   As far as I know, the cgnine was never supported by OpenWin. There's a
note in the FE manual that it isn't supported in OpenWin 2, and I've heard
from folks running 3.x that it isn't supported there either.

   Actually, the P4-based 24-bit cgeight is supported in X11R6. The patch
to support cgnines gloms onto the cgeight code since they're fairly close
(if you ignore all the acceleration hardware on the cgnine *sigh*).
