mingw-w64-x86_64 8.0.0 Minimalist GNU for Windows
Minimalist GNU for Windows (MinGW) is a complete software development environment for creating native Microsoft Windows applications.
It includes a set of Windows-specific header files and static import libraries which enable the use of the Windows API. It does not rely on any third-party C runtime dynamic-link libraries (DLLs).
Mingw-w64 is an advancement of the original mingw.org project and provides several new APIs such as DirectX and DDK, and 64-bit support.
