+Subject: [PATCH] gdk: add a "poison" macro to hide GDK_WINDOWING_*
+
+Many packages perform automagic dependencies on gdk's backend
+implementations by checking if the macro is defined and then using the
+code it unlocks, rather than having a buildsystem option such as
+-Dwayland=true.
+
+It's unfeasible to patch every such package's source code to add
+configure options and respect them. Instead add a truly filthy hack and
+permit gtk itself to selectively show or hide the windowing system in
+use.
+
+By default, we assume this macro is never defined. It should only ever
+be defined inside an ebuild, as such:
+
+```
+use wayland || append-cflags -DGENTOO_GTK_HIDE_WAYLAND
+use X || append-cflags -DGENTOO_GTK_HIDE_X11
+```
+
+When seen, this will prevent code using "#ifdef GDK_WINDOWING_*" from
+seeing the define, so the automagic dependency won't be picked up. It
+will also cause any attempt to #include the backend-specific headers to
+bug out.
