    <para os="a">This package and the next two (Expect and DejaGNU) are installed
    to support running the test suites for GCC and Binutils. Installing
    three packages for testing purposes may seem excessive, but it is very
    reassuring, if not essential, to know that the most important tools are
    working properly. Even if the test suites are not run in this chapter
    (they are not mandatory), these packages are required to run the test
    suites in <xref linkend="chapter-building-system"/>.</para>

    <para os="b">Prepare Tcl for compilation:</para>

<screen><userinput>cd unix
./configure --prefix=/tools</userinput></screen>

    <para os="c">Build the package:</para>

<screen os="d"><userinput>make</userinput></screen>

    <para os="e">To test the results, issue: <userinput>TZ=UTC make
    test</userinput>. The Tcl test suite is known to experience failures
    under certain host conditions that are not fully understood.
    Therefore, test suite failures here are not surprising, and are not
    considered critical. The <parameter>TZ=UTC</parameter> parameter sets
    the time zone to Coordinated Universal Time (UTC), also known as
    Greenwich Mean Time (GMT), but only for the duration of the test suite
    run. This ensures that the clock tests are exercised correctly.
    Details on the <envar>TZ</envar> environment variable are provided in
    <xref linkend="chapter-bootscripts"/>.</para>
