	I posted a similar question not too long ago, so it's likely that
	you're having the same problem that I had.
	Anyway, what I was doing wrong was using EMM386 with its default
	256 kb of expanded memory, so when go32 runs, it uses the expanded
	memory instead of extended memory. As a result of the small amount
	of memory (<256kb) it does a lot of swapping and slows down.
	When you're using a Windows dos box, Windows provides all the 
	DPMI memory that is available, which is about 2-2.5 MB looking at
	your configuration of 8 MB, also depends on what you've got running at
	the same moment.
	I just got rid of EMM386 and loaded everything low but I now have
	a lot more extended memory for go32 so gcc compiles faster. Hope 
	this helps.
