Let me be more clear.

1. Freestanding C++ in the current situation is very problematic. (You do not
have memcpy, you do not have std::move. You do not have std::forward. You do
not have std::addressof(). you do not have std::array.) However, you have an
exception handling support.

2. What's the point of reporting a bug when building libstdc++ with GNU newlib
just works much better and you have an entire hosted toolchain that will not
break compilation? The only problem is that you never enable EH.
I did report bugs before. However, it was not fixed. I am not going to try it
again tbh since newlib works just fine.
