Ulrich Drepper 5aa8ff620e Update.
1998-04-21 18:00  Ulrich Drepper  <drepper@cygnus.com>

	* iconv/gconv.c (__gconv): Remove bogus input buffer size computation.

	* iconv/gconv_open.c (__gconv_open): Initialize outbufend element.

	* iconv/gconv_simple.c (__gconv_transform_internal_ascii): Don't use
	character in comparison with uint32_t.
	(__gconv_transform_internal_utf8): Specify MAX_NEEDED_TO.
	(__gconv_transform_utf8_internal): Specify MAX_NEEDED_FROM.
	Optimize BODY a bit.

	* iconv/loop.c: Require MIN_NEEDED_INPUT and MIN_NEEDED_OUTPUT to
	be defined.

	* iconv/skeleton.c: Also reset converted counter in case of an error.
	Call reset function using correct value for output buffer start.

	* iconvdata/Makefile: Re-enable tests.

	* iconvdata/iso8859-1.c: Swap MIN_NEEDED_INPUT and MIN_NEEDED_OUTPUT
	value for to-conversion.

	* iconvdata/TESTS: Add new third column.
	* iconvdata/run-iconv-test.sh: Add support for charsets which are
	not ASCII based.
	* iconvdata/testdata/suntzus: New file.

	* elf/dl-minimal.c (__strtol_internal): Increment pointer to string
	while reading.  Correctly used base.  Little optimization.
	(__strtoul_internal): Likewise.

	* elf/rtld.c (dl_main): Test to avoid duplicate call of _dl_init_paths
	was wrong.  Use explicit variable.

	* configure.in: Check for awk.
	* config.make.in: Add AWK to be substituted.

	* manual/xtract-typefun.awk: Rewrite to eliminate gawk extensions.
	* manual/users.texi: Fix typo exposed by above rewrite.

	* Makefile: Invoke awk using AWK variable.
	* csu/Makefile: Likewise.
	* elf/Makefile: Likewise.
	* mach/Makefile: Likewise.
	* manual/Makefile: Likewise.
	* sysdeps/gnu/Makefile: Likewise.
	* sysdeps/mach/hurd/Makefile: Likewise.
	* sysdeps/unix/Makefile: Likewise.
	* timezone/Makefile: Likewise.

1998-04-10  Gordon Matzigkeit  <gord@profitpress.com>

	* sysdeps/gnu/errlist.awk (ERR_REMAP): Implement error code to
	array index translation.
	(SYS_ERRLIST_ALIAS, SYS_NERR_ALIAS): Make weak aliases only if
	these are defined.

	* sysdeps/mach/hurd/Dist: Add errlist.c to distribution.

	* sysdeps/mach/hurd/errlist.c: New file.
	(ERR_TRANSLATE): Map Hurd error codes into errlist indices.
	(_hurd_errlist): The Hurd error list doesn't have Unix sys_errlist
	semantics, so rename it.

1998-04-16  Andreas Schwab  <schwab@issan.informatik.uni-dortmund.de>

	* iconvdata/run-iconv-test.sh: Make portable.  Always test all
	conversions.

1998-04-21 12:30  H.J. Lu  <hjl@gnu.org>

	* wcsmbs/wcsrtombs.c (__wcsrtombs): Initialize result to 0.
	* wcsmbs/wcsnrtombs.c: Likewise.
