Just FYI, I had a similar problem generating an FFI interface to X11. 
There is a very nice C parser written in Ocaml called Cil. Attached is 
my parser using the Cil library. Its tailored to X11 in some ways but 
maybe you can get the gist of it. If you are interested in using it and 
don't know how to setup Cil I can explain how it goes.
