I suggested that. I don't know where to send that suggestion though.

I don't recall the details, but when I wrote the code originally that way it gave me errors. It's why I had the "Also called r12" comment next to the symbol declaration.
I agree, I'd rather have either one of those than this #ifdef workaround. I was supplying this as a potentially quicker fix for the problem Behan was hitting.
