This puzzled me for a while too.  The trouble is that, despite the fact that
gcc is a C++ as well as a c compiler, it only comes with c libraries.  If
you want to use the C++ capabilities you need to obtain and compile the
g++ libraries.  The latest version is libg++-2.2.tar.Z  which can be
obtained from "all good ftp sites" (well, the GNU ones at least :-),
e.g. archie.au (plaza.aarnet.edu.au) in the /gnu directory.

This is unfortunately not made clear anywhere in the manual (at least, not
anywhere that I found).
