I can do this when I get home but at present I am abroad.  This is on a
Thinkpad Z61M running Debian (unstable). The machine at home is also
i386, Athlon processor, running the same software. I've only installed
32-bit stuff.

I will try your suggestion when I get back. It's annoying that my
attempt to compile SP on this machine doesn't work. Not sure why --
something to do with the gcc version I think.
