Re: running 4.4 libstdc++ testsuite using 4.5's libstdc++ shared library

But, I do think we should make that clear by changing the SONAME when we

have the experimental stuff out there in a way that people can use it
*and* change its ABI *and* not adjust the SONAME.

Is there a way to identify "experimental" stuff? E.g. would it be possible to have a warning triggered by an option -Wlibstdcxx-experimental?
