        tests have been known to fail.  The

        <para>The <emphasis>math</emphasis> tests, at least on i686, fail in
        the <emphasis>test-double</emphasis> and <emphasis>test-idouble</emphasis>
        tests with gcc-&gcc-version;
        . These two failures in the math tests appear to be harmless.
        The math tests may also fail on systems where the CPU is not a relatively
        new genuine Intel or authentic AMD. Certain optimization settings are
        also known to be a factor here.</para>

        Modifying the make check command to set a TIMEOUTFACTOR is reported to
