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.
