Sure, but there are a few dependencies that seem important enough to
hard-wire into the Makefiles, so that they'll be honored even if you
don't do --enable-depend. backend/parser has some, for example.
This one seemed to me to be of that ilk. I expect to have to be careful
if I hack .h files without having enabled dependencies ... but one
normally doesn't need to think about that for .c files.
