I'm not certain, but prior to GCC-4.8.0 I'd think it unlikely that you
could do that, simply because everything was written in C thereby
necessitating any C support that g++ would require.
Whether or not one can, following the 'rewrite in a subset of C++' in
4.8.0, now do --enable-languages=c++ on GCC's configure line and get a
working C++ compiler sans C support 'baggage' is an interesting
question. I might give it a try some time.
