My turn to move:

   address@hidden:~$ octave
   Octave, version 1.1.1.

   octave:1> x = nan
   x = NaN
   octave:2>

This is the Linux pre-compiled binary from ftp.che.utexas.edu, directory
pub/octave/BINARIES. Clearly there is a problem with the above version
on the DEC. As you can see, it can work, so in principle it should work.

Time for others to join in, I think.
