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.
