I didn't like that feature of the patch much either, but the signature
of the mutex_init function is specified in gthr.h:

     __GTHREAD_MUTEX_INIT_FUNCTION
            some systems can't initialize a mutex without a
        function call.  On such systems, define this to a
        function which looks like this:
          void __GTHREAD_MUTEX_INIT_FUNCTION (__gthread_mutex_t *)

The recursive one says it should have the same signature, and I (maybe
wrongly) assumed the cond_init one should too.
