From eacf409f1f3246731f27100d5a927eb5820dfa80 Mon Sep 17 00:00:00 2001
From: Jason Rumney <jasonr@gnu.org>

Subject: [PATCH] Reorder to match x-win.el more closely.
 (x-setup-function-keys): Use local-function-key-map. (w32-initialized): New
 variable. (w32-initialize-window-system): Set it. Move more global setup
 here.
