Update.

* sysdeps/alpha/Makefile (pic-ccflag): New variable.
2002-01-28 Ulrich Drepper <drepper@redhat.com>
* string/strxfrm.c: Allocate one more byte for rulearr and clear
this element [PR libc/2855].
* string/strcoll.c: Handle zero-length arguments specially
[PR libc/2856].
2002-01-23 Jakub Jelinek <jakub@redhat.com>
* string/bits/string2.h (__mempcpy): For gcc 3.0+, don't use
__mempcpy_small but instead use __builtin_memcpy ( , , n) + n for
short lengths and constant src.
(strcpy): Don't optimize for gcc 3.0+.
(__stpcpy): For gcc 3.0+, don't use
__stpcpy_small but instead use __builtin_strcpy (, src) + strlen (src)
for short string literal src.
2002-01-23 Jeroen Dobbelaere <jeroen.dobbelaere@acunia.com>
* sysdeps/unix/sysv/linux/configure.in (libc_cv_gcc_unwind_find_fde):
Set for arm, too.

* manual/llio.texi (Linked Channels, Cleaning Streams):
Make it clearer that a just-opened input stream might need cleaning.
2002-01-21 H.J. Lu <hjl@gnu.org>
* sysdeps/mips/dl-machine.h (ELF_MACHINE_BEFORE_RTLD_RELOC):
Don't use label at end of compound statement.
