Message        A storage class of globaldef, globalref, or
                globalvalue is a language extension.

 Description    These storage classes are language extensions of HP
                C.  Other C compilers might not successfully compile
                a program that uses the extension.

 User Action    These storage classes can be recoded using the more
                portable #pragma extern model.  <code_example>
                globaldef int var1; globalref int var2; globalvalue
                int var3; <endcode_example> Can be written as:
                <code_example> #pragma extern_model save #pragma
                extern_model strict_refdef int var1; extern int var2;
                #pragma extern_model globalvalue extern int var3;
                #pragma extern_model restore <endcode_example> For
                more information, consult the #pragma extern_model
                documentation.
