MinGW Introduction

MINGW (minimalist GNU on Windows) is an emulated Linux compilation environment that compiles Linux programs under Windows, and provides Linux C, C + + header files, system libraries, and a collection of compilation tools under Linux, such as GCC , g++, and make tools. Allows the compiled binary to run on Windows. (The previous Cygwin, though also a GNU Windows transplant, was Cygwin copyrighted, not GNU)
