zic and zoneinfo.zip

We use tzcode and tzdata in our app. We are adding support for 64-bit platforms (Windows and Linux) in our app. I would like to know the right way to generate zoneinfo.zip from tzdata2010l.tar.gz (using "zic -d" command). I have following doubts: 1. Is it ok to use same zoneinfo.zip for 32-bit as well as 64-bit platform? 2. Do I need to build two zic (32-bit and 64-bit) binaries in order to generate separate zoneinfo.zip files for 32-bit and 64-bit platforms? 3. If same zoneinfo.zip can be used for both the platforms, which zic should I use to generate the zoneinfo.zip (32-bit zic or 64-bit zic)? Could someone please clarify my doubts above? Thanks in advance, Ravindra
