Update.

2003-12-23  Jakub Jelinek  <jakub@redhat.com>

	* sysdeps/unix/sysv/linux/raise.c (raise): Protect pid = selftid
	setting with __ASSUME_TGKILL || defined __NR_tgkill.
	If pid is 0, set it to selftid.
	* sysdeps/unix/sysv/linux/getpid.c (really_getpid): Make inline.
	Don't set self->pid but self->tid.  If self->pid == 0 and self->tid
	!= 0, return self->tid without doing a syscall.
	* descr.h (struct pthread): Move pid field after tid.

	* Makefile (tests): Add tst-raise1.
	* tst-raise1.c: New file.
