C
程序
MinGW
也为
Windows
提供
GCC
编译器，但不同于
Gygwin
，
GCC
的
MinGW
版本生成
32
位
Windows
程序，而不需要特别的运行库。它的变体版本
MinGW-w64
，也称为
MinGW64
，能生成
64
位程序。可以通过网址
http://sourceforge.net/projects/mingw
或
http://sourceforge.net/projects/mingw-w64
获取安装程序，安装最新版本的
MinGW
。
注意，
Cygwin
包管理器也允许安装
MinGW-GCC
包。
GCC
因此具备类似交互编译器的能

Cygwin
上运行，但是生成不使用

网站上列举了由第三方针对各种不同系统制作的
GCC
安装包，可以通过访问网址
