I added the files dlantr.f and zlantr.f to libcruft/lapack.  I think
that should solve your problem.  Or, I think you could also install
the Cygwin lapack package and run configure again so that Octave would
use that instead of the lapack files that are include with Octave.

If you do have the Cygwin lapack package installed and configure
didn't find it, then please look in config.log and see if that
provides any clues.
