Summary: Directory.renameFile broken under windows

Initial Comment:

According to the library report, renameFile should succed 
even if the target file already exists. Under windows it 
fails with:
 
Fail: already exists
Action: renameFile
Reason: File exists
File: foo

(ghc 6.0 and 6.0.1)

The reason seems to be that it uses the rename library 
call directly, which indeed fails if the target exists:

url=/library/en-
us/vclib/html/_crt_rename.2c_._wrename.asp

A solution might involve MoveFileEx(old, new, 
MOVEFILE_REPLACE_EXISTING) ?
