gnatbind -C appears to be used when bootstrapping gcc to generate .c files. With --enable-build-with-cxx, those .c files will be compiled with a C++ compiler. The symbols emitted by that compilation need to be linkable with the symbols emitted when compiling Ada code, so the .c files need extern "C" to avoid C++ mangling. Or at least so it seems to me. I may be missing some key step. Ian
