	* hooks.c (scm_create_hook): deprecated.
	(make_hook): deleted.
	(scm_make_hook): all the hook creation code is now here.

	* gc.c (scm_init_gc): don't call `scm_create_hook'.  instead make
	a hook, make it permanent, and do a `scm_c_define' on it.

2001-05-26  Dirk Herrmann  <D.Herrmann@tu-bs.de>

	* __scm.h (SCM_DEBUG_TYPING_STRICTNESS):  Make 1 the default.

	* eval.c (promise_print):  Read the promise's value as an object.

	(SCM_CEVAL):  Don't perform side-effecting operations in macro
	parameters.

	* eval.h (SCM_EVALIM2):  Fix the typing strictness of the
	conditional expression.

	* gc.c (scm_master_freelist, scm_master_freelist2):  Added missing
	initializer.

	* gh_data.c (gh_set_substr):  Removed redundant unsigned >= 0
	text, removed redundant computation of effective_length and fixed
	the overflow check.

	* goops.c (test_slot_existence):  Use SCM_EQ_P to compare SCM
	values.

	(wrap_init):  Don't use SCM_C[AD]R for non pairs.

	(hell):  Make it a scm_bits_t pointer rather than a SCM pointer.

	* goops.c (scm_sys_modify_class), strports.c (st_resize_port),
	struct.h (SCM_SET_STRUCT_PRINTER):  Store unpacked values.

	* goops.h (SCM_ACCESSORS_OF, SCM_SLOT):  Return a SCM value.

	Read SCM objects rather than scm_bits_t values.

	* tags.h (SCM_VOIDP_TEST):  Removed.

	(SCM_DEBUG_TYPING_STRICTNESS):  Now takes values 0, 1, 2.  The
	value of 2 now corresponds to the former 1, the current 1
	corresponds to the former situation that SCM_VOIDP_TEST was
	defined.

	(SCM):  Now defined as typedef struct scm_unused_struct * SCM; 
	If this appears to be not ANSI compliant, we will change it to 
	typedef struct scm_unused_struct { } * SCM;
	Thanks to Han-Wen Nienhuys for the suggestion.

	--disable-deprecated.

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.

	Merged from mvo-vcell-cleanup-1-branch.

	The concept of vcells has been removed from Guile.  With it,
	explicit obarrays and associated operations are gone.  Use
	hashtables instead of obarrays.

	result as variable instead of vcell.  Glocs no longer point to a
	vcell but to a variable.  Use scm_c_define instead of
	scm_sysintern and treat the result as a variable (which it is),
	not a vcell.

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.

	* eval.c (EVALCAR, iqq, scm_m_expand_body, scm_eval_args,
	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.

	pairs.

	scm_variable_set_x):  Use proper macros to access variable cell
	elements.

	(scm_variable_bound_p):  Don't use SCM_NEGATE_BOOL.

	* variable.h (SCM_VARVCELL):  Don't access variable cells as
	pairs.

	* vectors.c (scm_vector), weaks.c (scm_weak_vector):  Simplified,
	added FIXME comment, removed register specifier.

2001-03-29  Keisuke Nishida  <kxn30@po.cwru.edu>

	* goops.c, goops.h (scm_init_oop_goops_goopscore_module): Deprecated.
	* init.c (scm_init_guile_1): Don't init goopscore module.

2001-03-27  Marius Vollmer  <mvo@zagadka.ping.de>

	* eval.c (SCM_APPLY): Check that arg1 is bound for scm_tc7_cxr.

2001-03-27  Martin Grabmueller  <mgrabmue@cs.tu-berlin.de>

	(scm_string_upcase_x, scm_string_upcase, scm_string_downcase_x),
	(scm_string_downcase, scm_string_capitalize_x),
	(scm_string_capitalize): Rewrote and corrected docstrings.

	(scm_mkstemp): new procedure implementing "mkstemp!".
	* posix.h: declare scm_mkstemp.

	* net_db.c: declare h_errno if configure didn't define HAVE_H_ERRNO.

2001-03-08  Mikael Djurfeldt  <mdj@linnaeus.mit.edu>

	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

	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>

	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

	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.

	in the non-toplevel loop.
	(nontoplevel_cdrxnoap, nontoplevel_cdrxbegin, nontoplevel_begin):
	New labels with the meaning of their non-"nontoplevel" partners,

	reporting for empty combinations.

	* eval.c (scm_ceval, scm_deval): When evaluating expressions on

2001-02-13  Marius Vollmer  <mvo@zagadka.ping.de>

	* eval.c (scm_ceval, scm_deval): use `SIDEVAL' instead of

	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

	* numbers.h (SCM_CHAR_BIT, SCM_LONG_BIT):  Moved to __scm.h.

	(SCM_FIXNUM_BIT, SCM_MOST_POSITIVE_FIXNUM,
	SCM_MOST_NEGATIVE_FIXNUM):  Moved here from __scm.h.

2001-01-17  Dirk Herrmann  <D.Herrmann@tu-bs.de>

	* __scm.h (SCM_FIXNUM_BIT):  Added.  The name is chosen in analogy
	to the names in limits.h.

	* numbers.c (abs_most_negative_fixnum):  Added.

	(scm_quotient, scm_remainder):  Fixed the fixnum-min / (abs
	fixnum-min) special case.

	(scm_big_and):  Fix for negative first parameter.

	(scm_bit_extract):  Fix for fixnum paramters.
	Thanks to Rob Browning for the bug report.

	(scm_init_numbers):  Initialize abs_most_negative_fixnum.

2001-01-16  Dirk Herrmann  <D.Herrmann@tu-bs.de>

	* symbols.c (scm_symbol_bound_p):  Fixed comment.
	Thanks to Chris Cramer.

	* smob.[ch] (scm_make_smob_type):  Return type is scm_bits_t now.
	Thanks to Bill Schottstaedt.

2001-01-11  Michael Livshin  <mlivshin@bigfoot.com>

	from Matthias K�ppe:

	* objects.h (SCM_SET_ENTITY_SETTER): new macro.  SCM_ENTITY_SETTER
	casts its result, so doesn't yield an lvalue per ANSI C.

	* goops.c (s_scm_sys_set_object_setter_x): use
	SCM_SET_ENTITY_SETTER.
	(clear_method_cache): use SCM_SET_ENTITY_PROCEDURE.

	* gc.h (SCM_GC_SET_CARD_BVEC): new macro.  SCM_GC_CARD_BVEC casts
	its result, so doesn't yield an lvalue per ANSI C.
	(SCM_GC_SET_CARD_FLAGS): ditto for SCM_GC_GET_CARD_FLAGS.
	(SCM_GC_CLR_CARD_FLAGS): redefined in terms of
	SCM_GC_SET_CARD_FLAGS.
	(SCM_GC_SET_CARD_FLAG, SCM_GC_CLR_CARD_FLAGS): ditto.

	* gc.c (INIT_CARD): use the explicit setter macro to set the bvec.

2001-01-08  Gary Houston  <ghouston@arglist.com>

	* validate.h (SCM_VALIDATE_SUBSTRING_SPEC_COPY): new macro.
	* ioext.c (scm_read_string_x_partial, scm_read_delimited_x),
	socket.c (scm_recvfrom): use the new macro, plus minor docstring
	changes.
	* ioext.c (scm_read_string_x_partial): don't crash if -1 is supplied
	for fdes.  if current input port is used, check that it's a file
	port.

2001-01-06  Gary Houston  <ghouston@arglist.com>

	* ioext.c (scm_read_string_x_partial): new procedure, implements
	read-string!/partial.
	* ports.c (scm_take_from_input_buffers): new procedure used by
	scm_read_string_x_partial.
	(scm_drain_input): use scm_take_from_input_buffers.

2001-01-06  Marius Vollmer  <mvo@zagadka.ping.de>

	* validate.h (SCM_VALIDATE_NUMBER): New.

2001-01-03  Michael Livshin  <mlivshin@bigfoot.com>

	* guardians.c (F_GREEDY, F_LISTED, F_DESTROYED, GREEDY_P,
 	SET_GREEDY, LISTED_P, SET_LISTED, CLR_LISTED, DESTROYED_P,
 	SET_DESTROYED): new defines/macros.
	(GUARDIAN_LIVE, GUARDIAN_ZOMBIES, GUARDIAN_NEXT): deleted.
	(add_to_live_list): takes a `guardian_t *' now, not SCM.
	(guardian_print): print more info.
	(guardian_apply): check if the guardian is destroyed, and throw an
 	error if so.  take one more optional argument `throw_p'.
	(scm_guard): depending on the value of `throw_p', return a boolean
 	result.
	(scm_get_one_zombie): remove redundant property test.
	(guardian_t): represent the various (currently 3, I hope nothing
 	more gets added) boolean fields as bit flags.
	(scm_guardian_destroyed_p, scm_guardian_greedy_p): new predicates.
	(scm_destroy_guardian_x): new procedure.

	* guardians.h: added prototypes for `scm_guardian_greedy_p' and
	`scm_guardian_destroyed_p'.  changed prototype for `scm_guard'.

2001-01-01  Gary Houston  <ghouston@arglist.com>

	* fports.c (fport_write): bugfix: handle short writes for
	unbuffered ports too.  optimize the buffered case by minimizing
	the number of write/flush calls.
	(write_all): new helper procedure.
