Ok - Why though? Maybe I am too naive with this but can't this be
automated as well? AFAIK you have to expose the enumerations and the
functions, both of which you have access to from the specs, no?

Whoa - I wasn't expecting that... Testing that the extension is callable
is part of the build process?  I would think that having the function
ptr exposed would be all you'd need to do.

Gotcha -- Makes sense. Just use the extensions instead of the core.

I don't think they're doing any new OGL drivers other than 1.1 AFAIK

Unsuredly-yours,
