While working on an unrelated issue I noticed that the compiler didn't

I thought about limiting the permissiveness to only extern "C"
functions, but I believe that system headers are adding more C++
declarations, so we'd likely run into this issue again.
Shouldn't we build libstdc++ with -Wsystem-headers? Maybe along with
-Wno-error=system-headers?
It's been suggested before:
