AX_ZONEINFO([options...])
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], [...])
