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

 Message        The use of a designation in an initializer list is
                not supported in this compilation mode.

 Description    Initializer lists that contain designations are a new
                feature in the C99 revision of the C standard.
                Compaq C will only support this extension in relaxed
                mode and strict c99 mode.

 User Action    Use a compilation mode that supports the use of
                designations.
