        <term><parameter>--without-ada</parameter></term>
        <listitem>
          <para>This ensures that Ncurses does not build support for the Ada
          compiler which may be present on the host but will not be available
          once we enter the <command>chroot</command> environment.</para>

      <varlistentry>
        <term><parameter>--enable-overwrite</parameter></term>
        <listitem>
          <para>This tells Ncurses to install its header files into
          <filename class="directory">/tools/include</filename>, instead of
          <filename class="directory">/tools/include/ncurses</filename>, to
          ensure that other packages can find the Ncurses headers
          successfully.</para>

      <varlistentry>
        <term><parameter>--enable-widec</parameter></term>
        <listitem>
          <para>This switch causes wide-character libraries (e.g., <filename
          class="libraryfile">libncursesw.so.&ncurses-version;</filename>)
          to be built instead of normal ones (e.g., <filename
          class="libraryfile">libncurses.so.&ncurses-version;</filename>).
          These wide-character libraries are usable in both multibyte and
          traditional 8-bit locales, while normal libraries work properly
          only in 8-bit locales. Wide-character and normal libraries are
          source-compatible, but not binary-compatible.</para>

    <para>This package has a test suite, but it can only be run after the
    package has been installed.  The tests reside in the
    <filename class="directory">test/</filename> directory.  See the
    <filename>README</filename> file in that directory for further details.
