    <para>We need to persuade <command>configure</command> that the host's
    compiler has all the necessary modern powerpc64 extensions.  It will still
    pass flags such as <literal>-mnew-abi</literal> which are likely to trigger
    error messages on a non-ppc host, but the headers can be built.  We do this
    by adding the following lines to <filename>config.cache</filename>. Note
    that one of these has three consecutive underscores.</para>
