Update.

2001-02-23  Andreas Jaeger  <aj@suse.de>

	* string/tester.c (test_strtok_r): Add testcase.
	(test_strtok_r): Always initialize cp for proper checking.

	* sysdeps/generic/strtok.c (strtok): Handle case of first strtok
	returning NULL correctly.
	Patch by Fumitoshi UKAI <ukai@debian.or.jp>.
	* sysdeps/generic/strtok_r.c (__strtok_r): Likewise.

2001-02-23  Ulrich Drepper  <drepper@redhat.com>

	* sysdeps/unix/sysv/aix/bits/types.h: Define __need_NULL before
	including <stddef.h>.
	* sysdeps/unix/sysv/aix/write.c: Define alias __libc_write.
	* include/libc-symbols.h (weak_alias): Don't use .weak if
	HAVE_ASM_GLOBAL_DOT_NAME is defined.
	Patches by Michael Keezer <mkeezer@redhat.com>.

	* sysdeps/generic/ftime.c: Don't include <sys/time.h> at all.
	Patch by Michael Keezer <mkeezer@redhat.com>.

	* sysdeps/unix/sysv/aix/Dist: Remove restf.S and savef.S.
	* sysdeps/unix/sysv/aix/Makefile [$(subdir) == misc]
	(sysdep_routines): Remove restf.S and savef.S.
	* sysdeps/unix/sysv/aix/restf.S. Removed.
	* sysdeps/unix/sysv/aix/savef.S. Removed.
	* sysdeps/powerpc/fprrest.S: Use C_TEXT to define label.  Also define
	alternative names used on some platforms.
	* sysdeps/powerpc/fprsave.S: Likewise.
	* sysdeps/powerpc/gprrest0.S: Likewise.
	* sysdeps/powerpc/gprrest1.S: Likewise.
