There is an installation or packaging problem of some kind.  It's
impossible to say what's going on without more details, but it looks
like this version of gcc was built by a third party vendor of Ada tools
who may have just omitted those parts of the compiler from the package,
or put them in an optional package that you don't have installed, or
maybe they never intended for C++ to work and included the g++ driver by
accident, or who knows.  You'd have to ask them.  Point is, this has got
something to do with how this particular gcc was packaged, not any
general absence of libstdc++ in this or any version of FSF gcc >= 3.

No, there's no add-on.  libstdc++ has been part of gcc for at least six
years and every release since 2.95 includes it.  The library is
installed whenever the C++ language is enabled in --enable-langauges;
and note that c++ is a default language so absense of any
--enable-languages should still build and install it.
