Unfortunately, I couldn't install this: your definition of
cpp-font-lock-keywords in font-lock.el causes regex-opt to be loaded,
and that in turn triggers an error message from eval.c:do_autoload,
like this:

    Loading font-lock...
    Attempt to autoload regexp-opt-depth while preparing to dump

because regex-opt is not preloaded.  This breaks the build of Emacs,
since font-lock is now preloaded in loadup.el.

So I think you need to slightly change your code to defer the calls to
regex-opt to run time.
