changelog

制作2.6内核的CLFS时 使用的diffutils-2.8.7.tar.gz包

	* lib/c-stack.h (siginfo_t, c_stack_die): Remove decl.

	* lib/file-type.c, lib/file-type.h: New files.  These contain code
	that was in src/diff.c, but is now librarified and spiffed up a
	bit.  Jim Meyering suggested this.

	* lib/fnmatch.c (alloca, __builtin_expect): Define for non-GCC hosts.
	<strings.h>: Include only if HAVE_STRINGS_H.
	<stddef.h>: Include if we include stdlib.h.
	Do not comment out all code if ! HAVE_FNMATCH_GNU.
	(getenv): Do not declare if HAVE_DECL_GETENV.
	(__strchrnul, __wcschrnul): Remove; not used.
	(MEMPCPY): Use mempcpy if not _LIBC; use memcpy if neither _LIBC
	nor HAVE_MEMPCPY.
	(FOLD) [HANDLE_MULTIBYTE]: Do not pass wide char to ISUPPER.
	(STRLEN, STRCAT, MEMPCPY) [HANDLE_MULTIBYTE && !defined _LIBC]:
	Use wcslen rather than __wcslen, and likewise for wcscat, wmempcpy.
	(MEMPCPY) [HANDLE_MULTIBYTE]: Use wmempcpy if not _LIBC; use wmemcpy
	if neither _LIBC nor HAVE_WMEMPCPY.
	* lib/fnmatch_.h (__const): Do not define to empty, as this breaks
	Sun cc.  The code doesn't work with K&R anyway.
	* lib/fnmatch_loop.c (struct patternlist.str): Size 1, not 0,
	as C89 requires this.
	(NEW_PATTERN): Use offsetof, not sizeof, since str now has size 1.
	* lib/fnmatch_.h: Import from glibc fnmatch.h.
	* lib/fnmatch.c, lib/fnmatch_loop.c: Import from glibc.

	* lib/posixver.c: Include posixver.h.

	* lib/regex_.h: Renamed from lib/regex.hin.

	* m4/c-stack.m4 (jm_PREREQ_C_STACK): Do not AC_REQUIRE
	jm_AC_TYPE_UINTMAX_T and do not use uintmax_t.
	Check for sys/resource.h, uccontext.h.
	Check for decls and existence of getcontext, sigaltstack.
	Check for stack_t.

	* m4/codeset.m4, m4/glibc21.m4, m4/lcmessage.m4: Remove.

	* m4/fnmatch.m4: Update to latest Autoconf CVS for AC_FUNC_FNMATCH_GNU.

	* m4/mbstate_t.m4 (AC_TYPE_MBSTATE_T): Renamed from AC_MBSTATE_T.
	All uses changed.  Upgrade to recent Autoconf CVS.

	* m4/stdbool.m4 (AC_HEADER_STDBOOL): Do not cast pointer to
	bool in integer constant expression; C99 does not allow it.
	Reported by Bruno Haible.

	* po/LINGUAS: Add hu, pt_BR.
	* po/hu.po, po/pt_BR.po: New files.

	* src/Makefile.am (noinst_HEADERS): Remove diff.h.

	* src/io.c (find_and_hash_each_line): Likewise.

	* src/diff.h (TAB_WIDTH): Remove.
	(tabsize): New decl.
	(sdiff_half_width, sdiff_column2_offset): Now size_t rather than
	unsigned int.

	* src/diff3.c (skipwhite, readnum): New functions.
	(process_diff_control): Use them.
	(SKIPWHITE, READNUM): Remove.
	(read_diff): Don't worry about errno == ENOEXEC.

	K&R.
	(TABSIZE_OPTION): New constant.
	(longopts, usage, main): New option --tabsize=COLUMNS.
	(cleanup): New arg signo.  All uses changed.
	(ck_editor_status, main, edit): Don't worry about ENOEXEC.

	Include limits.h.
	(SIZE_MAX, SSIZE_MAX): Define if standard headers don't.
	(MIN): New macro.
	(block_read): Do not attempt to read more than SSIZE_MAX bytes, as the
