+     install a C++ runtime library.  Just as GNU C does not distribute
+     a C runtime library, it also does not include a C++ runtime
+     library.  All I/O functionality, special class libraries, etc., are
+     provided by the C++ runtime library.
+
+     Here's one way to build and install a C++ runtime library for GNU
+     CC:
+
+        * Build and install GNU CC, so that invoking `gcc' obtains the
+          GNU CC that was just built.
+
+        * Obtain a copy of a compatible `libstdc++' distribution.  For
+          example, the `libstdc++-2.8.0.tar.gz' distribution should be
+          compatible with GCC 2.8.0.  GCC distributors normally
+          distribute `libstdc++' as well.
+
+        * Set the `CXX' environment variable to `gcc' while running the
+          `libstdc++' distribution's `configure' command.  Use the same
+          `configure' options that you used when you invoked GCC's
+          `configure' command.
+
+        * Invoke `make' to build the C++ runtime.
+
+        * Invoke `make install' to install the C++ runtime.
+
+     To summarize, after building and installing GNU CC, invoke the
+     following shell commands in the topmost directory of the C++
+     library distribution.  For CONFIGURE-OPTIONS, use the same options
+     that you used to configure GNU CC.
+
+          $ CXX=gcc ./configure CONFIGURE-OPTIONS
+          $ make
+          $ make install
