Some of us may consider that no platform of importance exists in practice that breaks with such a cast, but our opinion does not matter at all, while opinion of those who supply compilers and checkers to us do---they may decide to flag such a use with a warning and that would break our build with the -Werror option. If we do not have to rely on the extension, we should. Thanks.
