Now that renameat_noreplace works on DOS_NT, would it make sense to apply the attached further patch as well? If we can get renameat_noreplace to work on Cygwin the we could simplify the fileio.c code even further.

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.
