I ran the autoconf comand after the Octave autogen.sh script was
run.  The autogen.sh script is

  #! /bin/sh
  # autogen.sh
  # Run this to generate all the initial makefiles, etc.

  set -e

  AUTOMAKE="automake --warnings=no-portability"

  echo "generating source lists for liboctave/Makefile..."

  (cd liboctave; ./config-ops.sh)

  echo "generating doc/interpreter/images.mk..."

  (cd doc/interpreter; ./config-images.sh)

  echo "generating src/DLD-FUNCTIONS/module.mk..."

  (cd src/DLD-FUNCTIONS; ./config-module.sh)

  echo "bootstrapping..."

  ./bootstrap "$@"

The various config-*.sh scripts that are called by autogen.sh generate
some Makefile fragments that are mostly just lists of filenames and
some dependencies that are more easily managed if they are
automatically generated rather than created entirely by hand.

The bootstrap script is from gnulib. The bootstrap.conf file that it
requires is

  # Bootstrap configuration.

I'm working on a Debian system and using

The current Octave sources are in a Mercurial archive on Savannah:

  hg clone http://hg.savannah.gnu.org/hgweb/octave/

if you are interested in checking this out, then clone the archive,
run ./autogen.sh, then you should be able to run configure.

Thanks,
