   If you use a logical or (||) instead of bitwise (|), it
   seems to generate correct code.

That's a useful workaround, but it's still a bug...  MPW C has had problems
with the values of comparison expression ever since 3.0 (the switch from
Green Hills C to Apple C).  Sigh.  And no end in sight...

Grumble, grumble :).
