These are of course the wrong way round.  The examples should be:

  r = some_system_call ();
  err = errno;
  do_cleanup ();
  errno = err;
  if (r == -1) {
    reply_with_perror ("failed");
    return -1;
  }

[can in future be changed to]

  r = some_system_call ();
  err = errno;
  do_cleanup ();
  if (r == -1) {
    reply_with_perror_errno (err, "failed");
    return -1;
  }
