  New Revision: 58804

  https://svn.ruby-lang.org/cgi-bin/viewvc.cgi?view=revision&revision=58804

  Log:
    thread_sync.c: rename mutex_waiter struct to sync_waiter
    
    We will reuse this struct for ConditionVariable, Queue, and SizedQueue,
    so it is no longer Mutex-specific.

  Modified files:
    trunk/thread_sync.c
