i.e. if GCC does not implement it yet we use elsewhere this kind of
marker instead:

     * Optional: not supported by gcc

The first of its kind, normally it is clang/icc there ;-)

We could nevertheless have the link there, something like:

    * Optional: not supported by GCC
                https://gcc.gnu.org/bugzilla/show_bug.cgi?id=80223
