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

vrregset_t.
2003-12-16 Steven Munroe <sjmunroe@us.ibm.com>
* sysdeps/unix/sysv/linux/powerpc/sys/procfs.h [!__PPC64_ELF_H]: Extent
conditional to include typedef elf_vrreg_t.
2002-12-17 Paolo Bonzini <bonzini@gnu.org>
* posix/regexec.c (re_search_internal): Limit search to the
beginning of the buffer if the initial states are empty for
contexts that do not include CONTEXT_BEGBUF or, if
!preg->newline_anchor, that do not include any one of
CONTEXT_BEGBUF and CONTEXT_NEWLINE.
2003-09-27 Wolfram Gloger <wg@malloc.de>
* malloc/malloc.c: Include <malloc-machine.h> earlier instead of

system-specific malloc-machine.h. Remove extra ; from extern "C"
closing brace.
* sysdeps/generic/malloc-machine.h: New file.
* sysdeps/mach/hurd/malloc-machine.h: New file.

variables only used if TLS_TCB_AT_TP is defined into the #if
branch.
