Why is (void)&variable; construct used?

[Max Okumoto <okumoto@xxxxxxxx>]

With the new gcc do we still need the following construct?


        /*
         * Avoid clobbered variable warnings by forcing the compiler
         * to ``unregister'' variables
         */
#if __GNUC__
        (void)&av;
        (void)&errCheck;
#endif
