Synopsis
********

     AX_ZONEINFO([options...])

Description
***********

This macro finds compiled zoneinfo files.  If successful it will define HAVE_ZONEINFO per:

       AC_DEFINE([HAVE_ZONEINFO], [1], [...])

and have the variable TZDIR point to the zoneinfo directory as per

       AC_SUBST([TZDIR])
       AC_DEFINE_UNQUOTED([TZDIR], [/path/to/zic/files], [...])

Optionally, OPTIONS can be `right' to trigger further tests that will determine if leap second fix-ups are available.  If so the variables HAVE_ZONEINFO_RIGHT, ZONEINFO_UTC_RIGHT and TZDIR_RIGHT will be populated:

       AC_DEFINE([HAVE_ZONEINFO_RIGHT], [1], [...])
       AC_SUBST([TZDIR_RIGHT])
       AC_DEFINE_UNQUOTED([TZDIR_RIGHT], [/path/to/right/zic/files], [...])
       AC_SUBST([ZONEINFO_UTC_RIGHT])
       AC_DEFINE_UNQUOTED([ZONEINFO_UTC_RIGHT], [$ZONEINFO_UTC_RIGHT], [...])
