A simple question for those of you who know.  Probably I should have posted
to a more general C board, but here it goes.

Does the C preprocessor ever do any calculations or does it only do search
and replace?  This question is very confusing and demands an example:

#define foo 5
#define bar 8
#define baz ((foo * bar) >> 1)

integer=baz;

Basically, what I want to know is this...
Can I make the C preprocessor (specifically Think C) actually calculate
the value for baz at compile time?
I would like to be able to use this syntax to define baz as 20 instead of 
((foo * bar) >> 1).

Thanks,
