Hey

I feel a little confused reading that, are you in your gcc front-end
doing #include <bla> which is c-code  generated from this 3rd tool
which generates the generic you want within your front-end? So
basically that means you need to re-compile your front-end every time
you want to compile a new file. I really dont understand why you would
do this approach to be honest. It means you basically have a
hard-coded input and output each time you compile your front-end.

Maybe i am missing something but i dont see why you would do this.
