The trick is simple enough to be re-discovered many times, cute
enough to be worth posting when discovered.  I see no reason
to assume the author knew of the previous posting.  Note the
slightly divergent treatment of the 0 case.  The Duff posting
was 20 months ago, which is a long time, in net terms.

There's nothing the matter with machine dependent code IF YOU
EXPLAIN IT AND MARK IT SO.  There is no such thing as a program
that runs too fast...
