Update.

1998-02-13 17:39  Ulrich Drepper  <drepper@cygnus.com>

	* elf/Makefile: Don't use --version-script parameter to link ld.so
	unconditionally.

1998-01-02 04:19  Geoff Keating  <geoffk@ozemail.com.au>

	* math/Makefile: Add t_exp.
	* math/libm-test.c: Tighten accuracy bounds for exp(), correct
	constants.
	* math/test-reduce.c: Remove temporarily, it seems to be broken.
	* sysdeps/libm-ieee754/e_exp.c: Use accurate table method.
	* sysdeps/libm-ieee754/e_expf.c: Use table & double precision for
	better accuracy.
	* sysdeps/libm-ieee754/s_exp2.c: Use better polynomial; correct
	algorithm for very large/very small arguments.
	* sysdeps/libm-ieee754/s_exp2f.c: Use slightly better polynomial;
	correct algorithm for very large/very small arguments; adjust for
	new table.
	* sysdeps/libm-ieee754/t_exp.c: New file.
	* sysdeps/libm-ieee754/t_exp2f.h: Use table with smaller deltas.

	* sysdeps/unix/sysv/linux/powerpc/dl-sysdep.c: Put 'strange test'
	back, with comment that explains what breaks when you remove it :-(.

	* localedata/xfrm-test.c: Avoid integer overflow.

	* stdlib/strfmon.c: char is unsigned, sometimes.

	*sysdeps/powerpc
	* sysdeps/powerpc/Makefile: Remove quad float support.
	* sysdeps/powerpc/q_*.c: Remove, they will become an add-on.
	* sysdeps/powerpc/quad_float.h: Likewise.
	* sysdeps/powerpc/test-arith.c: Likewise.
	* sysdeps/powerpc/test-arithf.c: Likewise.

	* sysdeps/generic/s_exp2.c: Remove, we have this implemented now.
	* sysdeps/generic/s_exp2f.c: Likewise.

	* sysdeps/powerpc/bits/mathinline.h: Use underscores around __asm__,
	don't try anything if _SOFT_FLOAT.

1997-12-31  Andreas Schwab  <schwab@issan.informatik.uni-dortmund.de>

	* locale/C-ctype.c (_nl_C_LC_CTYPE_class32): Undo last change.
	* locale/programs/ld-ctype.c (CHAR_CLASS32_TRANS): Likewise.
	* wctype/wctype.c: Likewise.
	* wctype/wctype.h (_ISwxxx): Renamed from _ISxxx, all uses
	changed.  They are incompatible with the _ISxxx values from
	<ctype.h> on little endian machines.
	(_ISwbit) [__BYTE_ORDER == __LITTLE_ENDIAN]: Correctly transform
	bit number.  This fixes the real bug and restores the integrity of
	the ctype locale file.
	* wctype/wcfuncs.c: Change all _ISxxx to _ISwxxx.
	* wctype/wcfuncs_l.c: Likewise.
	* wctype/wcextra.c: Likewise.
	* wctype/wctype_l.c [__BYTE_ORDER == __LITTLE_ENDIAN]: Use correct
	byte swapping.

1998-02-09  Andreas Schwab  <schwab@issan.informatik.uni-dortmund.de>

	* sysdeps/unix/sysv/linux/sparc/sparc32/sysdep.S (errno): Put it
	into .bss segment instead of .common, so that aliases on it work.

	* sysdeps/unix/sysv/linux/i386/sysdep.S (errno): Add .type and
	.size directives, put into .bss segment instead of initializing it
	to 4.

1998-02-12 08:00  H.J. Lu  <hjl@gnu.org>

	* libc.map (gnu_get_libc_release, gnu_get_libc_version): Added.

	* version.c (__gnu_get_libc_release, __gnu_get_libc_version): New
	functions.
	Make names without __ weak aliases.
	(__libc_release, __libc_version): Make them static.

	* include/gnu/libc-version.h: New file.
	* Makefile (headers): Add gnu/libc-version.h.

1998-02-13  Ulrich Drepper  <drepper@cygnus.com>

	* stdlib/stdlib.h (struct drand48_data): Leave X to user macros
	and use x for member name.
	Reported by Daniel Lyddy <daniell@cs.berkeley.edu>.

	* stdlib/drand48.c: Change according to member name change.
	* stdlib/drand48_r.c: Likewise.
	* stdlib/lcong48_r.c: Likewise.
	* stdlib/lrand48.c: Likewise.
	* stdlib/lrand48_r.c: Likewise.
	* stdlib/mrand48.c: Likewise.
	* stdlib/mrand48_r.c: Likewise.
	* stdlib/seed48.c: Likewise.
	* stdlib/seed48_r.c: Likewise.
	* stdlib/srand48_r.c: Likewise.

1998-02-11  Andreas Jaeger  <aj@arthur.rhein-neckar.de>

	* nss/test-netdb.c: Add some more test cases.

1998-02-13 11:39  Ulrich Drepper  <drepper@cygnus.com>

	* libio/iovsscanf.c: Undo last change modifying errno.

1998-02-12  Andreas Schwab  <schwab@issan.informatik.uni-dortmund.de>

	* stdio-common/vfscanf.c: Never try to read another character
	after EOF.  Don't decrement read_in after EOF, it wasn't
	incremented in the first place.
	(NEXT_WIDE_CHAR): Set First, not first.

1998-02-06 07:48  H.J. Lu  <hjl@gnu.org>

	* db/Makefile ($(inst_libdir)/libndbm.a,
	$(inst_libdir)/libndbm.so): New targets.
	* db2/Makefile: Likewise.

1998-02-12 08:20  H.J. Lu  <hjl@gnu.org>

	* sysdeps/gnu/errlist.awk (sys_errlist, sys_nerr): Create weak
	aliases if HAVE_ELF or PIC or DO_VERSIONING is not defined.

1998-02-12  Andreas Schwab  <schwab@issan.informatik.uni-dortmund.de>

	* sysdeps/generic/_G_config.h: Define _G_wchar_t, for C++
	<streambuf.h>.
	* sysdeps/unix/sysv/linux/_G_config.h: Likewise.

1998-02-11  Andreas Schwab  <schwab@issan.informatik.uni-dortmund.de>

	* sysdeps/unix/make-syscalls.sh: Fix sed pattern when dealing with
	versioned symbols.

1998-02-13 08:14  H.J. Lu  <hjl@gnu.org>

	* libc.map (_dl_global_scope, _dl_lookup_symbol_skip,
	_dl_lookup_versioned_symbol, _dl_lookup_versioned_symbol_skip):
	Added for libdl.so.







	* elf/rtld.map: New file.  Needed to define the GLIBC_2.*

	* manual/socket.texi (Host Address Functions): Clarify description
	* sysdeps/unix/sysv/linux/alpha/bits/time.h (struct timeval):
