Sat Nov 29 14:57:20 2003  Tim Janik  <timj@gtk.org>

        * gobject.c: fix g_object_set() whithin _init() implementations
        not working for construct-only properties.
        (g_object_init): make the object enter a construct_objects list.
        (g_object_newv): remove object from construct_objects after creation.
        (g_object_set_valist):
        (g_object_set_property): allow construct-only properties for
        objects which are in construct_objects.
