I am learning X Window and have just found out that MIT borrowed the
Cardinal type from Pascal.  Now in order to avoid all kinds of
warning messages, I have to declare my variables like argc to be
either of type Cardinal, unsigned int, or u_int(the way I used to
declare non-negative numbers).  This might seem like a minor detail, but
three different ways to say something is a too much!  Which style is
the more acceptable?  Imagine teaching someone C or C++ and having to
explain to them why there are three names for numbers that are
non-negative.  Maybe you could tell them that C (C++) is a language where
everyone does their own thing.

------------------------- The problem illustrated -------------------------

main(u_int argc, char* argv[])
{
	
	// XtAppInitialize() expects argc to be a Cardinal number
	.
	.	
	.

    toplevel = XtAppInitialize(&app_con, "Xhw", NULL, ZERO, &argc, argv,
			       fallback_resources, NULL, ZERO);

	.
	.
