    Go development environment on Windows with MSYS2

Normally, it is sufficient to grab the Go MSI installer from the website in
order to set up the toolchain. However, some packages that provide Go wrappers
for C libraries rely on cgo tool, which in turn,
needs the GCC toolchain in order to build the glue code. Also, 3rd-party
dependencies are usually hosted on services like GitHub, thus
Git is also needed. This mini-guide illustrates how to
setup a convenient development environment on Windows using MSYS2.
