    libstdc++: Fix test that fails for C++98
    
    Local classes have no linkage so cannot be used as template arguments in
    C++98.
    
    libstdc++-v3/ChangeLog:
    
            * testsuite/20_util/specialized_algorithms/uninitialized_fill_n/sizes.cc:
            Move struct to namespace scope.
