Paul Eggert 3437465030 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.
