Actually, both goals are complementary, afaict. I mean, you can have a
single core class library shared betwen the runtimes, and some runtimes
overriding bits and pieces as they need it.

My plan is to emulate Tom, whenever I can :)

The idea would be after 1.1.6 to roll in the classpath check out into
Kaffe and then see how I need to tweak Kaffe's build system to deal with
it. It should not be that hard, it just hasn't been done until a few
weeks ago in gcj, and I wanted to see how it works out first. Breaking
Kaffe's build system is something I do regularly and with passion, but I
wanted to avoid it while I was dragging in bits and piecses for the next
release. Still a few patches to go there, but it's almost ready.

I'd also eventually like to merge in gcjx into kaffe, since the jikes
situation is detoriorating rapidly (crashes going unfixed) on odd
architectures, and I'd prefer to feed bug reports into a maintained
compiler :) I've written up how to build kaffe's class lib with gcjx,
and those writeups should also be gone, once it's all switched over :)
