I've been trying to say over and over again that our code doesn't handle any Windows specific stuff and not anywhere have I claimed that anyone else need to handle Windows specific stuff either (except for the internals of Cygwin of which Windows specific logic is already present)

I repeat; I don't expect any of the Cygwin-Posix-functions to accept any Windows-style-paths (though some of them, as I repeatedly have said, already does so) and I only expect that I can operate according to the C++-standard on an instantiated std::filesystem::path

I repeat (again); neither MinGW/MSVS is an option because we're trying to use Posix and C++

Just to be clear:

- Our code DOESN'T handle Windows-style-paths explicitly in any way
- We DON'T expect Cygwin-Posix-file-related-functions to accept Windows-style-paths
- We WOULD like std::filesystem to work according to the C++ ISO standard


Does that make any sense ?
