 *                                                    *
 * Checks value to be between min and max             *
 * return is value if check is successful, and err    *
 * if check fails                                     *
 *                                                    *
 * The checks are only made if the symbol:            *
 * BOUNDS_CHECK_ALL                                   *
 * has been defined, else the macro evaluates to      *
