* Gio::Application:
 - Add back Gio::Application and friends so we can try to finish them.
 - local_command_line_vfunc(): Use references for parameters.
   See bug #643478.
 (Murray Cumming)
* Gio::TimeZoneMonitor: Remove because it was removed in glib.
 (José Alburquerque)
* Build:
configure: Require the latest libsigc++ because our tests require it.
