I think this patch is great,  although I haven't had time to test it yet.  The
only real "backend change" is the exception-handling clause;  and the fact
that the backend will also be linked against the C++ runtime library.
Everything else is routine stuff that an experienced C++ developer would end
up catching while trying to get his build-system for a new project running;
but it could certainly scare away someone with less experience.  Better to
deal with this way ahead of time and test it on a few platforms.
