getting auto generated normals from gluNurbus


I was wondering if there is an easy way to get back the auto generated normals from the gluNurbus tesselator? I know there is this extension


which allows you to do what I want, but I can’t find a Win32 implimentation of glu that supports this extension. Is there any other easy way of getting this information back, or do I have to make my own NURBS routines?

thanks in advance
