Summary: Portability issue: os.rename behaves differently on win32

Initial Comment:
os.rename(src, dst) fails on Windows if dst already exist and regular file. On Unixes, it does not fail, and silently overwrites dst. It's better to use MoveFileEx(src, dst, MOVEFILE_REPLACE_EXISTING) when moving regular files under Win32 to make it behave consistent way.

This change would be an incompatible change; see the discussion of the
proposed patch. Closing this report as "won't fix".

>From MSDN document and googling, it does look like
MOVEFILE_REPLACE_EXISTING guarantees atomicity for rename operation. I will
see if I can come up with a patch (I will first need to learn building
python on windows).
