Subject: [PATCH] - Un-implement NtUserDispatchMessage. - First of all, it is
 incorrect. I had a rant that I was going to send to the private mail list,
 but this will do. - No more "New Standards"! The Window object should already
 know it is ANSI or not. A pointer to MSG is the only thing passed.
