Speaking of gcc-4.2.1, Ted Jordan writes on 20090401:
The generated libtool for building libstdc++ adds the -nostdlib option to the
g++ command for linking but doesn't add -lgcc. This causes a "hidden symbol"
error when linking against the libstdc++ shared object. This patch adds gcc
to the list of libraries linked against when linking libstdc++.
