The C++ standard library is based on a particular revision of the C standard (e.g., C++23 is based on C17, C++17 is based on C11, C++14 is based on C99). The compiler provides some of the C standard library headers, but it exposes non-conforming interfaces from them in some language modes. For example:
https://godbolt.org/z/G8W7Gs1vE
https://godbolt.org/z/vbjs787TT
https://godbolt.org/z/Ks67KEoh3
For improved conformance, we should do a comprehensive review of the C standard library headers provided by Clang to ensure that we're exposing the proper interfaces in the proper language modes.
