+ * pthread_getsequence_np.c: New non-POSIX interface for compatibility
+ with some other implementations; returns a 64 bit sequence number
+ that is unique to each thread in the process.
+ * pthread.h (pthread_getsequence_np): Added.
+ * global.c: Add global sequence counter for above.
+ * implement.h: Likewise.

* (cancelLock): Convert to an MCS lock and rename to stateLock.
