[GRASS5] cygwin/windows port

Hi Andreas.

There are still autoconfig problems

- Needs to choose "bison -y" instead of "yacc".

- Doesn't find openGL libraries.

Yes!

Is there a fifo implementation yet?  My understanding is that none of this
will work without it.

As you say, Cygwin has Windows API headers.  I'm not sure what the driver
would need that you would need MSVC++ for.  There is also the mingw compiler
(gcc without Cygwin).

If the fifo problem is not an issue, please tell me what to do to make a
driver, and I will think about building one.  I am unsure of how much time I
will have over the next two months, but I can at least work out what is
required.
