I don't think what you describe is possible in make alone. You will have to generate make-files with your header dependencies with GCC -MMd option, you will later have to include these files from your main make file. As you say, its possible but it feels like you are building hacks upon hacks. Add to that diamond shaped dependencies such as several h files including another generated h file and you're in for many sleepless nights.
