Fix file renaming in MinGW

Browse Source 
We now use MoveFileEx, which is not assured to be atomic but works for
always (both if the destination exists, or if it doesn't) and is
available in MinGW.

Since this is a Win32 API call, complaint about lost or overwritten files
should be forwarded at Steve Ballmer.
