Are we going to include arpack sources in Octave? I'd prefer to leave
it as an external dependency unless there is some good reason to do
otherwise.

Both programs seem to work correctly for me. I also thought it might
be a buffer overrun that was only showing up on some systems (32- vs
64-bit pointers, for example) so I tried it on 32- and 64-bit sytems
and it worked on both. I also tried running it with valgrind and
there were no complaints for the call to dssimp. I'm using Octave
3.0.1 (64-bit system) and Octave 3.0.0 (32-bit system) on a Debian
system with arpack from the Debian package.
