	* sysdeps/unix/sysv/linux/i386/pthread_once.S (__pthread_once):
	Use correct cleanup handler registration.  Add unwind info.
	* tst-once3.c: Add cleanup handler and check it is called.
	* tst-once4.c: Likewise.
	* tst-oncex3.c: New file.
	* tst-oncex4.c: New file.
	* Makefile: Add rules to build and run tst-oncex3 and tst-oncex4.
