Parts of the GNU toolchain are also directly used with or ported to other platforms such as Solaris, Mac OS X, Microsoft Windows (via Cygwin and MinGW/MSYS) and Sony PlayStation 3.
Microsoft Windows is not shipped with support for X, but many third-party implementations exist, as free and open source software such as Cygwin/X, and proprietary products such as Exceed, MKS X/Server, Reflection X, X-Win32 and Xming.
