If the current approach is to patch libc++ from the outside, then yeah, that's most definitely not a great design IMO. It's going to be very brittle. I think it *may* be reasonable to support this in libc++, but I'd like to see some sort of basic explanation of what the changes would be so we can have a discussion and make our mind up about whether we can support this, and what's the best way of doing it.
