+	* allocatestack.c (allocate_stack): Always initialize robust_head.
+	* descr.h: Define struct robust_list_head.
+	(struct pthread): Use robust_list_head in robust mutex list definition.
+	Adjust ENQUEUE_MUTEX and DEQUEUE_MUTEX.
+	* init.c [!__ASSUME_SET_ROBUST_LIST] (__set_robust_list_avail): Define.
+	(__pthread_initialize_minimal_internal): Register robust_list with

+	* pthreadP.h: Remove PRIVATE_ from PTHREAD_MUTEX_ROBUST_* names.
+	Declare __set_robust_list_avail.

+	[!__ASSUME_SET_ROBUST_LIST]: If robust_list is not empty wake up

+	* pthread_mutex_destroy.c: For robust mutexes don't look at the
+	number of users, it's unreliable.
+	* pthread_mutex_init.c: Allow use of pshared robust mutexes if
