Is that a concern? The GNU strings [1] are translated and even their untranslated text does differ from that of the BSD ones [2]. The set of errors is also different, e.g. REG_EMPTY is only in BSD because its regcomp() does not accept `()' while GNU's does. But it's precisely this difference that I think would help clue users into why their scripts work on one platform and not another.
