If we're going to go to this length, it seems more straightforward to
just check the .c/.h files into version control, like every other
project that I have such knowledge of.

To be fair, our grammar changes much more often. One other possible
deal-breaker of that is that it makes it more painful for forks to
maintain additional syntax.
