Tor Lillqvist b1e744b064 Bug 544684 - Win64 issue, window handles are assumed to be 32-bit
2008-08-05  Tor Lillqvist  <tml@novell.com>

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

	* gdk/gdkdnd.h
	* gdk/gdkdnd.c
	* gdk/win32/gdkdnd-win32.c
	* gdk/x11/gdkdnd-x11.c: Change return value and type of window id
	from guint32 to GdkNativeWindow for
	gdk_drag_get_protocol_for_display() and
	gdk_drag_get_protocol(). This is not an API break on existing
	platforms, as GdkNativeWindow has been guint32 for them
	already.
