Message        This declaration has type "<type>", which is invalid
                for a globalvalue.  The extern_model strict_refdef
                will be used instead.

 Description    An object with globalvalue storage class can only
                have a type of integer, enum, or pointer type.  In
                other cases, the compiler will change the storage
                class from globalvalue to strict_refdef.

 User Action    Change the data type to be one that is valid for a
                globalvalue.
