Thu Sep  5 03:20:42 1996  Ulrich Drepper  <drepper@cygnus.com>

	Change configuration and Makefiles to allow add-ons to have a
	sysdeps/ directory hierachy.
	* configure.in: Test for sysdeps/ directory in add-ons.  Before
	all test and searches in these hierachies, too.
	* Makeconfig (full-config-subdirs): Define based on $(config-sysdirs).
	Extend with $(..) if not absolute path.
	Use $(full-config-subdirs) where $(config-sysdirs) was used.
	* Makefile ($(objpfx)sysd-dirs): Use config-sysdirs.
	* MakeTAGS: Use $(full-config-subdirs).
	* Makerules: Change comment to libc.so link script.
	(sysdirs): Define based on $(full-config-subdirs).
	(sysd-Makefile): Define using config-sysdirs.
	(sysd-rules): Likewise.
	* sysdeps/unix/Makefile (sysd-syscalls): Define based on +sysdep-dirs.
	* sysdeps/unix/make-syscalls.sh: Remove basedir argument.

Wed Sep  4 01:32:21 1996  Andreas Schwab  <schwab@issan.informatik.uni-dortmund.de>

	* sysdeps/m68k/fpu/k_cos.c: Rewritten for better accuracy.
	* sysdeps/m68k/fpu/k_sin.c: Likewise.
	* sysdeps/m68k/fpu/k_tan.c: Likewise.

Thu Sep  5 01:06:09 1996  Richard Henderson  <rth@tamu.edu>

	* malloc/free.c (free): Protect by using __libc_malloc_lock.
	* malloc/malloc-find.c (malloc_find_object_address): Likewise.
	* malloc/malloc-size.c (malloc_usable_size): Likewise.
	* malloc/malloc-walk.c (malloc_walk): Likewise.
	* malloc/memalign.c (memalign): Likewise.
	* malloc/realloc.c (realloc): Likewise.
	* malloc/malloc.c: Define __libc_malloc_lock.
	(_malloc_internal): Don't use `malloc'.  Instead look for
	`__malloc_hook' or call `_malloc_internal'.
	(malloc): Protect by using `__libc_malloc_lock'.
	* malloc/malloc.h: Declare `__libc_malloc_lock'.

Mon Sep  2 22:42:59 1996  Richard Henderson  <rth@tamu.edu>

	* sysdeps/alpha/elf/start.S: Use weak_alias for __start
	instead of the hard definition.

	* sysdeps/alpha/dl-machine.h (RTLD_START): Add type info for
	_start and _dl_start_user.

	* sysdeps/unix/sysv/linux/alpha/init-first.h (SYSDEP_CALL_INIT):
	Make _dl_starting_up weak.  Add type info for NAME.

Mon Sep  2 22:15:14 1996  Richard Henderson  <rth@tamu.edu>

	* Makefile (all): Add extra_solibs pass.
	(+subdir_targets): Same.
	* Rules (extra_solibs): New phony empty target for subdirs without
	extra libs.
	* extra-lib.mk: Build lib*.so* in extra_solibs not lib-noranlib.
	* manual/Makefile: Add dummy extra_solibs target.

Sun Sep  1 15:41:22 1996  Richard Henderson  <rth@tamu.edu>

	* Makeconfig (+link): Add $(link-extra-libs).
	(link-extra-libs): New variable which expands to the full paths of
	the other libraries needed by a program, as controled by LDLIBS-$(@F).
	* db/Makefile: Use LDLIBS-makedb to link libdb not a dependency, as
	the later attempts to install the library before linking it.

	* sysdeps/unix/alpha/sysdep.S: Align errno.

	* sysdeps/unix/sysv/linux/alpha/ioperm.c (struct platform): Add
	hae_shift entry.
	(io): Move bus_memory_base and sparse_bus_memory_base into struct.
	(_hae_shift): New function.
	* sysdeps/unix/sysv/linux/alpha/sys/io.h: New file.  Prototypes
	for the bus query functions.

Sat Aug 31 18:14:54 1996  Richard Henderson  <rth@tamu.edu>

	* elf/dl-close.c (_dl_close): In static executables, map->l_prev
	can be NULL when unloading a library.

	* elf/dl-open.c (_dl_open): Pass __environ instead of __libc_envp
	to the library .init function.

	* sysdeps/alpha/dl-machine.h (elf_machine_rela):  Since we omitted
	part of the COPY reloc processing earlier, omit the rest now --
	we'll get into less trouble later when some fool does use a COPY.

	* sysdeps/unix/sysv/linux/init-first.c (init): Accept argc et al as
	parameters.  Move all argc and __libc_multiple_libcs calculation out
	to init-first.h.  Use __environ not __libc_envp.
	* sysdeps/unix/sysv/linux/alpha/init-first.h: Rewrite.
	* sysdeps/unix/sysv/linux/i386/init-first.h: Rewrite.

Thu Aug 29 20:26:40 1996  Andreas Schwab  <schwab@issan.informatik.uni-dortmund.de>

	* sysdeps/posix/profil.c (profil): Don't clobber saved timer and
	signal settings when profiling was already turned on.

	* csu/gmon-start.c (__gmon_start__) [HAVE_INITFINI]: Protect from
	being called twice.

Wed Sep  4 01:31:50 1996  Ulrich Drepper  <drepper@cygnus.com>

	* sysdeps/unix/sysv/linux/i386/mmap.S: Test for
	0 < return value < -4096 and not < 0 to decide about failure.
	Reported by Andreas Jaeger.

Tue Sep  3 19:04:05 1996  Ulrich Drepper  <drepper@cygnus.com>

	* stdio-common/vfscanf.c (__vfscanf): Don't count EOF char
	in %c format.

Sat Aug 31 18:10:51 1996  Ulrich Drepper  <drepper@cygnus.com>

	* wcsmbs/wchar.h: Define prototypes for wcstoq and wcstouq only
	#ifdef __USE_GNU.

Sat Aug 31 12:34:29 1996  Ulrich Drepper  <drepper@cygnus.com>

	* version.c: Add missing newline character in banner.

	* sysdeps/unix/sysv/linux/alpha/Dist: Correct typo.
	* sysdeps/unix/sysv/linux/i386/Dist: Likewise.

Sat Aug 31 03:07:39 1996  Ulrich Drepper  <drepper@cygnus.com>

	* intl/l10nflist.c (_nl_normalize_codeset): We convert to lower
 	case, so don't prepend uppercase `ISO' for only numeric arg.
