 Message        <Context> a storage class modifier without a
                declarator is meaningless.

 Description    This message is generated when the compiler
                encounters certain declarations that contain a
                storage class modifier but no declarator.  For
                example:  readonly struct S { int a;};

 User Action    Either remove the storage class modifier or add a
                declarator to the declaration.
