The cast was significant, but it's not needed anymore.
PTHREAD_MUTEX_INITIALIZER can be only used in initialization expression, not
regular assignment and that's why there was the cast. But now I'm assigning an
already-initialized mutex:
_LIBCPP_CONSTEXPR pthread_mutex_t __os_mutex_init = PTHREAD_MUTEX_INITIALIZER;
thus the cast is not needed anymore.
