 Message        <Context> <noshare or readonly> cannot be used with
                the typedef storage class.  Modifier is ignored.

 Description    The storage class modifiers noshare and readonly are
                meaningless for typedefs.  The compiler ignores the
                storage class modifier.

 User Action    Remove the storage class modifier.
