I can't access this url right now, so I'm not able to verify what I'm
about to say.  (get an error page from webjump.com)

I'm curious what opengl implementation is included in 

    cygwin-xfree-4.0-cygwin-v-1.tar.bz2

I never did figure that out.  I think you are saying that it's SGI's
recently open-sourced GLX?  If so, I'm surprised that there is a libgl.a.
I didn't think GLX would build to something called libgl.a.

I had guessed that libgl.a is from mesa.  If that's true, whay is GLU
not included, too?  Does it not build, currently?  (I'm not very familiar
with mesa...yet)

I'm not sure how to read this.  What, exactly, is "wGL"?  I think
"OpenGL32" is the microsoft implementation?

I'm using microsoft's GL with glut, and no GLX.  My original post was a
mistake, as I've described in a different message.  Somehow, I missed that
the original poster was using Mesa, and not microsoft's OpenGL
implementation.

Suhaib, and the other people working on the cygwin-xfree86 project, thank
you for all your effort!
