        * fold-const.c (native_encode_string): New function.
        (native_encode_expr): Use it for STRING_CST.

        * trans-const.c (gfc_conv_constant_to_tree): Warn when
        converting an integer outside of LOGICAL's range to
        LOGICAL.
        * trans-intrinsic.c (gfc_conv_intrinsic_function,
        gfc_conv_intrinsic_array_transfer, gfc_conv_intrinsic_transfer):
        Use INTEGER_TYPE instead of BOOLEAN_TYPE for TRANSFER as
        argument of another TRANSFER.

        * gfortran.dg/hollerith.f90: Don't assume a 32-bit value
        stored into logical variable will be preserved.
        * gfortran.dg/transfer_simplify_4.f90: Remove undefined
        cases.  Run at all optimization levels.  Add a couple of
        new tests.
        * gfortran.dg/hollerith5.f90: New test.
        * gfortran.dg/hollerith_legacy.f90: Add dg-warning.
