We're going to try to put in 32 bit binary compatibility so current 32 bit apps should run on the 64 bit kernel without a recompile. I think there's only potential trouble for someone who would recompile Kaffe for the 64 bit kernel... but that doesn't exactly quite exist yet... > > Work has started on the 64 bit PowerPC Linux kernel, if Kaffe is compiled as a > > 64 bit app for that kernel then sizeof(unsigned long) = sizeof(void *) will be > > true.

While I can't promise machines, it is possible to get a few out there here and there.... Regards, Tom -- Tom Gall - PowerPC Linux Team "Where's the ka-boom?
