Let me try to clear things up:

-       POSIX ACLs are not a standard but a Standard proposal that
        has been modelled after an old UNIX ACL implementation from
        the early 1990s.

        The POSIX ACL proposal has been withdrawn around 1997.

-       The current ACL standard is in the NFSv4 spec (RFC-3530,
        http://www.ietf.org/rfc/rfc3530.txt) and is 100% bitwise
        identical to NTFS ACLs.

-       "tar" supports the UNIX ACL implementation since ~ 1995
        and NFSv4 ACLs since 2004.
        See: 
        http://src.opensolaris.org/source/xref/onnv/onnv-gate/usr/src/cmd/tar/
        This development for this source started ~ 1977

-       "star" supports the UNIX ACLs as well as the POSIX proposal
        since summer 2001.
        See: ftp://ftp.berlios.de/pub/star/alpha/
        This development for this source started ~ 1982

-       "GNU tar" does not support ACLs
        This development for this source started ~ 1986

-       Some other OS did start to support the withdrawn POSIX ACL
        proposal since 2002 (after star supported it).

-       star will support standard (NFSv4) ACLs soon.

What are you interested in?

If you need the old ACLs for one of the supported platforms (Solaris,
FreeBSD, Linux, SCO and probably IRIX and True-64), I recommend to use star.
