I'll be honest, i have not bothered to understand your algorithm or data 
structures. You seemed to have things in control so I guessed they were 
fine. That said, fer sher, start only from symbols from headers of 
interest. Like a mark and sweep GC. Anything you do not reach does not 
need a binding.

I do not know, I fell asleep in my chair waiting. I am not kidding. :) 
So we definitely need to do something.

Great. I was not looking forward to coding all the needed exports for 
OpenGL. I could not believe how many I need from a small API like 
OpenAL, never mind my simple demo.
