I don't know about RATS, but in general one reason to write your own
scanner is if you want to look at all the #if alternatives.  The
compiler only looks at one at a time.  This can be a problem since in
many cases you can't even compile the non-taken #if branches on a
given box.  So which approach you take must depend on the problem and
your goals.
