Both. But your fix is better than mine, so no worries.

Anyway, what I was doing to move Vlibrary_cache out of w32 is affected
by your patch, so I'd be happy if you could also fix that. The main
issue is making sure that dynamic loading can be used before dumping,
but the dumped Vlibrary_cache and image_types do not get dumped with
entries that would not be relevant afterwards (that's could be an
issue on Windows).
