The code is basically the same as before, but with your proposed changes and the GLEW_STATIC stuff. This example does work perfectly well on my Windows machine; the glClearBufferfv is a newer function than glClear and glClearColor. Those two I'm already familiar with, and they work on my Mac without the GLEW stuff.
