(get_scope): For IPv4 scope, use scopes table. (fini): Free scopes table if necessary. (free_scopelist): New function. (scopecmp): New function. (gaiconf_init): Also handle scopev4 entries. * posix/tst-rfc3484.c (do_test): Initialize scopes. * posix/tst-rfc3484-2.c (do_test): Likewise. * posix/gai.conf: Document scopev4 defaults. * posix/Makefile (tests): Add tst-rfc3484-3. * posix/tst-rfc3484-3.c: New file.
