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

 Message        The size of this structure is <size> bytes, which is
                not a multiple of its alignment of <align>.
                Respecify the alignment of the structure or add
                <bytes> bytes of additional padding.

 Description    The size of a struct or union is not a multiple of
                its alignment.  This could cause unaligned accesses
                if an array of these structs or unions is declared.

 User Action    Modify the struct/union or the alignment so that the
                size of the struct or union is a multiple of the
                alignment.
