Re: libstdc++ baseline updates for 3.4/HEAD

There are no up-to-date baselines on the branch: what's in CVS are the
old 3.2.x baselines. The difference between those baselines, and the
actual symbols in 3.4.0 are expected and unsurprising.

You need to use the 3.4.0 release sources, not something from the branch.

Please do not check in, regardless of previous approval, until I ok the patch.

I'm not quite sure what is up with this. I've configured exactly as you
have, and have my same symbols, exactly.

Let's start here. This should be weak in io-inst.o. 

What I'd like you to do is start with 3.4.0 sources, no patches, default
configure. Try to reproduce my results. Then, once that's done, try to
figure out what is different between 3.4.0 release and your sources. I
don't expect divergence in libstdc++ sources, so maybe this is
compiler-related? Or, if there are libstdc++ differences, what are they?
