This usually means that your header search paths are not configured properly. \
The header search paths should contain the C++ Standard Library headers before \
any C Standard Library, and you are probably using compiler flags that make that \
not be the case.

// deprecated in libc++ in https://github.com/llvm/llvm-project/pull/80542.
// Based on the post commit feedback the macro are no longer deprecated.
