FWIW, I took a look at this, but it's a pile of C++ operator overloads with circular dependencies which GCC seems to be perfectly fine with but clang complains about. I tried adding forward declarations but that didn't work; this is beyond my superficial knowledge of C++.

Upstream seems to be dead, there are forks around but none of them have a fix for this particular issue. Someone with better knowledge of C++ needs to take on this one if this is going to be fixed.
