The example made the question ambiguous.  If the intent was to process the
#ifdef directives *without* expanding all the #defines, then the problem is
more interesting.  Things to check: `unifdef', `cpp -S'; the comp.sources
archives; the Free Software Foundation.

Exercise: if none of the above work, design and implement such a tool and
release it as Freeware.
