    Might also mention that (in pursuit of the truth 8-*) 
    I have tried the lint /*VARARGS*/ flag, both just 
    before the invocation of my call to WigetSet() as well
    as just before the routine that contains the WidgetSet call.
    Neither made a difference. Both my program,  
    and the actual PD WidgetSet() routines, see
    NULL defined as a zero.

    The calls to WidgetSet() are setup along these lines:

    static Widget
    do_it(parent)
       Widget parent;
    {
       Arg   al[25];
       int   ac = 0;
       Widget ...;
       ... 
       XtSetArg(al[ac], ....);
       ac++;
       (Widget) mytextwidget = DwtSTextCreate(parent, "mylabel", al, ac);
       WidgetSet(mytextwidget,
	         DwtNfocusCallback,      my_callback,
	         DwtNadbTopAttachment,   DwtAttachOppWidget,
	         DwtNadbTopWidget,       abovewidget,
	         DwtNadbLeftAttachment,  DwtAttachWidget,
	         DwtNadbLeftWidget,      abovewidget,
	         DwtNadbRightAttachment, DwtAttachAdb, 
                 NULL);
       XtManageChild(mytextwidget);
       ...
    }
