zic and zoneinfo.zip

[Ravindra]

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
