Commit: Basil L. Contovounesios <contovob@tcd.ie>

    Pacify unused function warning in xfns.c with GTK2
    
    * src/xfns.c (x_get_net_workarea, x_get_monitor_for_frame)
    (x_make_monitor_attribute_list, x_get_monitor_attributes_fallback):
    [HAVE_XINERAMA] (x_get_monitor_attributes_xinerama)
    [HAVE_XRANDR] (x_get_monitor_attributes_xrandr)
    (x_get_monitor_attributes): Fix #ifdefs around definitions to avoid
    unused function warnings regardless of GTK use (bug#46509).
    [HAVE_XRANDR] (x_get_monitor_attributes_xrandr): Undefine
    RANDR13_LIBRARY after it's been used.
