It's not difficult to add a feature in ly2dvi to first run the
input files through a preprocessor like m4 or cpp, if there's
a public demand for it. Adding another macro language within
Lilypond, on the other hand, sounds like a silly idea. 
In input/les-nereides.ly, you can find an example on how to 
use cpp as a preprocessor.
