Hi Fredrik,

We at the High Performance Computing Support Unit at the University of 
New South Wales have ported Octave (v.2.1.57) to 64 bits on an SGI 
MIPSpro platform (should be quite protable). This has not been absorbed 
to the main octave code base at octave.org yet. However, we can make our 
version (based on v.2.1.57)available to you for further testing. We are 
working on merging with the 2.1.64 version now.

We have ran through the test-suite that came with Octave, and our 64bits 
seem to pass the tests. You may need to test it out yourself to verify 
64bit-readiness. I don't think we use specific MIPSpro C++ code so it 
should be portable to Solaris. There may be one or two lines in the 
configuration file that need to be changed - that's all.

Cheers,
Clinton Chee
