I've made -no-cpp-precomp the default in general. Chances are others 
broke gcc in the same way Apple did by turning the half-baked feature on 
by default before it was ready :)

Yeah, same here. I'm trying to wrap my head around it. Tim seems to 
generate part of the JIT from machine descriptions, which is a pretty 
cool idea.

I've figured out how to display kaffe.def in gdb (add its source dir to 
gdb's lookup path using the dir command) and how tu run gdb with 
jitBasic (turn the exec line into exec gdb in that shell script), so now 
I'm learning about jit3 & menmonicizer.awk in general. Now I just need 
to figure out which switch to toggle on to see the generated code :)
