Hi!

When libgomp is compiled on target without sync builtins,
we weren't unlocking gomp_remaining_threads_lock at the end of
GOMP_parallel_end.  Fixed thusly, committed (so far) to the trunk.

2010-12-02  Jakub Jelinek  <jakub@redhat.com>

	PR libgomp/45240
	* parallel.c (GOMP_parallel_end): Unlock gomp_remaining_threads_lock
	at the end if sync builtins aren't supported.
