------- Additional Comments From peterreilly@apache.org  2005-01-11 19:32 -------
Ok, I have found a "NEWS" entry for tar:
http://savannah.gnu.org/cgi-bin/viewcvs/tar/tar/NEWS?rev=1.83&content-type=text/vnd.viewcvs-markup
the relavent section is:
version 1.13.9 - Paul Eggert, 1999-08-18.

* `tar' now writes two zero blocks at end-of-archive instead of just one.
  POSIX.1 requires this, and some other `tar' implementations check for it.


So it looks like it is a good idea to output two zero blocks.
As a zero block is used to finish an archive, there should
be no BC problems with having two.

I have committed the change to ant cvs and ant cvs 1.6 branch, it
should be in the next release of ant.
Thanks for the patch.
