I think that the situation is that when linking with the C++ compiler,
the C++ compiler automatically adds linkage to its own libstdc++.so.
Libtool also adds linkage to libstdc++.so (as a dependency) so the
linker sees the (hopefully) same shared library listed twice.  There
would be a severe problem if libtool was to request linking with a
different libstdc++.so than the C++ compiler needs.

Solaris ld warns about this issue, and presumably GNU ld does not.
