        If <command>clang++</command> is available, it will be used in the
        mistaken belief that <command>g++</command> might not support C++11,
        even though <command>configure</command> has tested for that.  If
        using <command>g++</command> there will be an unnecessary warning at
        the end of <command>configure</command>.  Building with
        <command>g++</command> also takes longer than the estimated SBU shown.
