I know that there are some small ABI changes between libstdc++ 3.1 and
3.2.  This got mentioned in discussion of a PR that I filed concerning
the library under hpux.  Under hpux, all applications that were linked
against the 3.0 library needed to be relinked when the 3.0.1 library
was installed :-(

I still haven't figured out why libstdc++ needs to be installed prior
to running the testsuite.
