Well, that's what it would say, whether it is an OS limitation or not. I 
just tried the following on Octave 3.6.2 / 64-bit Fedora 17:

a=rand(512,512);
for i=1:4196;
save -text -append a.txt a
end

and it writes a 5GB file just fine

-rw-rw-r--. 1 przemek przemek 5.4G Aug 28 15:59 a.txt

(I aborted it before it finished).

You didn't say how you write your file. Perhaps try what I did above and 
report how it went---perhaps there's some Windows runtime limit Octave 
runs into.
