I have done some little testing of gcj and kaffe. gcj should work
out of the box with gcc-3.2 release but doesn't have complete
library support.
Kaffe 1.06 required appended patch, didn't check if it was accepted
for 1.0.7 yet. It did feel pretty sluggish on a 68060 but that may
have been because of a gcc issue with long long arithmetic on this
CPU.
