Right.  But I think we can make C++ pretty-printer a subclass of C's.
That will handle most of concerns you outlined later in your message.

As a concrete start, let's say we have

    typedef struct
       output_buffer buffer;
       tree scope;                    /* mostly a DECL_CONTEXT  */
       pp_formating_flags_t flags;    /* this one may be better passed
                                         as an explicit argument.  */
      void *x_data;                   /* front-end specific data.  */
    } pretty_printing_info;
Then use language hooks to print specific declarations and such; but
factor out commonalities.  I hope to be able to send a preliminary
patch (based on Jason's) late this night.

I'm not sure we want to go that far before the two front-ends got
