 Message        <Context> the last member of a struct or union,
                <name>, has incomplete array type.  This is not
                strictly conformant with the C89 standard and might
                not be portable.

 Description    Compaq C will allow an array without a bounds
                specifier to be part of a struct or union type.
                While this extension is allowed by the C99 standard,
                other C compilers might not successfully compile a
                program that uses this extension.

 User Action    Specify the bounds if possible.
