Ben,

I tried gprogram also:

On this pf3.1 linux machine:
OpenGL renderer string: Quadro4 900 XGL/AGP/SSE2
OpenGL version string: 1.4.1 NVIDIA 53.36

...I get the same result: only multicolored cubes.

On this pf3.1.1 IRIX onyx4:
OpenGL vendor string: ATI Technologies Inc.
OpenGL renderer string: Fire GL X1 (FireGL)

... I get three types of shading:
- unlit purple,yellow,blue like above
- unlit blue
- unlit green

I am not sure what effects the author of gprogram.C intended.
