--- Comment #13 from Martin Sebor <msebor at gcc dot gnu.org> ---
Let me confirm this request.  I think diagnosing even just the simple cases
would be worthwhile.  The -Wsuggest-atribute= option isn't perfect either but
it is presumably useful nonetheless, as are many other warnings that are
similarly limited and prone to both false negatives and false positives.
