A single extra symbol (for the unusual -O0 compilation) is better than 200 
before the patch though. I think the patch is a good thing (also for 
future-proofing) even if one or two extra symbols remain because they are 
hard to remove. Also, none of this is urgent, it can all wait several 
weeks if you are busy.
