zip and unzip from Info-ZIP version update

[paul.hermeneutic@gmail.com]

It would seem that Cygwin is using a somewhat old version of Info-ZIP
from which zip and unzip are created.  The info-zip.org


>From the http://info-zip.org/ site, there is:

"""
All known vulnerabilities are fixed in Zip 2.32.
"""

However, it appears that Cygwin is using version 3.0.

What is the process to get this updated?  Please advise.  Thanks.
