The following is installed on the system I have access to:

  $ ifort -V
  Intel(R) Fortran Itanium(R) Compiler for Itanium(R)-based applications
  Version 8.0   Build 20040716 Package ID: l_fc_pc_8.0.046_pl050.1
  Copyright (C) 1985-2004 Intel Corporation.  All rights reserved.

  $ uname -a
  Linux XXX 2.4.21-sgi304r1 #2 SMP Wed Mar 30 16:12:04 EST 2005 ia64 ia64 ia64 

I built from the current CVS files earlier today with the commands

  configure --enable-64 F77=ifort FFLAGS="-i8 -O"

This is on a system without ATLAS or other fast blas/lapack library
installed.  The resulting binary is linked against the following

It passed failed 4 of the 1207 tests run by make check:

  FAIL: octave.test/io/load-save.m
  FAIL: octave.test/linalg/qr-7.m
  FAIL: octave.test/matrix/rand-1.m
  FAIL: octave.test/matrix/randn-1.m

It's not surprising that it failed the load-save test since load and
save are not completely working for 64-bit systems.  Probably rand
failed because ints in the Fortran random number generator are
expected to be 32-bits wide, or because of some other initialization
problem (I see that it works when I run the test interactively).  The
The qr test is failing the accuracy test at the end of the qr-7.m
