  19.1 Distributing configure Scripts
  
       What are the restrictions on distributing configure
       scripts that Autoconf generates?  How does that affect my
       programs that use them?
  
  There are no restrictions on how the configuration scripts that
  Autoconf produces may be distributed or used. In Autoconf version 1,
  they were covered by the GNU General Public License. We still
  encourage software authors to distribute their work under terms like
  those of the GPL, but doing so is not required to use Autoconf.
  
  Of the other files that might be used with configure, config.h.in is
  under whatever copyright you use for your configure.ac. config.sub and
  config.guess have an exception to the GPL when they are used with an
  Autoconf-generated configure script, which permits you to distribute
  them under the same terms as the rest of your package. install-sh is
  from the X Consortium and is not copyrighted.
