Comment (by kencu):

 This would do it:
 {{{
 #if defined(RB_THREAD_T_HAS_NATIVE_ID) || defined(__APPLE__) &&
 (__ENVIRONMENT_MAC_OS_X_VERSION_MIN_REQUIRED__ > 1050)
 static VALUE
 native_thread_native_thread_id(rb_thread_t *target_th)
 {
 #ifdef RB_THREAD_T_HAS_NATIVE_ID
     int tid = target_th->tid;
     if (tid == 0) return Qnil;
     return INT2FIX(tid);
 #elif defined(__APPLE__)
     uint64_t tid;
     int e = pthread_threadid_np(target_th->thread_id, &tid);
     if (e != 0) rb_syserr_fail(e, "pthread_threadid_np");
     return ULL2NUM((unsigned long long)tid);
 #endif
 }
 # define USE_NATIVE_THREAD_NATIVE_THREAD_ID 1
 #else
 # define USE_NATIVE_THREAD_NATIVE_THREAD_ID 0
 #endif
 }}}
