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.
