Update.
1998-11-30  Andreas Jaeger  <aj@arthur.rhein-neckar.de>

	* nscd/nscd_getpw_r.c: Include nscd_proto.h for prototypes.

	* sysdeps/generic/errno-loc.c: Include <errno.h> for prototype,
	undefine errno to get variable.

	* sysdeps/unix/sysv/linux/i386/setfsuid.c: Include <sys/fsuid.h>
	instead of <unistd.h> for prototype.
	* sysdeps/unix/sysv/linux/i386/setfsgid.c: Likewise.

1998-11-30  Ulrich Drepper  <drepper@cygnus.com>

	* misc/err.h: Correct comments and use protected attribute keywords.
	Reported by Joseph Myers <jsm28@cam.ac.uk>.

1998-11-29  Roland McGrath  <roland@baalperazim.frob.com>

	* malloc/thread-m.h [_LIBC]: Include <bits/libc-tsd.h>, and
	remove tsd stuff from pthreads/cthreads libc sections.
	Use __libc_tsd_define for MALLOC key.
	[_LIBC] (tsd_key_t, tsd_key_create): Define to a zero-size type and a
	no-op, respectively.
	[_LIBC] (tsd_setspecific, tsd_getspecific): Use __libc_tsd_get/set.

	* elf/dl-error.c: Include <bits/libc-tsd.h>.
	Use __libc_tsd_define for DL_ERROR key.
	(tsd_setspecific, tsd_getspecific): Rewritten using __libc_tsd_get/set.

	* sysdeps/mach/hurd/bits/libc-tsd.h: New file.
	* sysdeps/generic/bits/libc-tsd.h: New file.
	* Makefile (distribute): Add bits/libc-tsd.h.

1998-10-12  Roland McGrath  <roland@baalperazim.frob.com>

	* elf/dl-error.c: Remove kludge to check for ld.so load address.
	There is no need if weak undefined symbols are not used in ld.so;
	see linuxthreads/ChangeLog for changes to files
	linuxthreads/sysdeps/pthread/bits/libc-lock.h and
	linuxthreads/sysdeps/pthread/bits/libc-tsd.h.

1998-11-30  Andreas Jaeger  <aj@arthur.rhein-neckar.de>

	* sysdeps/i386/bits/string.h (__memset_cc): Fix typo (s->__s).

	* sysdeps/i386/i486/bits/string.h: Add prototypes for all new
	inline functions.
	* sysdeps/i386/bits/string.h: Likewise.

1998-11-30  Andreas Jaeger  <aj@arthur.rhein-neckar.de>

	* sysdeps/unix/sysv/linux/alpha/bits/ipc.h: Remove ipc_kludge.

1998-11-30  Andreas Schwab  <schwab@issan.cs.uni-dortmund.de>

	* db2/progs/db_load/db_load.c (main): Avoid -Wparentheses warning.
