    libstdc++: Correct statement about default -std option
    
    The default is -std=gnu++17 now, not -std=gnu++14.
    
    libstdc++-v3/ChangeLog:
    
            * doc/xml/manual/test.xml: Fix default for -std option.
            * doc/html/manual/test.html: Regenerate.
    
    (cherry picked from commit b93e60e7901526d7df2d8c0f5e0e46c57e8e3771)

       Since GCC 14, the libstdc++ testsuite has built-in support for running
