I'm not surprised that plugins don't work
For Milepost we need both the --enable-build-with-cxx configure option and plugins. How is this supposed to work? Should the person compiling the plugins use C++ to compile the plugin? Or should the cc1 / cc1plus dso export unambiguous symbols with C linkage names in addition to the C++ linkage names? Or should we have a language extension to specify C++ linkage in C headers, and arrange for the gcc headers that are installed for teh benefit of plugins to reflect the used build/bootstrap language so that either gcc or g++ will just work, using references with the appropriate names?
