We got SUMacC version 2.0 (dated 11/84) today.  There are still a few old
bugs left:

1)

Subject:
	cc68 cannot cast to void.

Repeat by:
	try to compile
	main() { int a; (void)a; }
	this causes the compiler to loop.

Fix:
	Sorry, I don't have the sources so I can't fix it.

Temporary fix:
	#define void int


2)

Subject:
	CmpX doesn't work.  The stack isn't popped correctly.

Fix:
	Here's a context diff:
