+ * sysdeps/unix/sysv/linux/sh/bits/pthreadtypes.h (pthread_cond_t):
+ Add __broadcast_seq field.
+ * sysdeps/unix/sysv/linux/sh/pthread_cond_broadcast.S: Mark
+ all waiters as woken with woken_seq and bump broadcast counter.
+ * sysdeps/unix/sysv/linux/sh/pthread_cond_wait.S: Use new
+ __broadcast_seq. Increment __woken_seq correctly when cleanuped.
+ * sysdeps/unix/sysv/linux/sh/pthread_cond_timedwait.S: Likewise.
+ Comment typo fixes. Avoid returning -ETIMEDOUT.
