This macro is internal to gobject so using it risks breaking Cogl if glib changes its API. Instead we just use its expansion. Note that glib provides two expansions for this depending on the glib version but this only uses the one for older versions. Reviewed-by: Robert Bragg <robert.bragg@intel.com>
