	The compiler miscalculates the argument stack offset for far
_saveregs functions by two bytes.  This is surprising since _saveregs
far pascal functions are the most likely definitions for OS/2
entry points and would presumably have been tested.

Repeat by:

_saveregs far
foo(a, b, c, d)
{
	printf("%d %d %d %d\n", a, b, c, d);
}

main()
{
	foo(1, 2, 3, 4);
}

Remove the _saveregs or the far and note the difference.
