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.
