This reverts commit 6262201182a0ee357d8a456e6d1a8e5984e4c6dd.
in 62622011, we wanted address the needs to use the string_view converter in C++98, but that requirement was based on wrong preconditions. std::string_view was introduced in C++17, and popular standard libraries like libstdc++ and libc++ both provide std::string_view when the source is built with C++17.
furthermore 62622011 is buggy. because it uses <version> to tell the feature set provided by the standard library. but <version> is a part of C++20. so this defeats the purpose of the change of 62622011.
