[GAP Forum] XGAP and cygwin

[Josef Lauri]

Thanks Alexander. I tried it and it works. But now I have decided to 
install Linux (kubuntu) and only use windows if I really need it under a 
virtual machine. Everything is now working much better for me. But for 
anyone who needs to remain with windows and run GAP I can recommend 
cygwin. Even though you do get a message like "unix binaries not 
installed" or "some functions which need Unix will not run", like those 
parts of GRAPE which use nauty, they actually do run!
