New description:
The update to MacOS 11.3 and Xcode 12.5, with Command Line Tools, broke
clang++ 11: It can not find system headers such as wchar.h, it seems.
Unclear with workarounds. Curiously, g++ 10 works.
Specifically,
/opt/local/bin/clang++-mp-11 hello_world.cc -o hello_world
produces the errors below, whereas
/opt/local/bin/g++-mp-10 hello_world.cc -o hello_world
works.
