Autoconf on-line manual not updated to 2.69

[Stefano Lattarini]

When I go to:

  <http://www.gnu.org/software/autoconf/manual/autoconf.html>

I see:

  This manual (21 September 2010) is for GNU Autoconf (version 2.68), ...

So the on-line manual hasn't been updated to Autoconf 2.69.  This is a pity,
especially because the new version of the manual documents a lot of new
portability issues with make and the shell.

Thanks,
  Stefano
