 # 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).
