Using Cygwin
Several days ago, I downloaded Cygwin, which is a collection of tools, library, and API that provide Unix-like functionality on Windows platform. Installation is quite easy, we only need to download a small setup file, then run it to further select and download packages we need.
Using Cygwin, we can develop and build applications normally written for POSIX operating system, and run them on Windows from Cygwin shell. This is possible because Cygwin provides DLL that complements Win32 API with additional POSIX-like API, which is called Cygwin API.
I personally use Cygwin to run ProFTPD, because there’s a need for testing my program with Unix-based FTP server. I could have used linux, but I was just too lazy to install linux on my office PC
