Update.
2004-12-16 Jakub Jelinek <jakub@redhat.com>
* sysdeps/unix/sysv/linux/sparc/sparc32/clone.S (__clone): Add support
for NPTL where the PID is stored at userlevel and needs to be reset
when CLONE_THREAD is not used.
* sysdeps/unix/sysv/linux/sparc/sparc64/sysdep.h
(SYSCALL_ERROR_HANDLER): If RTLD_PRIVATE_ERRNO, use rtld_errno
instead of errno.
* sysdeps/unix/sysv/linux/sparc/sparc64/socket.S: Include
sysdep-cancel.h instead of sysdep.h. Handle cancellation.
* sysdeps/sparc/sparc64/fpu/libm-test-ulps: Regenerate.
* sysdeps/ieee754/ldbl-128/e_expl.c: Include stdlib.h.
