Hi Victor,

I rebased and simplified this, and added a lot of tests to be able to
understand what it does. I think all systems that didn't have this
are now EOL and we don't need to support them in PG16, but perhaps our
_WIN32_WINNT is not quite high enough (this requires Win10 RS1, which
itself was EOL'd in 2019); the main question I have now is what
happens when you run this on non-NTFS filesystems, and whether we want
to *require* this to work because the non-POSIX support will probably
finish up untested. I posted all that over on a new thread where I am
tidying up lots of related stuff, and I didn't want to repost the
proposed testing framework in multiple threads...
