powerseries(1/sqrt(1+x),x,0)



Anyone have on older version of maxima (5.4 or so?) who can try out
powerseries(1/sqrt(1+x),x,0)?  Or maybe even a current maxima using
gcl.

Currently cvs maxima gets an error with this form.  If I fix the
offending places[1], maxima produces the same series as
powerseries(sqrt(1+x),x,0) produces.  I just want to know if old
versions for maxima or current versions using gcl produce the correct
result.  

I think the fix is ok, but I want to see if there are other issues if
I make that change.

Footnotes: 
[1]  I think the error comes from the fact that (caar 'atom) is NIL in
gcl, but is an error in other lisps.  I just added a check in a few
places before taking caar.
