I don't think adding a new flag is such a good idea, especially since
it's setting is not independent of flag_cxx0x.

For better future-proofing, we should introduce an enum:

  enum cxx_dialect {
    cxx98,
    cxx0x
  };

and then replace flag_cxx0x with:

  enum cxx_dialect dialect;

Then, we can test "dialect != cxx98" and "dialect == cxx0x" as appropriate.
