Am I missing something or does this patch just change

  if (0) {
    return NULL;
  }

/* something */;
return to;

into

  if (0) {
    /* something */
    return to;
  }
  return NULL;

This shouldn't really make a difference. How old is your GCC?

Cheers,
Ahmad

The logic doesn't change with or without a patch, but yes, we can drop it.
