Update.
Wed Aug 14 21:36:16 1996 Ulrich Drepper <drepper@cygnus.com>
* stdlib/strtod.c (STRTOD): Correct assertion about size of
wint_t and wchar_t. Reported by David Mosberger-Tang.
Mon Aug 12 22:40:16 1996 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de>
* elf/dl-lookup.c (_dl_lookup_symbol): Remove fifth parameter
RELOC_ADDR and make NOPLT a set of flags. All callers
changed. Delete condition that checks for resolving to the
location being filled in. Add condition to skip the
executable's symbols if requested.
* elf/link.h: Change declaration of _dl_lookup_symbol
accordingly.
(DL_LOOKUP_NOEXEC, DL_LOOKUP_NOPLT): New definitions.
* elf/dl-reloc.c (RESOLVE): Remove second parameter and rename
NOPLT to FLAGS.
* elf/dl-runtime.c (RESOLVE): Likewise.
* elf/rtld.c (RESOLVE): Likewise.
* sysdeps/m68k/dl-machine.h (elf_machine_rela): Pass
DL_LOOKUP_NOEXEC as second argument to the RESOLVE macro if
processing a copy reloc, DL_LOOKUP_NOPLT for a jump slot
reloc, zero otherwise.
* sysdeps/alpha/dl-machine.h (elf_machine_rela): Likewise.
* sysdeps/i386/dl-machine.h (elf_machine_rel): Likewise.
* sysdeps/mips/dl-machine.h (elf_machine_rel): Likewise.
Wed Aug 14 17:57:08 1996 Ulrich Drepper <drepper@cygnus.com>

Sun Aug 11 13:45:33 1996 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de>
* MakeTAGS (all-pot): Remove $P/errlist.pot, all error messages
are now in $P/stdio-common.pot.
(XGETTEXTFLAGS-errlist.pot): Variable removed.
Mon Aug 12 19:25:03 1996 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de>
* Makerules (do-ar, o-iterator-doit): Compute path to autolock
script at run time, not configure time.
* config.make.in, configure.in: Undo previous change.
Wed Aug 14 13:20:02 1996 Ulrich Drepper <drepper@cygnus.com>
* sysdeps/unix/sysv/linux/i386/close.S: Push return value of thread
on stack as argument for `_exit'. Reported by Andreas Schwab.
Mon Aug 12 19:36:25 1996 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de>
* sysdeps/unix/sysv/linux/m68k/clone.S: New file.
Wed Aug 14 04:22:35 1996 Richard Henderson <rth@tamu.edu>

(_dl_map_object_from_fd): Free name on error.
Wed Aug 14 13:00:09 1996 Ulrich Drepper <drepper@cygnus.com>
* string/strdup.c: Use result of memcpy to avoid reloading.
Tue Aug 13 00:55:03 1996 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de>
* shadow/sgetspent_r.c (__sgetspent_r): Copy string to buffer, not
the other way round.
* resolv/Makefile (libresolv-routines): Add base64, inet_net_ntop,
inet_net_pton, inet_net.
* resolv/arpa/nameser.h (__BIND): Update version number.
Mon Aug 12 19:03:22 1996 Thomas Bushnell n/BSG <thomas@psilocin.gnu.ai.mit.edu>
* sysdeps/generic/gnu/types.h: Declare __fd_mask as `unsigned long'.
* mach/Makefile (mach/mach_host.uh): Depend on
$(objpfx)/mach-syscalls.mk.
($(objpfx)mach-shortcuts.h): Depend on $(objpfx)mach/mach_host.h.
(This fixes a make loop; thanks to Marcus Daniels
