Ok that's what I thought. I'll do this too.

Aaah. This is the part I cannot figure out. I don't have to do it
immediately, but I'd feel better if, at the very least, I could check
the exported symbols on 3.2 against the 3.2.0 release so I know that at
least the symbols stayed the same.

Right now I'm doing:

nm --extern-only --portability libstdc++.so.5.0.0 | awk '{ print $1 $2}'
>& symbols.txt

sort symbols.txt >& symbols_sorted.txt

For 3.2, 3.3, and diffing the bits.
