The thing I don't like about this form, is that it doesn't communicate
your intention, only your action.
Somewhere down my TODO list I have an item to propose instead:
typedef void unused_t;
int main(int argc, char **argv)
{
(unused_t)argc;
(unused_t)argv;
return (0);
}

Never attribute to malice what can adequately be explained by incompetence.
