Ah, I see. I'm a little hesitant about such an environment, because code built with each exception handling model is essentially a different ABI, and having them all in the same setup feels pretty prone to errors. Like, you need to have built your libcxx and libcxxabi with matching exception handling models as well, so then you need three copies of them as well.
