    libstdc++: Fix brainwrong in path::_S_convert(T) [PR102743]

    This function was supposed to check whether the parameter's value type
    is the same as path::value_type, and therefore needs no conversion.
    Instead it checks whether the parameter is the same as its own value
    type, which is never true. This means we incorrectly return a string
    view for the case where T is path::string_type, instead of just
    returning the string itself. The only place that happens is
    path::_S_convert_loc for Windows, where we call _S_convert with a
    std::wstring rvalue.

    This fixes the condition in _S_convert(T).

    libstdc++-v3/ChangeLog:

            PR libstdc++/102743
            * include/bits/fs_path.h (path::_S_convert(T)): Fix condition
            for returning the same string unchanged.
