As requested.

[C_Polyhedron.ii.bz2 attachment] Some header file different from reg.h is defining the macro CS to 15. You should discover which one is doing that. Good luck, Roberto

As I've already stated if you wish you can pursue this on your own merely by downloading either an OpenSolaris, Solaris, or Solaris Express DVD or Live CD and then you can investigate it to your hearts content.

I have absolutley zero interest in persuing the matter.
