+
+ * gtype.h:
+ * gparamspecs.[hc]: applied patch from owen to implement
+ GParamSpecUnichar.
+
+Fri Mar 30 07:34:02 2001 Tim Janik <timj@gtk.org>
+
+ * gtype.c (type_iface_retrive_holder_info_Wm):
+ * gtypeplugin.c (g_type_plugin_complete_interface_info):
+ * gtypemodule.c (g_type_module_complete_interface_info):
+ change order of instance_type and interface_type so they match
+ the g_type_add_interface_*() API.
+
+ * gsignal.c (g_signal_emit_valist): always assign C return value
+ location, people depending on unaltered return values after emissions
+ that had no handlers to run need to use g_signal_emitv().
+
+ * gtype.[hc] (g_type_query): new function to allow querying of
+ class and object size (semantics like g_signal_query()).
+ currently the implementation is better held conservative so as to
+ only support types that are classed and static.
+

* gobject.def: Updates.
