--- Comment #2 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
The problem is caused by the move of check_global_declaration* into cgraph; the
problem is that these decls that are never used are simply never added to the
cgraph.
Trying to emit this warning at the end of c_write_global_declarations_1 (if a
decl satisfies those conditions and does not have a cgraph node, emit warning)
might be ok, unless there is the possibility that a cgraph node would be
created for it later on.
