	Earlier I suggested getting the XmNiconic resource of the
toplevel shell, but this does not seem to work. On the other hand,
at least under mwm (Motif 1.1, Sun-3), the toplevel shell is unmanaged 
when iconified. The following timer callback checks iconification
using both methods every 5 seconds. The toplevel shell is obtained
via MrmFetchWidget. The first method always prints out that the top
widget is not iconified. The second method correctly identifies whether
it is iconified.
	HOWEVER. I have a sneaking suspicion that this may be
dependent on the window manager, so use with caution.

{
	Widget	top= (Widget)client_data;
	Arg	arg[1];
	Boolean	is_iconic = 1;

/* Method 1: doesn't work under mwm */
	XtSetArg(arg[0], XmNiconic, &is_iconic);
	XtGetValues(top, arg, 1);
	printf("I am%s an icon?\n", is_iconic ? "" : " NOT");
/* Method 2: works under mwm */
	printf("I am%s an icon!\n\n", XtIsManaged(top) ? " NOT" : "");
	XtAddTimeOut(5000, CheckIconify, client_data);
}
