Cool! This technique should work on all preprocessors. Yesterday I
wrote an implementation of the WHILE macro that does not require one to
explicitly pass the recursion depth as a parameter. (I don't have access
to the CVS at the moment.)

BTW: You don't need to use CONCAT()(X,Y) you can also just use
CONCAT(X,Y) simply by not making the macro a function style macro.
