Sam has done an excellent job elsewhere in this thread describing the incompatibilities between SSPI and GSS.  Many organizations have reported lack of support for out of order messages to Microsoft PSS as a show stopper issue over the last six years.

Martin does have a wrapper and Paul Leach of Microsoft was distributing it to customers for many years.  While it provides a significant degree of compatibility it can't overcome underlying weaknesses in the SSPI implementation.
