I don't know how Cygwin implemented rename(), but if they used MoveFile() 
they broke the POSIX rename() since MoveFile() fails if destination 
already exists. They should have used MoveFileEx(MOVEFILE_REPLACE_EXISTING)
instead, to guarantee POSIX semantics. The symptoms you're experiencing 
make me think this might be the case (even if it is strange, since other 
Unix software would fail the same way).
