2008-05-05  Benjamin Kosnik  <bkoz@redhat.com>

        * gthr-single.h: Add in required interface elements as per gthr.h.
        Add stub types for __gthread_key_t, __gthread_once_t. Add defines
        for __GTHREAD_ONCE_INIT, __GTHREAD_RECURSIVE_MUTEX_INIT.
        Generalize UNUSED macro.
        (__gthread_once): Add.
        (__gthread_key_create): Add.
        (__gthread_key_delete): Add.
        (__gthread_getspecific): Add.
        (__gthread_setspecific): Add.
