Hi!
When localedef -f X -i Y Y doesn't create /usr/lib/locale/Y,
one cannot see it in subsequent locale -a output.
The following patch fixes that.
2002-12-13 Jakub Jelinek <jakub@redhat.com>
* locale/programs/locale.c: 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.
