Mine.  But I can only guess a fix and not test it.  Basically we now absolutely
require the GTHREAD_ONCE stuff, please have a try providing it for darwin
(I can see a manual page for pthread_once at least).

I see in unwind-dw2-fde-darwin.c:

/* Carefully don't include gthr.h.  */

what's that about?  It looks like that hack no longer works with the
changed condition for using __GTHREAD_MUTEX_INIT_FUNCTION.
