All my tests (on both older and newer autoconf/automake) succeeded. And
on irc doko said he thought the change was fine. So committed as:

2009-05-04  Mark Wielaard  <mjw at redhat.com>

  * autogen.sh: Lower requirements to autoconf 2.59 and automake 1.9.6.
  * configure.ac (AM_INIT_AUTOMAKE): Require 1.9 or higher.
  (abs_top_builddir): Explicitly define.
  (abs_top_srcdir): Likewise.
  (additional-vms): Rewrite help string and description.
  * missing: Remove generated file (autogen.sh).

Cheers,

Mark
