I suppose that you tried to compile the demo programs directly. This builds
a graphics sub-system that hasn't a single valid display driver, which may
explain why you don't get any display buffer..

Try compiling the file "graph/grinit.c" with the macro DEVICE_WIN32 defined.
This should "register" the Win32 driver in "graph/win32/grwin32.c"..
(and yes, this is done automatically by the build system from the command
line..)
