I finaly managed to answer my own question.  It turns out GtkItemFactory 
assigns eaxh radiomenubutton its own seaprate group so you have to change 
this so the ones you want grouping are in the same group.  the way this is 
done is similar to grouping radiobuttons but you have separate functions to 
get and set the group.  So I wrote a function that appends a radiomenu button 
to a group:


GSList * appendmenuradiobutton(GtkItemFactory * factory, const gchar * path,
 GSList * group, gint check)
{
        GtkWidget * aradiobutton;

        aradiobutton = gtk_item_factory_get_widget(GTK_ITEM_FACTORY(factory), path);
        gtk_radio_menu_item_set_group(GTK_RADIO_MENU_ITEM(aradiobutton), group);
        gtk_check_menu_item_set_active(GTK_CHECK_MENU_ITEM(aradiobutton), check);
        return(gtk_radio_menu_item_group(GTK_RADIO_MENU_ITEM(aradiobutton)));
}

You pass this the factory, the path to the radiomenubutton, a GSList pointer 
and TRUE/FALSE to determine if it is initialy checked or not.  To group three 
radiomenubuttons just:

GSList * group;

group = NULL;
group = appendmenuradiobutton(GTK_ITEM_FACTORY(factory), 
"/pathtofirstradionbutton", group, TRUE);
group = appendmenuradiobutton(GTK_ITEM_FACTORY(factory),
 "pathtosecondradiobutton", group, FALSE);
group = appendmenuradiobutton(GTK_ITEM_FACTORY(factory),
 "pathtothirdmenubutton", group, FALSE);

Hope someone finds this useful.  Maybe it should even appear in the gtkref??
