It actually looks like a bug, translating into C escape strings twice:

The first time is in parse-gram.y, in the rule
string_as_id:
  STRING
    {
      $$ = symbol_get (quotearg_style (c_quoting_style, $1), @1);
      symbol_class_set ($$, token_sym, @1, false);
    }
;

The second time is, as noted before, in 'prepare_symbols', output.c, the lines
    set_quoting_style (qo, c_quoting_style);
    set_quoting_flags (qo, QA_SPLIT_TRIGRAPHS);

Both are needed: removing any, will cause the .cc code to not compile due to 
some symbols. Also, trigraphs are removed from C++17.
