I would introduce a macro expansion trough a compiler directive. Then
there is no need to scan the whole program for macro occurrencies. You
"only" have to preprocess the including directive and the macro body.

Doing {$I %macro(p1,p2,..)} instead of simple macro(p1,p2,..) helps
much.

It is a clean way, and pascal like. (in my eyes)
