* 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.
