Minimalist GNU win32 (cross) compiler (transition package)

 MinGW-w64 provides a development and runtime environment for 32- and
 64-bit (x86 and x64) Windows applications using the Windows API and
 the GNU Compiler Collection (gcc).
 .
 This transition package replaces the old MinGW-based C and C++
 compilers and allows building software using the old i586-mingw32msvc
 triplet.
