Mingw-w64 is a collection of header files, import libraries, libraries and tools that, when combined with a compiler toolchain, such as GCC or LLVM, provides a complete development environment for building native Windows applications and libraries.

Standalone mingw-w64+GCC builds for Windows, built from scratch (including all dependencies) natively on Windows for Windows. Downloads are archive files (.zip or .7z).
