--- Comment #4 from Paul Sanders <p.sanders at alpinesoft dot co.uk> ---
Sorry, that didn't happen on purpose.  I edited the title, maybe that's what
caused it, or maybe it's because someone (Martin?) changed the component from
gcc to libstdc++.

Anyway, I won't post anything further here (I probably shouldn't have posted
that last one, but saying 'GIGO' is not a valid reason for ignoring this
issue).
