If anyone's interested in the OpenGL replacement mentioned on that page, there are 2 other candidates similar to tinyGL. There are picogl and sdl-tinygl. The Syllable forum ( http://forum.syllable.org/viewforum.php?f=1 ) has some interesting information about all three of these and makes some comparisons. If I remember, one of them has a subset of the glut functionality included. I believe some porting is typically needed to use any of them as a replacement for OpenGL. Speaking of glut, freeglut ( http://freeglut.sourceforge.net/ ) seems more portable and up-to-date than glut.
