  It is argued that the presence of a nonanalytic term in the effective
potential of the Ginzburg-Landau model is immaterial as far as the order of the
superconductor-normal phase transition is concerned. To achieve agreement with
the renormalization group, the effective potential has to be extended to
include derivative terms, which provide the theory with a low momentum scale
which can be varied to probe the (possible) fixed point.
