While I believe it is quite substantial work, you may want to look
into it anyways :-) Note that I don't think 'include etc.' can work
in general. You may be able to reintroduce the includes, but definitely
not the macros.

Here is how 'ctool' / 'synopsis' do it:

* the parser receives preprocessed code

* the parser generates special parse tree nodes as markers where
   the header is entered and where it is left (use '#line' directives
   to figure out the exact place).

* you need a way to find out what the header name was that was
   originally used, and whether it used <> or "" (synopsis has some
   special logic to interact with the preprocessor to get at that data)

* finally, when regenerating the code, you through out everything
   in between the markers and replace it by the stored include
   directive
