Wed Aug 23 10:35:32 2006  Tim Janik  <timj@gtk.org>

        * gobject.[hc]: changed return value of g_value_dup_object(), fixes #343292.

2006-08-23  Sven Neumann  <sven@gimp.org>

        * gobject/glib-genmarshal.[c1]: added new command-line option
        "--internal" that can be used to let glib-genmarshal generate
        internal functions using the G_GNUC_INTERNAL attribute (bug #346647).
