I try to compile the source package by myself.
There are two things I found.
1) No appropriate function for "atan( 1 )"
2) wglext.h can not be found

The compiler is VS .NET 2003, and work on XP.
Because no related subject for this in readme.html, I post this here.
1) Modify "atan(1)" to "atan(1.0)".
2) download GLsdk.zip from from http://oss.sgi.com/projects/ogl-sample/sdk.html
