Mon Apr 1 13:34:55 1996 Roland McGrath <roland@whiz-bang.gnu.ai.mit.edu>cvs/libc-960403

	* stdio-common/tst-printf.c (main): Add new test case.

	* sysdeps/generic/setenv.c (unsetenv): Use old-style definition.

Mon Apr  1 11:39:10  Ulrich Drepper  <drepper@gnu.ai.mit.edu>

	* stdlib/strtod.c (STRTOD): Fix handling of American style FP
	numbers.

	* stdio-common/vfprintf.c (vfprintf): Don't increment format
	string pointer twice after seeing `*'.

Sun Mar 31 17:31:54 1996  Roland McGrath  <roland@whiz-bang.gnu.ai.mit.edu>

	* MakeTAGS (po/SYS_libc.pot): Prepend header processed from
 	po/header.pot.

Sun Mar 31 18:07:32 1996  Ulrich Drepper  <drepper@gnu.ai.mit.edu>

	* locale/Makefile (others, install-bin): Compiling locale works
        again.
	(locale-modules): locale has no --dump option anymore.  Remove
	ctypedump.

	* locale/programs/config.h: Don't declare euidaccess.
	Use #include_next to get libc's config.h.

	* locale/programs/ctypedump.c: Not needed anymore.  Dump option
	of locale is removed.

	* locale/programs/locale.c: Adapt for new locale implementation.

	* stdio-common/_itoa.h (_itoa_word): Define as inline function.
	* stdio-common/_itoa.c (_itoa_lower_digits, _itoa_upper_digits):
	Don't declare static because used in _itoa_word inline function.

	* stdio-common/printf-parse.h: Prepare for use in wide-char
	stdio implementation.
	(find_spec): Take additional argument to work with mbrlen instead
	of mblen.
	(parse_one_spec): Ditto.

	* stdio-common/printf-prs.c: Prepare for use in wide-char
	stdio implementation.

	* stdio-common/printf.h: Mark change for wide-char handling.
	Changing it now would result in incompatibilities.

	* stdio-common/vfprintf.c: New and fast implementation.

	* wcsmbs/Makefile (routines): Remove pre-ISO C multibyte functions
	mbsadvance, mbscat, mbschr, mbscmp, mbscpy, mbsdup, mbslen,
	mbsncat, mbsncmp, mbsncpy, mbsrchr, mbstomb.
	Change wcswcs to wcsstr.
	Add wmemchr, wmemcmp, wmemcpy, wmemmove, wmemset, btowc, wctob,
	mbsinit, mbrlen, mbrtowc, wcrtomb, mbsrtowcs, wcsrtombs.

	* wcsmbs/btowc.c, wcsmbs/mbrlen.c, wcsmbs/mbrtowc.c,
        wcsmbs/mbsinit.c, wcsmbs/mbsrtowcs.c, wcsmbs/wchar.h,
        wcsmbs/wcrtomb.c, wcsmbs/wcsrtombs.c, wcsmbs/wcsstr.c,
        wcsmbs/wctob.c, wcsmbs/wmemchr.c, wcsmbs/wmemcmp.c,
        wcsmbs/wmemcpy.c, wcsmbs/wmemmove.c, wcsmbs/wmemset.c: New
        function according to ISO C amendment 1.
	* wchar.h: Wrapper around "wcsmbs/wchar.h".

	* wcsmbs/wcscat.c, wcsmbs/wcschr.c, wcsmbs/wcscmp.c,
        wcsmbs/wcscpy.c, wcsmbs/wcscspn.c, wcsmbs/wcsdup.c,
        wcsmbs/wcslen.c, wcsmbs/wcsncat.c, wcsmbs/wcsncmp.c,
        wcsmbs/wcsncpy.c, wcsmbs/wcspbrk.c, wcsmbs/wcsrchr.c,
        wcsmbs/wcsspn.c, wcsmbs/wcstok.c: Changed to conform with ISO C
        amendment 1.

	* wcsmbs/mbsadvance.c, wcsmbs/mbscat.c, wcsmbs/mbschr.c,
        wcsmbs/mbscmp.c, wcsmbs/mbscpy.c, wcsmbs/mbsdup.c,
        wcsmbs/mbslen.c, wcsmbs/mbsncat.c, wcsmbs/mbsncmp.c,
        wcsmbs/mbsncpy.c, wcsmbs/mbsrchr.c, wcsmbs/mbstomb.c,
        wcsmbs/mbstr.h, wcsmbs/wcstr.h, wcsmbs/wcswcs.c: Removed.
        Implement functions from early drafts, not part of final standard.

Sun Mar 31 16:50:41 1996  Roland McGrath  <roland@whiz-bang.gnu.ai.mit.edu>

	* setjmp/setjmp.h (jmp_buf): Change gratuitous struct tag name to
	__jmp_bug_tag so its C++ implicit typedef does not conflict with the
	__jmp_buf typedef.

	* Makerules (BUILD_CFLAGS) [! objdir]: Use $(..)config.h when
	compiling in the source directories.

Fri Mar 29 16:26:35 1996  Roland McGrath  <roland@whiz-bang.gnu.ai.mit.edu>

	* sysdeps/libm-ieee754/w_gamma.c: Use signgam instead of __signgam.
	* sysdeps/libm-ieee754/s_signgam.c: Undo last change.
