Update. 

2002-01-23  Richard Henderson  <rth@redhat.com>

	* 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.

2001-01-22  Paul Eggert  <eggert@twinsun.com>

	* 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.
