The MinGW-w64 (MinGW fork) project is a complete runtime environment for gcc to produce binaries native to Windows 64-bit and 32-bit operating systems.

Mingw-w64 delivers runtime, headers and libs for developing both 64 bit (x64) and 32 bit (x86) windows applications using GCC and other free software compilers.

Features:

  • Compiler toolchain hosts natively
  • Supports Native TLS Callbacks
  • Supports Wide-Character Startup (-municode)
  • Supports 32-bit and 64-bit Windows i386/x64
  • Supports Multilib toolchains
  • Supports bleeding edge gcc/binutils

Official Website: http://mingw-w64.sourceforge.net/index.php
