I'm interested, too.

FWIW:
I gave up trying to track down the details, and went with the easy way out:
I installed the fc3 libstdc++.so.6 rpm and updated to the fc3 libgcc_s.so rpm.
(Now apt-get is unhappy that I have two libstdc++'s installed,
so I may have to repackage fc3's libstdc++ to keep it happy...)

One of these days I'd like to understand the details, but for now I seem
to be happy.
