This message triggered me to try to teach ccache how to cache preproc.y -> preproc.{c,h}, and I got that basically working[1], but upstream doesn't want it (yet). I'll try again if the proposed refactoring to allow more kinds of compiler-like-things goes somewhere. I think that started with people's struggles with GCC vs MSVC. Given the simplicity of this case, though, I suppose we could have a little not-very-general shell/python/whatever wrapper script -- just compute a checksum of the input and keep the output files around.
