I see. In 'libgfortran/io/async.c' there is

   ```
     async_unit *au = u->au;
     LOCK (&au->lock);
     thread_unit = u;
     au->thread = __gthread_self ();
   ```

so indeed `thread` should be `__gthread_t`. By the way I reported this issue four months ago and 
haven't received any response so far:
