Is it coincidence that your post appeared in the newsgroup on April 1st

I think one possible path for you is to use ANTLR, which is written in
Java and thus usable with Jython. There are ANTLR grammar files for C,
C++, and a host of other languages. Also ANTLR is very sophisticated in
terms of the representations that it builds, e.g. AST's, etc, and in
terms of the ways in which you can manipulate these representations, for
optimisation, etc.
