I'm in the process of writing an implementation of something like 
'renameat2', which I'll submit to the Cygwin developers.  Even if it's 
accepted, however, I think we'll still need to retain the 
case-insensitivity test for users of old versions of Cygwin, unless 
there's a decision to remove that because of the security concerns 
currently being discussed.
