I don't think that's it.  A disassembly of XtWidgetCallCallbacks,
for example, (and not knowing the actual argument types)
shows the code is roughly:

	void XtWidgetCallCallbacks(a1, a2)
	int	*a1;	/* No idea what this type is really */
	char	*a2;
	{
		if (a1 == 0) return;
		XtCallCallbacks((?Widget?) &a1[2], a2);
	}

This code looks suspect as hell to me, yet it compiles to the
functional equivalent of what's in the R3 libXt.a.  The fact that
the third argument to XtCallCallbacks is missing is very strange.

Thanks for the 'go at it', though.
