[gentoo-user] gcc4.7.2-r1 to 4.7.3 upgrade - hosed system?

[Adam Carter]

My system no longer had a /lib64/libgcc_s.so.1 which made it quite unhappy.
I eventually copied one over from a fedora live iso i had and things are
operational again. Is there some way i can confirm if it was the gcc
upgrade?

This looks damning;
