Does the output have PSPP code in it?  To be a derivative work,
it would have to contain PSPP code, as I understand copyright

I was expecting the output to mostly be a bunch of numbers, with
a little bit of C wrapper code.  We don't try to GPL other
numbers that PSPP outputs.

I don't think that's true in general.  PSPP outputs PostScript
programs as output, but that's clearly not GPL'd.  Autoconf
outputs shell programs, but those aren't GPL'd (they have a very
permissive copyright notice).  The output of Bison is sometimes
GPL'd, but only when it contains part of Bison itself.
