Some important changes were performed : 

- the graphics drivers were moved from "demos/config/*" to
  "demos/graph/*"

- a Win32 graphics driver was added. (note that keyboard
  management is a bit buggy, but it's really usable).

- the "demos/Makefile" and "demos/graph/rules.mk" were
  seriously modified

- the demo programs now compile AND run with gcc,
  Visual C++ and LCC-Win32 !! The other ones should be
  really easy to add now, as LCC was the really smart ass
  in this list...
