  Modified:    locks/unix thread_mutex.c
  Log:
  POSIX says that passing a mutexattr object with default attributes to
  pthread_mutex_init() is equivalent to passing NULL: simplify
  apr_thread_mutex_create() to do the latter.
  
  Fixes build on BSD/OS 4.0, which prototypes but does not implement
  pthread_mutexattr_{init,destroy}, fooling the autoconf checks.
