    libstdc++: Apply r13-1096-g6abe341558abec change to vstring too [PR101482]

    As recently done for std::basic_string, __gnu_cxx::__versa_string
    equality comparisons can check lengths first for any character type and
    traits type, not only for std::char_traits<char>.

    libstdc++-v3/ChangeLog:

            PR libstdc++/101482
            * include/ext/vstring.h (operator==): Always check lengths
            before comparing.
