----------
Of course, on some machines halfword arithmetic is slower than fullword
arithmetic and on others the opposite is true, so if speed is a major
consideration you may need to tailor your declaration to the specific
machine you're working on.  Maybe "int" should by convention be
the whatever style integer is the fastest to work with...
