1.0.b3 on Sparc and m68k

[Kiyo Inaba]

I've tested (old and slow but) stable interpreter version on m68k.

On m68k/NetBSD 1.3.1/gcc 2.7.2.2+myc1/intrp/unix-jthreads
	pizza works fine.
	The pgrp problem remains.
	CLTest made FileNotFoundException in Hello.class.
	GCTest runs infinitely.
	Overflow dumps core with illegal instruction.

So the pizza problem may be caused by the conjunction of jit
and jthreads.
