Automating GHC build for Windows

[Gintautas Miliauskas]

Hi Páli,

that error is reminiscent of issues when trying to move a file that is open
(and implicitly locked) by another process. I have seen some sporadic
issues like that in the build unfortunately (never tracked them down to the
root cause though), Maybe it's something silly like one process not having
enough time to clean up and close the file before the next command tries to
move it? I'd add a sleep before the mv and see if that helps. Does the
build proceed if you try "make" without cleaning the repository, or does it
hang again at the same spot?
