testsuite/20_util/specialized_algorithms/pstl/uninitialized_copy_move.cc:
            Replace references to namespace __pstl with std.
            * testsuite/25_algorithms/pstl/alg_merge/inplace_merge.cc:
            Likewise.
            * testsuite/25_algorithms/pstl/alg_modifying_operations/copy_if.cc:
            Likewise.
            * 
testsuite/25_algorithms/pstl/alg_modifying_operations/copy_move.cc:
            Likewise.
            * 
testsuite/25_algorithms/pstl/alg_modifying_operations/is_partitioned.cc:
            Likewise.
            * 
testsuite/25_algorithms/pstl/alg_modifying_operations/partition.cc:
            Likewise.
            * 
testsuite/25_algorithms/pstl/alg_modifying_operations/partition_copy.cc:
            Likewise.
            * testsuite/25_algorithms/pstl/alg_modifying_operations/remove.cc:
            Likewise.
            * testsuite/25_algorithms/pstl/alg_modifying_operations/rotate.cc:

            * testsuite/25_algorithms/pstl/alg_modifying_operations/unique.cc:
            Likewise.
            * 
testsuite/25_algorithms/pstl/alg_modifying_operations/unique_copy_equal.cc:
