        * gtk/gtktypeutils.h:
        * gtk/gtktypeutils.c: enum and flags type creation can now be done
        through gtk_type_register_enum() and gtk_type_register_flags(),
        which allow to specify the enum value arrays directly.
        the NULL terminated value arrays can be retrived through
        gtk_type_enum_get_values() and gtk_type_flags_get_values();
