Git for Windows 1.x was retired on August 18th, 2015, superseded by Git for Windows 2.x. The development environment of Git for Windows 2.x is no longer maintained in a monolithic Git repository but rather as the Git SDK, a friendly fork of MSys2 pre-configured to ease the development of Git for Windows.
This is the build environment -- also known as msysGit -- for Git for Windows.
msysGit brings a few components that are required to build Git:
cd /git && git ls-files \*.shfor a full list).
cd /git && git ls-files \*.perl), most notably
Git for Windows is the software package that installs a minimal environment to run Git on Windows. It comes with a Bash (a Unix-type shell), with a Perl interpreter and with the Git executable and its dependencies.
On the other hand, msysGit is the software package installing the build environment that can build Git for Windows. The easiest way is to install it via the net installer.
The MinGW project's goal is to provide a way to compile native Windows binaries with no POSIX layer using the GNU C Compiler.
However, at least the Bash needs a POSIX layer (most notably due to the absence of the
fork() call on Windows). Therefore, MSys (the minimal system) is thrown in, offering the minimal system necessary to offer Bash (and Perl) functionality on Windows.
Consequently, MSys ships with a POSIX layer (based on an old version of Cygwin) that is only used by the Bash and Perl, but not by anything compiled within that environment.
