A000621 G.F.: Conflicting Formulas

[Paul D. Hanna]

Seqfans,
       There is a conflict in o.g.f.s for sequence A000621:
http://www.research.att.com/projects/OEIS?Anum=A000621
 
They are given as: 
(1) G.f.: A(x)
=(1-x^2-x^8-x^4+x^10)/((x-1)*(x^9+2*x^8+x^7+x^6+x^5+2*x^4+x^3+x^2-1));
   
(2) G.f.: A(x) = 1/1 - x/1 - x^2/1 - x^4/1 -...- x^(2^k)/1-... (continued
fraction); 
or equivalently:  
G.f. satisfies: A(x) = 1/(1 - x*A(x^2)).
  
Formula (1) does NOT agree with the initial terms given, whereas formula
(2) does. 
  
Does someone have access to the references (see below) to determine what
is the correct g.f.? 
  
Thanks,
      Paul
