Maybe it is the right thing to do, but what is your take of why it must be so (all the way) ?

I also do understand that it have several advantages in the implementation of std::filesystem but it also imply an extra layer of abstraction to the underlaying platform, but to just remove the _CYGWIN_ macro when building it would make std::filesystem to not understand /cygdrive at all (and I guess that would confuse other users;-) so I guess it would require some more sophisticated implementation (or extend the number of exceptions already existing in the underlaying Cygwin-Posix-implementation)

Best regards,
