I think that Andreas just hacked up some code that parsed the OpenGL 
headers, but wouldn't work in general because of different typedefs in 
the headers, etc.  This is what I did to auto-generate FFI calls for 
Cg.  Check my CgCroquet package on SqueakSource; I include the class 
that I used to generate the methods.
