Tar'ing up a windows dir (ProgData) had some unexected failures:

Several of the sort:

tar: Dbgview: Warning: Cannot llistxattrat: No such file or directory
tar: Desktops: Warning: Cannot llistxattrat: No such file or directory
tar: DiskView: Warning: Cannot llistxattrat: No such file or directory
tar: LoadOrd: Warning: Cannot llistxattrat: No such file or directory
tar: portmon: Warning: Cannot llistxattrat: No such file or directory

Where the item listed (Dbgview, DiskView, etc) is a
windows symlink like:

2019/02/07  22:53    <SYMLINK>      Dbgview [SI\Dbgview.exe]
2019/02/07  22:53    <SYMLINK>      Desktops [SI\Desktops.exe]
2019/02/07  22:53    <SYMLINK>      DiskView [SI\DiskView.exe]

and stems from the use of the --xattrs switch.

Win7SP1x64
cygcheck (cygwin) 3.2.0

The tar continued and finished much as it would after an unreadable file.

Another error, maybe similar,


tar: C\:Prog64FastPictureViewer: Warning: Cannot file_has_acl_at: No 
such file or directory

 From a file in "C:\Program Files\FastPictureViewer" [likely mis-]named
"C:Prog64FastPictureViewer"

It seems to be a .dll, that somehow got its name mangled.

Not sure what it was trying to do, but the file seems to be 'in-use'.
