huh?

I mean... "This doesn't mean we would need to use any more C++ features
like classes or templates"
The next step is to mark everything extern C, and make sure it's all
mangled before it hits codegen (that happens anyways).  ABI
compatibility is preserved.  We win.

The only problem I see with this plan is that LLVM supposedly HAS a C
backend, but I've yet to hear about any C++ backend.  It may be a lot
more work than if you can just use some macro/setjmp/etc hacks to make
eh work in C.
