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

 Message        <Context> "<name>" does not name a type.

 Description    This message is output when the compiler encounters
                an identifier that it believes is a typedef and no
                valid typedef by this name is defined in the current
                scope.  This most often occurs when there was an
                error in the declaration of the typedef name.

 User Action    Correct the declaration of typedef.
