NTEmacs 21.2.50 crashes

	* w32fns.c (mouse_move_timer, mouse_button_timer): Initialize.
	(menu_free_timer): New variable.
	(MENU_FREE_ID, MENU_FREE_DELAY): New constants.
	(w32_wnd_proc) <WM_TIMER>: Handle menu_free_timer.
	<WM_EXITMENULOOP>: Delay before freeing menu.  Do nothing if a
	menu command is in progress.
	<WM_COMMAND>: Set the menu_command_in_progress flag.  Kill
	any menu_free_timer that is running.

In the function w32_wnd_proc, WM_TIMER case seems to be missing an
initialization of f.  It crashes by referring to uninitialized f.
