Re: [tz] zic option to generate smaller output files?

I think you need to be able to generate files in which (a) the 32-bit data isn't there,*and* (b) the TZ string actually controls results for current timestamps in some popular zones.

Yes, (b) is part of my proposal. Sorry I wasn't clear. Because the tzfile format is independent of the current time and date, (b) follows the format's rules and should work -- though you're right, some client-code bugs may be exposed by (b). (a), on the other hand, is not clearly contemplated by tzfile(5), and may well break non-buggy code in 32-bit clients that never look at the 64-bit data. So it requires a change to the tzfile format and is a bigger deal.
