Note that we have libstdc++/13631, about messages. It would be nice if 
you could comment on that audit trail thus saving the additional details 
in a convenient place.

Constructively, I would also encourage you to submit fixes, preferably 
of a sort not breaking the binary compatibility (otherwise, we can still 
look into the patches now, but would be targeted at the ABI breaking 
branch opened by Francois)

Thanks,
Paolo.
