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.
