in soldoni uno potrebbe dire che cygnwin e' un emulatore, ma:

- Cygwin is not a way to run native linux apps on Windows. You have to rebuild your application from source if you want it to run on Windows.
- Cygwin is not a way to magically make native Windows apps aware of UNIX ® functionality, like signals, ptys, etc. Again, you need to build your apps from source if you want to take advantage of Cygwin functionality.

quindi non emula nel senso stetto del termine (non esegue binari), fornisce invece emulazione delle API, quindi devi ricompilare.

- A DLL (cygwin1.dll) which acts as a Linux API emulation layer providing substantial Linux API functionality.
- A collection of tools which provide Linux look and feel.
