HAVE_FSEEKO is defined by the AC_FUNC_FSEEKO automake macro.
 We trust
it won't be defined if the macro detects it is not defined
properly in the
system headers and included in the C library.

You need HAVE_FSEEKO _and_ -D_LARGEFILE_SOURCE.
AC_FUNC_FSEEKO only
defines HAVE_FSEEKO, though, during testing in ./configure,
it sets
-D_LARGEFILE_SOURCE to expose fseeko/ftello. But, it doesn't
set
_LARGEFILE_SOURCE.

The problem is that AC_FUNC_FSEEKO is buggy with
autoconf-2.61. A fix
was put in after 2.61 and is available in CVS. For info on
the bug,
see Debian bug id:
  http://bugs.debian.org/
401377
and the following autoconf changelog entry:
  2006-12-04  Paul Eggert  <eggertcs.ucla.edu>

          * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO):
Check that fseeko
          can be assigned to a function pointer.  Problem
reported by
          Peter Palfrader in <http://bugs.debian
.org/401377>.  Based on
          part of a patch by Ralf Wildenhues in that same
bug report.
