Which Autoconf version was the configure script created with?

No, sorry; these classes are unfortunately not portable enough yet.  The
configure script already sets LANGUAGE and LC_ALL to sane values.  If
that is not sufficient, then I suppose we need to set LANG, too.  What
system does this happen on, which sed version, and why does it not honor
LC_ALL=C?

Thanks,
Ralf
