Bug 544684 - Win64 issue, window handles are assumed to be 32-bit

	Bug 544684 - Win64 issue, window handles are assumed to be 32-bit

	* gtk/gtkwindow.h
	* gtk/gtkwindow.c: Change the type of the xid parameter of the
	internal gtk_window_remove_embedded_xid() and
	gtk_window_add_embedded_xid() functions from guint to
	GdkNativeWindow.

	* gtk/gtkwindow.c (send_client_message_to_embedded_windows):
	Instead of GPOINTER_TO_UINT(), just cast the gpointer to
	GdkNativeWindow. GPOINTER_TO_UINT() drops the upper 32 bits on
	Win64.
