With Autoconf version 2.60 or newer, htmldir is already predefined by
Autoconf.  It's really the AC_INIT code that predefines it.  The NEWS
file of the Autoconf source distribution mentions this, and the manual
lists it here:
<http://www.gnu.org/software/autoconf/manual/html_node/Installation-Directory-Variables.html>

Here's what you can do:
- ignore the warning or hide it by passing -Wno-override to automake
  (by adding it to AUTOMAKE_OPTIONS in doc/Makefile.am for example)
- not using your own definition of htmldir any more with new Autoconf
  (you should check if Autoconf's setting and yours are compatible)
- use a different directory variable (html2dir, doxgenhtmldir, together
  with doxgenhtml_DATA or so...)

Hope that helps.

Cheers,
Ralf
