I enclose a gzipped copy of the Makefile after the modification. Could you 
tell me if I did ok please?

Oh, please do, from my experience with other emulators that used JIT - it's a 
great thing...

Well, right now I'm in the middle of testing a better kernel for my needs. 
2.4.17 sucks when you heavy overload it. Seems like 2.4.18-pre3-ac2 can do 
the job, still testing...

Oh? I thought that they did heavy optimization and made it proprietary. The 
Amithlon 68k engine is wildly fast - it's showing like 1Ghz 68040 processor. 
Do u think your JIT can achive this performance????

Makefile (gzipped) enclosed.
