    If you look at, ltconfig, config.guess, config.sub
    which basically form libtool, you will notice this clause:

    # As a special exception to the GNU General Public License,
    # if you distribute this file as part of a program that
    # contains a configuration script generated by Autoconf, you
    # may include it under the same distribution terms that you
    # use for the rest of that program.

    The same clause appears in the generated libtool shell
