>Description:
here's a patch I wrote to partiall implement zipinfo (-Z) support for
the base unzip. This fixes some test failures seen with perl 5.12 and
5.14.
>How-To-Repeat:
install perl 5.12 or 5.14 on 9.x or 10.x and run "make test". Some
tests related to Archive::Extract will fail due to trying to call
unzip -Z -1 filename. This patch makes that work.
