There was some mention of "Win 10 or later" in the thread, IIRC,
while explaining why Cygwin version of rename() works.  Is it
possible that the version of Windows and Cygwin you and Patrick
used are different enough?

In the meantime, I'll queue a SQUASH??? on top for preparing today's
integration.

This is a tangent, but there are places that use !MINGW,!CYGWIN and
there are places that use !WINDOWS; I think they are equivalent
prerequisites that we might want to straighten out their uses as a
clean-up later.
