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.
