I don't use Windows myself, but I have recently built FlightGear from CVS 
under cygwin on someone else's machine (also Nvidia and VIA).

The process was reasonably straightforward, with a little help from Norman and 
Vivian on the IRC channel.

I used gcc-3.3.3 IIRC, although I'm sure Vivian is using 3.4 successfully.  
The main holdup was OpenAL - in the end, I used a precompiled version from 
Norman Vine (link was posted to the fg-devel list some time ago - 
http://www.vso.cape.com/~nhv/files/cygwin/cyg_openAL.tgz) which worked fine.

I believe the docs are out of date there - I spent ages trying to get rid of X 
unsuccessfully, only to be told it didn't matter.

I'm pretty sure I was using whatever glut is default with cygwin (IIRC, 
freeglut didn't work).

I actually tried updating and building today's CVS just to check, and confirm 
that it builds and runs fine on cygwin.  The only snag was in the "utils" 
directory, MIDG-II.cxx IIRC.

FG itself built and runs fine, I just removed the utils subdirectory from the 
makefile.

Hope that is of some use to you for now - if you need more assistance, I'm 
sure one of our more knowledgeable Cygwin users will be able to help.
