I think there's a simple heuristic: When make Klasses fails ;) Ofcourse,
this assumes it's ensured the "bootstrap" Klasses.jar isn't used for
anything else than that build. I think the C lib changes shouldn't break
anything, unless they touch some of the classes actually used. Ofcourse,
this is not to say that trying to minimize the bootstrap class-set isn't a
good idea, I'm just wondering how you'd do it in reality. I'm not sure
there are any programs that would do it automatically, at least if
reflection is involved.

Or maybe for release-use only; at least then you know any errors are
likely to have been introduced by the optimizer ;)
