Could there be a "Version 4" of the compiled TZif files in which the ints and time_ts have the correct endianness for the platform on which they're installed?

I imagine a zic command-line argument that selects:

- always big-endian (the default for compatibility),

- always little-endian, or

- the correct endianness for the platform on which zic is running.

This wouldn't let users rip out all their endianness code since not all TZif files would be version 4; but it might reduce running time in programs that read lots of TZif files.

Does this make sense, or is it just premature optimization?
