You could try my patched version of cl-opengl at
http://www.3bb.cc/tmp/cl-opengl-3b.tar.bz2
It should work on Win32, and includes OpenGL >=1.2 functions and most
of the GL extensions that are more than a month or 2 old. The examples
will require GLUT, but the extension code should work with
wglGetProcAddress, or SDL's version, or whatever. Just need to add the
appropriate defcfun and  (setf
cl-opengl-bindings::*gl-get-proc-address* #'wglGetProcAddress) at some
point before you try to call any GL>=1.2 or extension functions.

I've run some of the examples on win32 SBCL, but not really stressed
it much. I assume it won't work on Corman, since it needs
foreign-funcall, but should work on other CFFI supported lisps.
