* 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.
