--- Comment #19 from Jan Hubicka <hubicka at ucw dot cz> --- Yeap, the warnings was written at the time all C++ types had TYPE_NAMEs and other types used IDENTIFIER_NODE. I have chnaged it for memory use reaosns so only main variants have IDENTIFIER_NODE. Usually we want to just look for main variant and complain about that. I will look into it. Honza
