Include locarchive.h. (ARCHIVE_NAME): Define. (write_archive_locales): New function. (write_locales): Use it. Ensure the same locale is not printed multiple times in verbose mode. Mode LC_IDENTIFICATION and LC_CTYPE printing into... (print_LC_IDENTIFICATION, print_LC_CTYPE): ... these helper functions. (struct nameent): New type. (nameentcmp): New function.
