5 Cygwin...is it? a large collection of GNU and Open Source tools which provide functionality similar to a Linux distribution on Windows. a DLL (cygwin1.dll) which provides substantail POSIX API functionality.... isn t it? a way to run native Linux apps on Windows. You must rebuild your application from source if you want it to run on Windows. a way to magically make native Windows apps aware of UNIX R functionalty like signals, ptys, etc. Again, you need to build your apps form source if you want to take advantage of Cygwin functionality....form 5 / 39
