Go development environment on Windows with MSYS2

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.
