# XXX The global-tz distribution omits the zone1970.tab file, precluding

# tzsetup objects (fatally) if any entry in zone.tab or zone1970.tab
# refers to a country code that doesn't exist in misc/iso3166. While
# arguably that should be fixed, for compatibility we remove such
# entries here to avoid the problem.
#
# This used to be done by adding patch files for each country to
# remove, but that doesn't work for zone1970.tab.
#
# We generate a list of all 2-letter codes that are NOT in iso3166;
# then, for any entry in zone.tab or zone1970.tab that contains a bad
# code: first emit a commented-out version of the line, then a version
# with the bad codes stripped out of the first field (unless this
# leaves the first field empty).
