Thank you! This fixes it for the Cygwin side, although the symlinks are still 
technically not right from the Windows side. They're still showing up prefixed 
\??\.

It's an age since I mucked around with those functions - IIRC the API function 
for writing them adds the \??\ itself and doesn't expect it to have been 
supplied? However, when you read the reparse point you have to remember to 
remove it yourself because who needs consistency :o)

C:\cygwin64>dir /s | findstr ??
01/06/2022  04:30 PM    <SYMLINK>      cert.pem 
[\??\C:\cygwin64\etc\pki\ca-trust\extracted\pem\tls-ca-bundle.pem]
01/06/2022  04:30 PM    <SYMLINK>      ca-bundle.crt 
[\??\C:\cygwin64\etc\pki\ca-trust\extracted\pem\tls-ca-bundle.pem]

All best,
