        * gtk/gtkmain.c (gtk_main): added gdk_flush() after g_main_run(), so we
        get the original behaviour back, i.e. the event queue needs to be flushed
        after a main loop has been quitted.
        (gtk_main): add/remove the current main loop to/from the main loop
        before/after init/quit functions have been exected to preserve the
        original gtk_main_quit() behaviour.

        * gdk/gdkevents.c (gdk_events_init): changed argument order in call
        to g_main_add_poll() to match recent glib changes.
