--- Comment #1 from Paolo Carlini <paolo.carlini at oracle dot com> 2011-12-16 14:38:40 UTC --- I don't think we should start warning each time an __attribute__((unused)) parameter is actually used. In my experience that's absolutely common and pervasive. If the parameter is meant to *never* be used, should be completely removed, no? Or maybe what you are really asking for are unnamed parameters, like in C++, which indeed can be handy sometimes when dealing with ABI stability issues, etc? Seems something different, however.
