	Actually fixhdr -F xxxx or cc -F ...  Anyway, on the 286 the 
	stack _is_ fixed in size and often needs the stack extended past
	3000 (hexadecimal, which is what the -F option expects).

	My experiences are equivalent.  Everything was working until I
	upgraded the DS to 2.3, then all hell broke loose.  DS 2.2 is
	equivalent to Microsoft C 4.x whilst 2.3 is Microsoft C 5.x.
	I at least knew how to work around the bugs in 2.2.  I also
	found some funny shift stuff that needed attention so I had to
	patch around that with an assembly language routine.  I also
	discovered that in grafting on 386 code generation into the
	C compiler, Microsoft's ability to generate usable 286 code
	got pretty bad.

	Using Microsoft and working in the same sentence can get you
	lynched.  Like Intel, Microsoft can't get the first 7 revisions
	(or steps) of a product to work without bugs.  Funny, isn't it,
	that Motorola's chips always work correctly?

--	Flame Off!

	Please forgive the flames.  I spent about 2 years working on the
	internals of Thoroughbred BASIC and had to make it work on both
	286 and 386 boxes.  I consider myself lucky that I didn't pull
	DOS duty...
