    17611761          <para>&CCL; uses an interface translation system based on the FFIGEN
    17621762            system, which is described at
     1763            <ulink url="">this page</ulink>
    17641764            The interface translator makes
    17651765            the constant, type, structure, and function definitions in a set of

    1776         the LCC C compiler to produce .ffi files. Since many LinuxPPC

    17771777        header files contain GCC-specific constructs, &CCL;'s
    17781778        translation system uses a modified version of GCC (called,
    17791779        somewhat confusingly, ffigen.)</para>
    1780       <para>A version of ffigen based on GCC-4.0 was developed
    1781         during the spring and summer of 2005.  Sources (diffs relative
    1782         to the GCC-4.0 release) are available here, and binaries are
    1783         available for DarwinPPC and for LinuxPPC.  These versions
    1784         should be insensitive to to the version of GCC (and its
    1785         preprocessor) installed on the system.</para>
    1786       <para>An older version was developed in 2001-2002; it depended
    1787         on the installed version of GCC being 2.95.  It may still be
    1788         of interest for people unable to run the GCC-4.0-based version
    1789         for whatever reason.</para>
