While it isn't a good solution, it is a technique for getting going, you
could hack up the header file by hand to include just the statements you
think you want and see if that would allow you to do what you want to do.
If that fails, you have a lot more to worry about than a few compiler
warnings. If it does work, you can then do two things:
1. Continue developing the application you're working on
2. Fight the full-header-file battle
