  The O(alpha) electroweak radiative corrections to gamma gamma --> WW --> 4f
within the electroweak Standard Model are calculated in double-pole
approximation (DPA). Virtual corrections are treated in DPA, and real-photonic
corrections are based on complete lowest-order matrix elements for gamma gamma
--> 4f+gamma. The radiative corrections are implemented in a Monte Carlo
generator called COFFERgammagamma, which optionally includes anomalous triple
and quartic gauge-boson couplings in addition and performs a convolution over
realistic spectra of the photon beams. A brief survey of numerical results
comprises O(alpha) corrections to integrated cross sections as well as to
angular and invariant-mass distributions.
