Running Cygwin setup 2.912 with --symlink-type native (or
CYGWIN=winsymlinks:native) is not correctly translating all symlinks.
A default install has these faulty ones:

\??\/etc\pki\ca-trust\extracted\pem\tls-ca-bundle.pem

Thanks for testing. It seems I still didn't have this quite right and
these symlinks just happened to work for cygwin, but not native tools.

I'm afraid that's just changed the \??\ to \\?\ on those symlinks.
Well, that has the advantage of being correct :)
(since it's the 'Win32 File Namespace' prefix, which
CreateSymbolicLinkW() is documented to accept for the target filename,
and is required when that exceeds MAX_PATH (260) characters)
In my (brief) testing, e.g. the CMD builtin 'type' is able to open
symlinks of this form. However, it seems there are some parts of
Windows (e.g. DIR, File Explorer), which don't handle symlinks like that
well.
So, I've copied the behaviour of the cygwin DLL, which avoids using that
prefix if the target is less than MAX_PATH characters. This seem to
work better in those cases with typical paths (but I'd claim we're just
working around a bug in Windows here, as things will still be broken if
the cygwin root is a path long enough that we can't do that).
