2003-07-27  Tor Lillqvist  <tml@iki.fi>

	* gdk/win32/gdkevents-win32.c (build_key_event_state): On Win9x,
	the keyboard state returned by GetKeyboardState() doesn't
	distinguish between the left and right Control and Alt keys. Thus
	we cannot detect AltGr (which is supposed to be left Control +
	right Alt) the same way as on NT-based systems, but have to accept
	either Control + either Alt as AltGr.
