That would be surely better.  Actually, in the specific case I had in
mind (NaN problem on mips/mipsel) there would be no need to compare the
output, just to exercise the code in pr-output.cc.  So, the test could
be, for now:

/* 
%!test
%! format short
%! file = tempname ()
%! fd = fopen (file)
%! for r = [0, Inf -Inf, NaN]
%!     for i = [0, Inf -Inf, NaN]
%!         fdisp (fd, complex (r, i))
%!     endfor
%! endfor
%! fclose (fd)
%! unlink (file)
*/
