The C++ Standard Library: clang++とg++でコンパイルしてみた(まとめ)
https://qiita.com/kaizen_nagoya/items/9bdfaa392443d13e5759

目的(purpose)

The C++ Standard Libraryコンパイル記録は、コンパイラおよび対応標準、コンパイラの版により、コンパイルエラーMessageの違いを記録し、どのエラーが出たら、どの版またはどの対応標準にすればエラーが少なくなるかを考察するための資料の第一歩です。

成果(outcome)

(1)コンパイラの種類、対応標準の違いによってエラーの数が違う。
(2)同じエラーであってもMessageの表現が違う。
(3) Error Messageのネットで検索する際に役立つ。
