Where did you find (so quickly) that MoveFileEx is not atomic on Windows? If you're including Windows 95 (and 98 and ME) in your list of things, then yes, there rename is (in a weirdly surprising way) not implemented as atomic operation, but I doubt the prudence of supporting Windows 9x when even Perl does not really care about it anymore (but I can't find the p5p email stating that "no contortions for supporting Win9x will be made", so that may be wishful thinking here).

Update: Building on Win9x is unsupported

Update: Windows 95 Chainsaw Massacre - it seems that some code in 5.12 survived this, but that's to be expected of a maintenance release. At least 5.14 won't support Windows 9x anymore.
