I filed a bugreport on the dglopengl header using string instead of pglchar.
With a quick change on the local copy of it i now get correct answers 1 and 0.

With the c source not using vertex array object i asumed that to be optional, so tomorow i do a rewrite including them also.

But should not opengl 3.x work the same regardless of your videocard being ati or nvidia? I do not want seperate code paths.
