Duplicate ACLs? - Can't copy file even with Admin permissions

[cygwin@kosowsky.org]

Hi Corinna,
I found another file with ACLs that fail even under the new snapshot
cygwin1.dll.

#getfacl setup.ilg
# file: setup.ilg
# owner: Administrators
# group: None
getfacl: setup.ilg: Invalid argument

#icacls.exe setup.ilg
setup.ilg NT SERVICE\TrustedInstaller:(I)(F)
          NT SERVICE\TrustedInstaller:(I)(CI)(IO)(F)
          NT AUTHORITY\SYSTEM:(I)(F)
          NT AUTHORITY\SYSTEM:(I)(OI)(CI)(IO)(F)
          BUILTIN\Administrators:(I)(F)
          BUILTIN\Administrators:(I)(OI)(CI)(IO)(F)
          BUILTIN\Users:(I)(RX)
          BUILTIN\Users:(I)(OI)(CI)(IO)(GR,GE)
          CREATOR OWNER:(I)(OI)(CI)(IO)(F)

#icacls.exe setup.ilg /save setup.acl
#cat setup.acl
setup.ilg
