The Msys DTK contains a bison and flex that are adequate for our
purposes. Are you sure you installed the developer tools?

I just followed this recipe. However, I had to do the following
additional small steps on a fresh Windows Server 2012 instances on Amazon:

* the git installer had to be run as Administrator or it got
permissions violations
* I had to add this to the end of the MSys PATH: ":/c/prog/git/cmd" (I
installed it in c:/prog/git)
* I had to add "C:/mingw /mingw" to the fstab

Given that, I was able to clone the code, build it and run the
regression set without incident. This was using the gcc that comes with
the mingw installer, not the separate one from mingw-w64.

Not to my knowledge. Perhaps the tarball generator should create a file
reporting the head commit on the branch.
