Yeah ... I'd love to see arm and mips pick up steam again, and if you
are interested in merging your improvements in (or Jari is interested in
making his patches go in, if some of his patches were dropped, too), you 
can surely get CVS access and improve arm and mips support.

Sparc seems to have held up nicely over the years, without requiring
much intensive maintainance (nicely meaning <3 regressions in general).
I don't know why, afair there was noone specifically maintinaing Kaffe
in shape on sparc in the last three years, but it seems to have worked
anyway. Mips and arm on the other hand seem to have been hit harder by
changes in the rest of the system. Off the top of ny head, I don't know
why that would be the case: mips and arm had a lot more interest in
patches and submissions on the lists than sparc did, afair.

That's the only one, afaict. Kiyo has been working on m68k jits as well,
though I don't have an m68k around to say how well those have stood the
test of time.

The rest would really need more maintenance, a switch to use libffi if 
available (seems to help with things on mips, and arm, for example), etc.
