`lsd` reports an error ("os error 1336"). But that might simply 
be a result of the "non canonical order".

As I wrote, it's a "fresh Cygwin installation on a test 
system" that means the phenomennon is observable directly after 
the installation.

I did some testing: files created in the user's home directory 
(/home/Administrator), the home directory (/home) and other sub 
directories don't show the issue.

If I create a file or directory directly under / or anywhere 
else on the drive, the issue occurs.

If that would be the case on my main workstation, I would be 
fine with that. Unfortunately on my main workstation the issue 
occurs everywhere.
