Remove src/m/*.
* configure.in: Remove all mention of src/m/*. (machine, machfile, M_FILE, config_machfile, and_machfile): Remove. All uses removed. (BITS_PER_CHAR, BITS_PER_SHORT, BITS_PER_INT, BITS_PER_LONG) (BITS_PER_LONG_LONG): Move to src/lisp.h. * lib/makefile.w32-in: Remove dependencies on $(EMACS_ROOT)/src/m/intel386.h. * make-dist: Don't make links to src/m. * admin/CPP-DEFINES: Do not mention src/m/*.h. (BITS_PER_EMACS_INT, BITS_PER_LONG, BITS_PER_CHAR) (BITS_PER_SHORT, BITS_PER_INT): Remove. * admin/MAINTAINERS: Remove src/m/. * lib-src/makefile.w32-in: Remove dependencies on $(EMACS_ROOT)/src/m/intel386.h. * msdos/mainmake.v2 (TAGS tags): Don't look at $(CURDIR)/src/m/intel386.h. * nt/config.nt: Do not include "m/intel386.h"; file was removed. (BITS_PER_CHAR, BITS_PER_SHORT, BITS_PER_INT, BITS_PER_LONG): Move to src/lisp.h. (EMACS_INT_MAX): New macro. This directory predates autoconf and is no longer needed nowadays. Move its few remaining bits of functionality to where they're needed. * src/m/README, src/m/alpha.h, src/m/amdx86-64.h, src/m/ia64.h, src/m/ibmrs6000.h: * src/m/ibms390x.h, src/m/intel386.h, src/m/m68k.h, src/m/macppc.h: * src/m/sparc.h, src/m/template.h: Remove. * src/Makefile.in (M_FILE): Remove. All uses removed. * src/alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): * src/lisp.h (USE_LSB_TAG): * src/mem-limits.h (EXCEEDS_LISP_PTR): Use VAL_MAX, not VALBITS, in #if. * src/lisp.h (EMACS_INT_MAX): New macro, useful in #if. (EMACS_UINT): Define unconditionally now. (BITS_PER_CHAR, BITS_PER_SHORT, BITS_PER_INT, BITS_PER_LONG) (BITS_PER_EMACS_INT): New constants, replacing what used to be in config.h, but not useful in #if. (GCTYPEBITS, VALBITS): Define unconditionally, since m/* files don't define them any more. (VAL_MAX): New macro. (VALMASK): Use it. * src/puresize.h (PURESIZE_RATIO): Use EMACS_INT_MAX, not BITS_PER_EMACS_INT, in #if. * src/s/aix4-2.h (BROKEN_FIONREAD, BROKEN_SIGAIO, BROKEN_SIGPTY) (BROKEN_SIGPOLL): Move here from m/ibmrs6000.h, which was removed. * src/s/gnu-linux.h (ULIMIT_BREAK_VALUE) [__i386__]: * src/s/ms-w32.h (DATA_START): Move here from removed file m/intel386.h. * src/s/gnu.h (NLIST_STRUCT): Remove undef; 'configure' does this. * src/s/irix6-5.h (_LP64): Remove; lisp.h no longer needs this.
