does that mean using the PTHREAD_MUTEX_INITIALIZER as defined in
phread.h (which DirectFB does) does not work on parisc, and we _have_ to
call pthreas_mutex_init()? Why does PTHREAD_MUTEX_INITIALIZER exist
then?


#define PTHREAD_MUTEX_INITIALIZER \
  {0, 0, 0, PTHREAD_MUTEX_TIMED_NP, __LOCK_INITIALIZER}
