VMS Help CC, Messages, UNKPSECTATTR  *Conan The Librarian (sorry for the slow response - running on an old VAX)

 Message        Unknown psect attribute for extern model.  Attribute
                is ignored.

 Description    A psect attribute specified in a #pragma extern_model
                is invalid.  In general, the psect attributes
                accepted by Compaq C/C++ match those accepted by the
                assembler.  The psect attribute will be ignored.

 User Action    Correct the psect attribute.
