET_C[AD]R for uninitialized cells.

	* hashtab.c (scm_hash_fn_get_handle):  Use SCM_VALIDATE_VECTOR.
	If the hashtable has no slots, return #f instead of '().  This
	unifies the return value with most assoc-functions.

	(scm_hash_fn_ref):  Use proper type check.

	(scm_hashq_get_handle, scm_hashv_get_handle, scm_hash_get_handle):
	Removed references to non-existing functions from documentation.

	* keywords.c (scm_keyword_dash_symbol):  Use proper macros to
	access keyword cell elements.

	* macros.h (SCM_MACROP, SCM_MACRO_TYPE, SCM_MACRO_CODE):  New
	macros.

	* ports.h (SCM_CLR_PORT_OPEN_FLAG):  New macro.

	* print.c (scm_iprlist):  Added comment.  Improved loop
	conditions.

	elements.

	(scm_variable_bound_p):  Don't use SCM_NEGATE_BOOL.

	* variable.h (SCM_VARVCELL):  Don't access variable cells as
	pairs.

	added FIXME comment, removed register specifier.

	(scm_string_capitalize): Rewrote and corrected docstrings.

	* gh.h/gh_data.c (gh_ints2scm):  Changed the signature to use a
	const int* to reflect that the input array of integers remains
	unchanged.  Thanks to Brett Viren for the hint.

2001-03-14  Martin Grabmueller  <mgrabmue@cs.tu-berlin.de>

	* gh_data.c (gh_scm2chars, gh_scm2shorts, gh_scm2longs),

	in various places.
	(gh_scm2newstr, gh_symbol2newstr): Change call to
	scm_must_malloc() to malloc(), because user-free()able memory is
	allocated.

	misc-errors.

	* macros.h (SCM_ASSYNT):  On assertion failure, issue a misc-error

2001-03-08  Neil Jerram  <neil@ossau.uklinux.net>

2001-03-08  Mikael Djurfeldt  <mdj@linnaeus.mit.edu>

	* ramap.c (racp): Removed optimization which caused array copying
	to fail if the two arrays shared storage.  Re-inserted the IVDEP
	macros removed in the change of 2000-03-09.  (Don't really have a

	on Crays.  This needs testing!)  Thanks to Miroslav Silovic.

2001-03-07  Mikael Djurfeldt  <mdj@linnaeus.mit.edu>

2001-03-06  Dirk Herrmann  <D.Herrmann@tu-bs.de>

	* coop-threads.c (scm_call_with_new_thread), load.c
	(scm_primitive_load, scm_sys_search_load_path), random.c

	(potentially) issue a scm-misc-error or wrong-num-args error
	message.

	* load.c (scm_search_path):  Use SCM_ASSERT_TYPE to give details
	about the expected type with the wrong-type-arg error message.

	* smob.c (scm_make_smob):  Abort on misuse of smob - it indicates

2001-03-05  Mikael Djurfeldt  <mdj@linnaeus.mit.edu>

	* eval.c (scm_m_letstar): Removed check for duplicate bindings.
	Duplicate bindings are OK in a let* since a let* is semantically

2001-03-05  Martin Grabmueller  <mgrabmue@cs.tu-berlin.de>

	* print.c (scm_print_options): Fixed texinfo in docstring.

	taking an unexpectedly large filename for an AF_UNIX socket from
	bind/connect/sendto (thanks to Martin Grabmueller).

	* socket.c (scm_sock_fd_to_port, SCM_SOCK_FD_TO_PORT): removed the
	former and adjusted the latter.
	(scm_socket, scm_socketpair): cosmetic changes.
	(scm_getsockopt, scm_setsockopt): declare optlen as int, not
	size_t as socklen_t substitute.  don't restrict args/return values
	to INUM: allow full range of int or size_t.
	(scm_fill_sockaddr): check arguments before allocating memory, to
	avoid leakage.  use malloc, not scm_must_malloc.
	(scm_connect, scm_bind, scm_sendto): use int, not size_t as socklen_t
	substitute.  free the sockaddr structure before throwing an error.
	(scm_init_add_buffer): procedure removed, together with its static
	buffer scm_addr_buffer, which wouldn't be thread safe.  instead,
	define a macro MAX_ADDR_SIZE and declare the buffer where needed.
	(scm_accept, scm_getpeername, scm_getsockname, scm_recvfrom,
	scm_sendto): use a local buffer instead of scm_addr_buffer.
	adjust for new SCM_SOCK_FD_TO_PORT.  use int for address size,
	not size_t.
	(scm_recvfrom): set addr->sa_family to AF_UNSPEC before the recvfrom
	call to detect whether recvfrom could be bothered to set the address.
	(scm_init_socket): don't call scm_init_addr_buffer.

2001-03-04  Dirk Herrmann  <D.Herrmann@tu-bs.de>

	* validate.h (SCM_WTA, RETURN_SCM_WTA):  Deprecated.

2001-03-04  Mikael Djurfeldt  <mdj@linnaeus.mit.edu>

	in the non-toplevel loop.
	(nontoplevel_cdrxnoap, nontoplevel_cdrxbegin, nontoplevel_begin):
	New labels with the meaning of their non-"nontoplevel" partners,
	but they are used when it is known that the body is not evaluated at
	top-level.

	reporting for empty combinations.

	* eval.c (scm_ceval, scm_deval): When evaluating expressions on

	* symbols.c (scm_mem2symbol): Put a empty statement after the
	next_symbol label.  This is mandated by ANSI, appearantly.

2001-02-13  Marius Vollmer  <marius.vollmer@uni-dortmund.de>

	* gc_os_dep.c: Do not include <linux/version.h>.  It makes no
	sense to compile for a specific kernel version.  Do not include
	<asm/signal.h> while defining __KERNEL__.  This hack should no
	longer be needed and caused problems.

2001-02-13  Marius Vollmer  <mvo@zagadka.ping.de>

	* eval.c (scm_ceval, scm_deval): use `SIDEVAL' instead of
	SCM_CEVAL when evaluating subforms of `begin' forms.  SCM_CEVAL
	can not deal with immediates.

2001-02-12  Keisuke Nishida  <kxn30@po.cwru.edu>

	* list.c (scm_list_copy): Validate the first argument.

2001-02-11  Marius Vollmer  <mvo@zagadka.ping.de>

	function.

	* eval.h (scm_primitive_eval, scm_primitive_eval_x): New
	prototypes.
	(scm_i_eval, scm_i_eval_x, scm_eval, scm_eval_x): Changed argument
	names to better reflect their meaning.

	* eval.c (scm_ceval, scm_deval): Recognize when `begin' is being
	evaluated at top-level and synronize lookup closure before
	executing every subform.
	(scm_primitve_eval_x, scm_primitive_eval): New functions.
	(scm_eval_x, scm_eval): Reimplement in terms of
	scm_primitive_eval_x and scm_primitive_eval, respectively.

2001-02-09  Marius Vollmer  <mvo@zagadka.ping.de>

	* macros.c (scm_macro_name, scm_macro_transformer): Use
	SCM_SMOB_DATA instead of SCM_CDR.  Provided by Martin Grabmueller.

	and C names.
	(scm_select_module, scm_set_current_module): Likewise.  Changed
	all uses.

	* ports.c (scm_port_for_each): Make a snapshot of the port table
	before iterating over it.  The table might change while the user
	code is running.  With the snapshot, the user can depend on the
	fact that each port that existed at the start of the iteration is
	encountered exactly once.  (ice-9 popen) depends on this.

2001-02-08  Dirk Herrmann  <D.Herrmann@tu-bs.de>

	* strings.h (SCM_STRING_MAX_LENGTH):  New macro.

	* strings.c (scm_makstr, scm_take_str, scm_make_string):  Added
	range checking for the size parameter.  Thanks to Martin
	Grabmueller for the hint.
