Hi @timonvo,

I have tested your patch.  It can't be compiled with `clang` because several types and defines are missing from `<clang>/lib/Headers/unwind.h`.  Thus, submitting this patch will break all self-bootstrapping build.

Please add following symbols to `<clang>/lib/Headers/unwind.h` in an independent commit beforehand:
