That doesn't mean much.

You can write an ABI in C++ in such a way that -Bsymbolic will work
just fine. BTW, as for those C++ programs which don't work, they
don't conform to the ABI :-).
Remember we only have to deal with the shared libgcc when we want
better support for C++. The static libgcc is fine with C.
