I see. Looking a bit further, it looks like the C FE uses cfun->language only to store the context of the outer function when faced with a nested function. This is done by c_push_function_context, called by c_parser_declaration_or_fndef. Otherwise, cfun->language is not allocated. Is it appropriate that -Wunused-local-typedefs allocates it as well? -- Dodji
