--- Comment #3 from Jonathan Wakely <redi at gcc dot gnu.org> ---
gcc/cp/typeck.c does:

      if (cxx_dialect >= cxx11)
        pedwarn (loc, OPT_Wwrite_strings,
                 "ISO C++ forbids converting a string constant to %qT",
                 totype);
      else
        warning_at (loc, OPT_Wwrite_strings,
                    "deprecated conversion from string constant to %qT",
                    totype);

As the example above shows, allowing the conversion and then conditionally
warning about it is not conforming.
