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.
