  A simple scheme for avoiding non-spherical double counting in the combination
of density func- tional theory with dynamical mean-field theory (DFT+DMFT)is
developed. It is applied to total- energy calculations and structural
optimization of the pnictide superconductor LaFeAsO. The results are compared
to a recently proposed "exact" double-counting formulation. Both schemes bring
the optimized Fe-As interatomic distance close to the experimental value. This
resolves the long stand- ing controversy between DFT+DMFT and experiment for
the structural optimization of LaFeAsO.
