Sorry to be blunt, but the circumstances don't matter.  If you want
Cygwin (and thus: tar) to behave better, I need a reproducer.  For that
I must be able to create a DACL which looks like yours so I see the same
"Invalid argument" message.

So, again, please provide the cacls or icacls command creating a
directory that allows to reproduce the issue.

If that's not possible, you will have to debug this yourself, ideally by
running tar under GDB and setting a breakpoint to Cygwin's acl_to_text
function to find out what it chokes on.
