A compiler that substitutes for parameters within either kind of
quote will violate the current working draft of the X3J11 committee
of ANSI.  The Reiser pre-processor (used in most UNIX systems) does
do this substitution.  It is safest not to write anything that would
be treated differently by these interpretations.
