	* locale/loadlocale.c (_nl_load_locale) [MAP_FILE]: Define it zero
 	if undefined.

	* string/strxfrm.c: Just copy the string (for now).
	* string/strcoll.c: Just call strcmp (for now).

	* mach/Makefile (lock): Add mutex-init.
	* mach/mutex-solid.c (_cthread_mutex_lock_routine,
 	_cthread_mutex_unlock_routine): Variables removed.
	(__mutex_lock_solid, __mutex_unlock_solid): Don't use them; just stub.
	(__mutex_init): Function moved to new file mutex-init.c.
	* mach/mutex-init.c: New file, broken out of mutex-solid.c.
