* intl/dcigettext.c (DCIGETTEXT): If _nl_find_msg returns -1 don't
look further, return original strings. (_nl_find_msg): Do not return found translation if the conversion failed. Either signal the string is unusable or that something went wrong and the original should be used. 2006-06-21 Ulrich Drepper <drepper@redhat.com> * string/_strerror.c (__strerror_r): Add __builtin_expect.
