Hi, I'm having a slight problem building the c++ demos with gcc-3.3. (I had to
do a tiny patch against a few files to overcome the fact that multiline strings
are now not supported). But when it comes to building the c++ demos, I get the
following stuff:

make[1]: *** [c++.dc1] Error 1
</snip>
Does anyone know what this linker error actually means?

| (...) You should add -fno-rtti -fno-exceptions to the CXXFLAGS in Makefile.common. To get rid of the operator new/delete errors you can replace lib/c++/stub.c with a stub.cpp containing the following. Don't forget to update the Makefile. This works (...)
