* inet/getnameinfo.c (getnameinfo): For AF_INET, check errnocvs/fedora-glibc-20060828T1903
only if herrno is NETDB_INTERNAL. Handle errors other than ERANGE outside of the loops, handle TRY_AGAIN. * locale/programs/ld-ctype.c (translit_flatten): Issue error if other's ctype category was missing. * locale/programs/ld-collate.c (collate_read): Return if copy_locale's collate category is missing.
