Update.

2004-11-12  Ulrich Drepper  <drepper@redhat.com>

	* sysdeps/unix/sysv/linux/libc_fatal.c: Add new function __libc_message
	which performs the printing and simple format string handling.  The
	string is written to tty, stderr, syslog in this order, stopping after
	the first successful output.
	(__libc_fatal): Call __libc_message.
	* include/stdio.h: Declare __libc_message.
	* malloc/malloc.c (malloc_printerr): Use __libc_message.
	* debug/chk_fail.c: Also print message with __libc_message.
	* debug/test-strcpy_chk.c: Ensure that debug messages are not printed
	to the terminal or stderr.
	* debug/tst-chk1.c: Likewise.

	* posix/Makefile: Remove gpl2lgpl variable.
