Actually, I'm using g++'s -MM option to automatically generate the rules. The above technique is not support by gcc. And it seems not convenient to be handled by gcc. I'm wondering if gmake (or in general, make) can make some changes on the way these special characters are handled. So that I can use g++'s -MM options for arbitrary filename.
