各プラットフォームで対応の準備が整ったので、C++ 言語の標準バージョンを C++20 にする。 なお、Visual Studio 用プロジェクトの設定は latest （C++23 の機能を含むプレビュー バージョン）が指定されていたが、こちらも C++20 を指定することとする。
C++20 では volatile は deplecated 扱いであり、configure の実行中に volatile を含むコードで警告が発生する。CI のコンパイルテストで -Werror を指定しているため、 警告がエラー扱いとなり configure がエラー終了してしまい、その結果テストが通らなくなる。 対策として autoconf 用マクロのコードから volatile を削除する。
C++20 では volatile は deprecated なので削除する。
