This problem has been discussed before. Search the mailing list archives through the link on the left of http://xfree86.cygwin.com/.
I believe the problem is that SGI's GLX is unique in flavor.

Dear All,
I have an application that sits on an SGI machine which I access via xfree86 on cygwin. When I try and open the application, I get a message telling me that "extension GLX" is missing. I have cygwin's OpenGL installed but I am guessing that the GLX extension is not part of this distribution. Is there a GLX extension for cygwin? If not, does anyone know of an X-windows environment for Microsoft Windows which supports GLX?
Thank you for any advice you can give!
Ed.
