broken link in autoconf online html documentation

[Stefano Lattarini]

Hi everybody.

I'm not sure if this is the right place to report this, but it seemed 
the most appropriate IMHO.

I found a broken symlink in the online html versions of the autoconf 
manual, more precisely:

* the link `Compatibility' at the bottom of the page
  http://www.gnu.org/software/autoconf/manual/html_node/Shellology.html
  (in the "Zsh" subsection).

* the similar link `Compatibility' at the url
  http://www.gnu.org/software/autoconf/manual/autoconf.html#Shellology
  (in the "Zsh" subsection).

Regards,
    Stefano
