      	GTK+ 2.0 the GtkWindow struct actually is the same size in gcc on
      	Win32 whether compiled with -fnative-struct or not. Unfortunately
      	this wan't noticed until now. So, from now on, check some other
      	struct, too, for which the use of -fnative-struct still
      	matters. GtkBox is one such.

      2001-06-07  Havoc Pennington  <hp@redhat.com>
      
      	* atk/Makefile.am: use @GLIB_GENMARSHAL@ so we can use uninstalled
      	glib-genmarshal
      
      	* configure.in: rearrange the library checks to support
      	uninstalled linking

      	to override the way values are drawn.
      	(gtk_scale_get_value_size): fix width/height mistake,
      	and compute size from actual displayed text, not
      	from made-up text.
      
      	* gtk/gtktexttag.c (gtk_text_tag_class_init): fix return type in
      	signal registration
