Yeah, I know it's "default", but it's not how our make files ever
treated these files before. At the risk of repeating myself: a change
of this sort was not discussed nor agreed to. And I'm not agreeing to
it. I don't care for the idea that the build tree after a regular make
might not include all files that would be in a distribution tarball.
A concrete usage case that this breaks is doing something likefind . -name '*.c' | xargs grep whatever
Up to now I've always been able to assume that that would catch
occurrences of "whatever" coming from *.y and *.l files. No more
though. Maybe the derived *.c files are there, or maybe they're
not --- it'll be really history-dependent.
Please just make them precious.
