The gcc manual page says about this topic:
    -Weffc++ (C++ only)
        Warn about violations of various style guidelines from
        Scott Meyers' Effective C++ books.  If you use this
        option, you should be aware that the standard library
        headers do not obey all of these guidelines; you can
        use grep -v to filter out those warnings.

So why don't you just use "grep -v" ?
