So, that now sounds like you want a full source-to-soruce translator.
If you want to do a very high-quality job, that can be very painful.  If
you want to merely do an okay job, that's pretty straight forward.

Check out the C/GCC translator that's available on antlr.org. In terms of
the rewriting, the idea is to start with a clean treeparser (like
GnuCTreeParser) and then, if you need to do any structural changes, create
one or more tree transformation passes.  In terms of printing out the tree,
check out GnuCEmitter.g for an example of one way of doing it.

Have fun,
