I will make the code I am working on portable across Solaris, Linux, Cygwin and native Windows. I just wanted to proove to my lab that cygwin is a very good product, but if you start from nearly scratch and want to run mostly only on Windows, doing native Windows is the best choice or writing portable code is the best.
