To learn more about what is going on here, I built both PSPP
0.4.0 and the latest version from CVS on pergolesi.debian.org in
a 64-bit chroot.  On "make check" on 0.4.0, about half of the
tests failed.  With the latest CVS snapshot, however, all tests
passed, and the example program worked fine.

I don't think that PSPP 0.4.0 is going to perform satisfactorily
on x86-64.  The upcoming release, and the current CVS for that
matter, should be much better.

(I am currently fielding a few problems with support for
big-endian systems though.  But those should be pretty easy to
