You might be interested in some work done by Thomas Foerster. Thomas has done a fairly detailed analysis of the current interdependencies in FlightGear's include files. IIRC, Thomas has a patched version of FlightGear that already removes most of the interdependencies. These updates are not publicly available yet. I had agreed to review his changes and commit them, as part of one of my current FlightGear priorities, but hadn't gotten around to do so yet.
