Hello, Michael

It works! I have OpenGL 3.3 now. But there is a problem.

Here is a program I used to test OpenGL support:

https://github.com/afiskon/c-opengl-text

This is how it looks on Ubuntu, Windows and MacOS:

And this is how it looks on FreeBSD:

All DXT textures are rendered either black or white. I recognize this
behaviour because I observed it recently when I tried to run OpenGL
examples on VMWare:

Also note suspicious output from libGL.
