[PATCH 07/12] mingw: only enable the MSYS2-specific stuff when compiling in MSYS2

Message-ID: <b00d242621ad2da67cd07edf34d3c8d3bb19f638.1785939999.git.gitgitgadget@gmail.com>
In-Reply-To: <pull.2195.git.1785939999.gitgitgadget@gmail.com>

From: Johannes Schindelin <johannes.schindelin@gmx.de>

The tell-tale is the presence of the `MSYSTEM` value while compiling, of course. In that case, we want to ensure that `MSYSTEM` is set when running `git.exe`, and also enable the magic MSYS2 tty detection.
