Message        The CDD description for <name> specifies a data type
                not supported in C.

 Description    There is no VSI C datatype to exactly represent this
                type.  VSI C has created a declaration of the same
                total size as the unsupported data type.

 User Action    If the type provided by the VSI C compiler is not
                satisfactory, change the CDD description to one that
                the compiler can represent more exactly.
