wow, so except the m68k thing that was done more for fun a weekend but 
is perhaps not of such big interest (or does somebody runs gnustep on an 
embedded platform?) Sparc, ARM and MIPS would be of wider use.

I can look and test Sparc and MIPS (LE). Maybe we can do that on another 
rainy weekend, David? An excuse to dig out the sparc-asm.
Actually, I think I did implement it for the Kaffe Java-VM, I should 
look there.
