Yes. I'd move EIEIO upstream in some 'fallback-libs' directory or
similar, and put this in load-path when Emacs version is <23.4 during
compilation as well as when CEDET is loaded.

Yes. Our minimum version currently is 23.2, and as long as it does not
become too painful, there's no need to bump it.

Actually, that feature will be part of the upcoming 24.4 release, so it
won't be needed there.

I don't think this should be too difficult, but if it turns out to be a
nightmare, I think we could bump the minimum version to 23.4 without
alienating too many people...
