+	* Makefile (CFLAGS-ftrylockfile.c): Add -D_IO_MTSAFE_IO.
+
+	* cleanup.c: Move declarations of _GI_pthread_cleanup_push and
+	_GI_pthread_cleanup_pop to pthreadP.h.
+
+	* ftrylockfile.c: Use _IO_lock_trylock instead of
+	pthread_mutex_trylock.
+
+	* pthreadP.h (CANCEL_ASYNC): Use __pthread_setcanceltype.
+	(CANCEL_RESET): Likewise.
+	(__pthread_setcanceltype_): Declare.
+	(__pthread_mutex_lock_internal): Declare.
+	(__pthread_mutex_unlock_internal): Declare.
+	(__pthread_once_internal): Declare.
+	(pthread_cleanup_push): Redefine using _GI_pthread_cleanup_push.
+	(pthread_cleanup_pop): Redefine using _GI_pthread_cleanup_pop.
+
+	* pthread_cond_timedwait.c: Use INTUSE is calls to pthread_mutex_lock
+	and pthread_mutex_unlock.
+	* pthread_cond_wait.c: Likewise.
+	* pthread_mutex_lock.c: Use INTDEF to define alias if needed.
+	* pthread_mutex_unlock.c: Likewise.
+

+	open, write, and close respectively.
+
+	* sysdeps/pthread/bits/libc-lock.h (__libc_lock_trylock_internal):
+	Rewrite as statement expression since it must return a value.
