In fact the cast this construction is still required, since the pthread_join
returned value might have a different size of the expected c11 thrd_join.

As a slight optimization I changed to 

  int err_code = __pthread_timedjoin_ex (thr, &pthread_res, NULL, true);

(it should avoid calling pthread_join which will in turn call
pthread_timedjoin_ex).
