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?
