Fri Jul 26 04:41:28 1996 Ulrich Drepper <drepper@cygnus.com>

Browse Source 
* intl/libintl.h: Define optimizing macros if __OPTIMIZE__ is
	defined, not __OPTIMIZED.
	(_nl_msg_cat_cntr): Move declaration outside macro definition
	to prevent "nested extern" warning.
	(dcgettext): Rename local variable `result' to `__result'.

Thu Jul 25 22:46:30 1996  Roland McGrath  <roland@delasyd.gnu.ai.mit.edu>

	* locale/programs/localedef.c (__progname): Remove decl.
	(main): Use program_invocation_short_name instead of __progname.
	(usage): Use program_invocation_name instead of __progname.

Fri Jul 26 03:46:08 1996  Ulrich Drepper  <drepper@cygnus.com>

	* catgets/gencat.c: Use "libc" instead of PACKAGE.
	* locale/localedef.c: Ditto.
	* locale/locale.c: Ditto.

	* locale/findlocale.c (_nl_find_locale): Little optimization.
	Use new function `strndup'.

	* locale/loadlocale.c: Little optimization.  Use constant value
	from `_nl_category_num_items' instead of byte-order dependend
	value from file.

	* locale/programs/ld-time.c (time_add): Correct string constant.

	* locale/programs/locale-spec.c: New file.
	* locale/programs/locale.c: Call `locale_special' function if
	no other field matches.

	* locale/programs/localedef.c: No need to define `program_name'.
	Use global variable `__progname'.

	* locale/programs/locfile.c (write_locale_data): Always write
	LC_MESSAGES data in LC_MESSAGES/SYS_LC_MESSAGES file.  This is
	necessary since message catalogs are also installed in the
	LC_MESSAGES/ directory.

	* locale/programs/stringtrans.c (ADDC): Correctly use `encode_char'
	function instead of writing single bytes.
	(encode_char): Also handle little endian.

	* locale/setlocale.c (new_composite_name): Little optimization.
	Use return value of `memcpy'.

	* misc/ttyent.h: Pretty print prototypes, add missing parameter
	names, prepend parameter names with __  and use `__const' instead
	of `const'.
	* posix/unistd.h: Ditto.
	* stdlib/stdlib.h: Ditto.
	* string/string.h: Ditto.

	* posix/getconf.c: De-ASNI-fy.  Recognize POSIX.2 constant names.
	Use `error' function instead of doing it by hand.
	* sysdeps/posix/sysconf.c: De-ANSI-fy.
	Handle _SC_COLL_WEIGHTS_MAX.
	* sysdeps/stub/sysconf.c: Handle _SC_CHARCLASS_NAME_MAX,
	_SC_COLL_WEIGHTS_MAX, _SC_EQUIV_CLASS_MAX, _SC_2_LOCALEDEF
	since these do depend on the platform.
	Add POSIX.4 symbols.

	* posix/posix2_lim.h: Add missing definition of
	_POSIX2_COLL_WEIGHTS_MAX.
	Change _POSIX2_EQUIV_CLASS_MAX and _POSIX2_CHARCLASS_NAME_MAX
	to high values since we have no fixed limit.

	* sysdeps/generic/confname.h: Add _SC_PAGE_SIZE as alias for
	_SC_PAGESIZE for buggy systems (= HP UX) out there.

	* wcsmbs/Makefile (routines): Add mbsnrtowcs and wcsnrtombs.
	* wcsmbs/mbsnrtowcs.c: New file.  Non-standard implementation.
	* wcsmbs/wcsnrtombs.c: Ditto.
	* wcsmbs/wchar.h [__USE_GNU]: Add prototypes for mbsnrtowcs and
	wcsnrtombs.

Thu Jul 25 00:25:54  Richard Henderson  <rth@tamu.edu>

	* nss/nss_db/db-XXX.c: Kill trailing ; from lock defn as a matter of
	course.
	* nss/getXXent_r.c: Likewise.
	* nss/nsswitch.c: Likewise.
	* nss/nss_files/files-XXX.c: Likewise.
