  The code in question dates back to when "long" was the longest

  universal then).

Today, intmax_t is the longest integer type.  Perhaps most of the longs
in zic.t should be changed to intmax_t.

Does Microsoft's MSVC (which is a C89 compiler) have support for
intmax_t (and <stdint.h> or <inttypes.h>)?  Does the TZ code have to
work with Microsoft compilers?

The latest version supports <stdint.h>, but NOT inttypes.h or
printf("%jd" [etc]). I am unsure whether it supports long long (the
headers are still full of __int64), but it does support %lld.

I don't know what version these features were added in.
