-   tjump@spgs.com contributes:
-   If users are building glut code on MS Windows, then they should
-   make sure they include windows.h early, let's not get into a
-   header definitions war since MS has proven it's capability to
-   change header dependencies w/o publishing they have done so.
-
-   So, let's not include windows.h here, as it's not really required and
-   MS own gl/gl.h *should* include it if the dependency is there. */
