No, that would have been far too clever.

What about this instead:

Subject: [PATCH] Fix unused function warning in xfns.c with GTK2

* src/xfns.c (x_get_net_workarea): Define only when using GTK other
than GTK3, or when not using GTK, to match its use in
Fx_display_monitor_attributes_list.
(x_get_monitor_for_frame, x_make_monitor_attribute_list)
(x_get_monitor_attributes_fallback, x_get_monitor_attributes_xrandr)
(x_get_monitor_attributes_xinerama, x_get_monitor_attributes):
Condition definitions on !USE_GTK, to match their use in
Fx_display_monitor_attributes_list (bug#46509).
(x_get_monitor_attributes_xrandr): Undefine RANDR13_LIBRARY after
it's been used.
