in lib:

	* addext.c, backupfile.c, fsusage.c, human.c, pathmax.h,
	rpmatch.c, userspec.c, xreadlink.c, xstrtol.c: Include <limits.h>
	without checking for HAVE_LIMITS_H.
	* backupfile.c, fsusage.c, hash.c, human.c, safe-read.c, userspec.c,
	xstrtol.c (CHAR_BIT) : Don't define, since <limits.h> is guaranteed
	to do that.
	* fatal.c: Include <stdarg.h> without checking for __STDC__.
	* exclude.c: Include <stdbool.h> unconditionally.
	* tempname.c: Include <stddef.h> unconditionally.
	* hash.c: Include <limits.h>, since we no longer define CHAR_BIT.
	* modechange.c, rpmatch.c (NULL): Don't define, since
	<stddef.h> does that.
	* quote.c: Dont include <stddef.h> or <sys/types.h>; not needed.
	* safe-read.c (INT_MAX): Don't define, since <limits.h> does that.
	* safe-read.c (TYPE_MINIMUM, TYPE_MAXIMUM): Remove; no longer needed.
	* xstrtol.c: Likewise.
	* safe-read.c: Remove TYPE_SIGNED; no longer needed.
	* savedir.c: Include <stddef.h> instead of defining NULL.

in m4:

	* backupfile.m4 (gl_BACKUPFILE): Don't check for limits.h.
	* fsusage.m4 (gl_PREREQ_FSUSAGE_EXTRA): Likewise.
	* human.m4 (gl_HUMAN): Likewise.
	* pathmax.m4 (gl_PATHMAX): Likewise.
	* rpmatch.m4 (gl_FUNC_RPMATCH): Likewise.
	* userspec.m4 (gl_USERSPEC): Likewise.
	* xreadlink.m4 (gl_XREADLINK): Likewise.
	* m4/xstrtol.m4 (gl_PREREQ_XSTRTOL): Likewise.
	* quote.m4 (gl_QUOTE): Don't check for stddef.h.
