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>

<streambuf.h>.
* sysdeps/unix/sysv/linux/_G_config.h: Likewise.

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):
