Details:

I can confirm that there is an issue making the 64-bit build of version 4
(from ftp://ftp.gnu.org/gnu/octave). 
3.8.2 however builds ok for 64-bit and GUI (octave --force-gui). 

 
>> a = zeros (1024*1024*1024*3, 1, 'int8'); 
error: out of memory or dimension too large for Octave's index type

we run (./configure --prefix=/prog/rdtoolbox/octave/versions/3.8.1-RHEL6
--enable-openmp --enable-64 F77_INTEGER_8_FLAG=-fdefault-integer-8) this
command. As a result we end up with the below error. To fix the below error we
followed the instruction provided in the site (http://wiki.octave.org/MXE). 
========================= 
configure: error: BLAS doesn't seem to support 64-bit integers. This is
incompatible with --enable-64.
