Please direct questions regarding cygwin packages to the cygwin list, thx.

Info-ZIP zip-3.0 (available for both cygwin-1.5 and cygwin-1.7) supports
creating ZIP64 archives, AFAIK.

Info-ZIP unzip-6.0 (available only for cygwin-1.7) supports unpacking
(and listing) ZIP64 archives. For cygwin-1.5, only unzip-5.52 is
available, which doesn't support ZIP64.  You'll have to compile
unzip-6.0 on that platform yourself (and I don't know how difficult that
will be; there are a number of patches needed for clean builds on
cygwin-1.7, so I assume building on cygwin-1.5 will require similar
accommodation).

I do not plan to release unzip-6.0 for cygwin-1.5.
