     2  The generated libtool for building libstdc++ adds the -nostdlib option to the

     3  g++ command for linking but doesn't add -lgcc.  This causes a "hidden symbol"

     4  error when linking against the libstdc++ shared object.  This patch adds gcc

     5  to the list of libraries linked against when linking libstdc++.
