msys2

===================================

MSYS2 provides two versions of make, one in the make package and one in the mingw-w64-{i686,x86_64}-make packages. The latter one is called mingw32-make on command line, is fully native and doesn't depend on msys2 shells.

MSYS2 uses Pacman (known from Arch Linux) to manage its packages and comes with three different package repositories:

msys2: Containing MSYS2-dependent software

mingw64: Containing 64-bit native Windows software (compiled with mingw-w64 x86_64 toolchain)

mingw32: Containing 32-bit native Windows software (compiled with mingw-w64 i686 toolchain)

Cygwin comes only with Cygwin-dependent software. It uses its own package management system, commonly called setup.exe.

MSYS2

-----------------------

Cygwin provides a runtime library called cygwin1.dll that provides the POSIX compatibility layer where necessary. The MSYS2 variant of this library is called msys-2.0.dll
