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>

	* MakeTAGS: Clean up use of --omit-header and -n for xgettext.
	* po/header.pot: Add empty line at end.

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>

	* elf/dl-load.c (_dl_map_object): Save name in malloced memory.
	(_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
 	<marcus@sysc.pdx.edu> for the patch.)
