from include/ext/concurrence.h:151-165 (trunk r187249):

  public:
    __mutex()
    {
#if __GTHREADS
      if (__gthread_active_p())
        {
#if defined __GTHREAD_MUTEX_INIT
          __gthread_mutex_t __tmp = __GTHREAD_MUTEX_INIT;
          _M_mutex = __tmp;
#else
          __GTHREAD_MUTEX_INIT_FUNCTION(&_M_mutex);
#endif  
        }
#endif
    }
