You know some site to download an OpenGL 2.0 library (gl.h, glu.h, glx.h, gl.lib, opengl.dll, etc.)
In linux it works fine with NVidia drivers, only it is necessary to enable #define GL_GLEXT_PROTOTYPES in your code. However, in windows it is really poor, since is necessary the use of glew, glee, or another library to initialize the OpenGL 2.0 features.
