It really shouldn't matter, as long as all the inputs, outputs, and
clobbers are correct. If "volatile" does make a difference, we're
looking at a compiler bug.
I've looked hard at the register and clobber lists in MACC and MACC2
and AFAICS they're fine. Maybe someone else should look too.
One thing may be relevant: the asm in the "sub" function doesn't
clobber "cc". I think it should.
