I have not tried cvs version of ecl, but I suspect the zeta stuff is
caused by the fact that (expt 2 #c(1d0 0d0)) only gives single-float
precision instead of double-float.

I think it would be nice if ecl returned double-float precision for
this, but I don't think it's required by ANSI.  However, clisp, cmucl
and gcl do, and ccl will (changes applied but not updated),  I have
heard sbcl will too.

I'd rather not work around this in maxima, but if necessary, I guess
we'll have to.
