If NeXT were to go to the Motorola 88k series any code with variable arguments is likely to break since the 88000 puts these in registers. How do you take an address of a register? You can't. I don't know if you could make a compiler smart enough to address this issue but in any case, I bet it wouldn't be easy. It would be wonderful to see a NeXT running with an 88000. __ / \ / __/_ /___/ __ /_ __ __ / INTERNET: robertl%bucsf@bu-it.bu.edu / \ '_' /_/ |_- / ' / BITNET: mete0pc@buacca.bu.edu
