[Bug-tar] gtar's ACL support is still unusable

[Joerg Schilling]

Hi,

I recently mentioned that gtar typically does not support ACLs at all. It e.g. 
does not compile the provided ACL code on any POSIX certified platform.

Now I discovered another problem:

I recently compiled gtar-1.31 on Linux and did some testing. While doing so, I 
discovered that gtar does not unpack any of the ACL reference archives 
correctly.

Trying to unpack the reference archives for the POSIX ACL proposal from 1993
that was withdrawn in 1997 results in something like:

/tmp/tar-1.31/src/tar --acls -xpf acl-test3.tar.gz     
/tmp/tar-1.31/src/tar: default/dir2: Warnung: Funktion acl_from_text 
fehlgeschlagen
/tmp/tar-1.31/src/tar: default/dir3: Warnung: Funktion acl_from_text 
fehlgeschlagen
/tmp/tar-1.31/src/tar: default: Warnung: Funktion acl_from_text fehlgeschlagen
/tmp/tar-1.31/src/tar: default: Warnung: Funktion acl_from_text fehlgeschlagen

If you extract the archive using "star" and then try to create a tar archive 
with ACL support using "gtar", you get an archive that is non-compliant to the 
format definition:

The reference archives are here:

They are also included in the latest schilytools tarball at:
