Hi,
I was poking around with the arcsynthesis GL tutorials and wanted to try coding them up in Lisp with SDL2. I was able to get the first tutorial running on Linux, but when I try to run it on Windows, I get an error when calling gl:create-shader. Specifically, SLIME breaks into:
NIL is not of type (OR SYMBOL FUNCTION), and can't be FUNCALLed or APPLYed [Condition of type TYPE-ERROR]
Is there something special that needs to be done for loading extensions on Windows? The shader-vao sample runs for me, but I can't determine if GLUT is doing something special or not. I can't wholly rule out that I've done something silly, so I've attached the source.

This is the special bit that GLUT does:
;; https://github.com/3b/cl-opengl/blob/master/glut/init.lisp#L60 (setq %gl:*gl-get-proc-address* 'get-proc-address)
SDL should have something similar to glutGetProcAddress().
