This did not work ( changing config options ) but I looked at the output of configure for clues and noticed checks for libstdc++-static libs -- once I installed these the build succeeds and fails upon removal of the package. I also see that the cc1 binary built during bootstrap does not dynamically link to libstdc++ -- problem solved! Is this expected at all? Thanks for the help!
