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.

	* ctypeid is actually has CTypeID type.
	* CTypeId is defined somewhere inside luajit's internal headers
	* which should not be included in init.h header.

This file has been truncated, but you can view the full file.

	~/go/src/github.com/cockroachdb/cockroach (master) $ git checkout beta-20170112
	Note: checking out 'beta-20170112'.

	You are in 'detached HEAD' state. You can look around, make experimental
	changes and commit them, and you can discard any commits you make in this
	state without impacting any branches by performing another checkout.

	If you want to create a new branch to retain commits you create, you may
	do so (now or later) by using -b with the checkout command again. Example:
