How is this different from the following?

  inline const char *get_nostatic() { return "foo"; }

or

  inline const char *get_separate() {
    const char *temp = "foo";
    static const char *str = tmp;
    return str;
  }

Please find or add something in the standard which will allow us to
not export a symbol for every string literal(*) that happens to be used
in a function with weak linkage.
