    Oh, yes there is.

if (CONFIG_FOO) {
....
} else {
....
}

gcc can optimize that away and parser will see the whole thing.

I'm not sure I like this construct either.

Yes, it does mean gcc makes all the decisions and allows the
c-compiler to to more checking (as opposed to the preprocessor which
obviosly is really dumb) but it also assumes the compiler will always
elimiate dead code and I'm not convinced it's any more readable that
have "#if foo" scattered through the code.
