In lieu of netlabs access, I've uploaded the current sources of GL/2 to the sourceforge repo. Access to netlabs is in the works; once it's been granted to me, I will upload the codebase to that repo. What's included in the codebase so far is:
All of the headers in my development tree, courtesy of the openwatcom group.
OPENGL.dll, which resides in the pgl directory.
To compile this code, you will have to place the codebase into a directory, then update the openwatcom project include path to point to the include folder that comes with the gl2 checkout.
