  32         from ada-lex.l to here, where it is logically more appropriate.

  34         lookups for selector names in record aggregates.

  36         NAME for all of these.

  44         Rename some non-terminals to be closer to reference manual usage.

  48         (write_var_from_name): Remove.
  49         (write_var_or_type): New function, containing previous code from
  50         defunct write_var_from_name and name_lookup.
  51         (block_lookup): New function, moved from ada-lex.l
  52         (select_possible_type_sym): New function, factored out of
  53         name_lookup, which used to be in ada-lex.l.
  54         (find_primitive_type): Ditto.
  55         (chop_selector): Ditto.
  56         (write_ambiguous_var): New function, factored out of defunct
  57         write_var_from_name.
  58         (write_selectors): New function.

  67         (rules): Handle string escapes in processString.
  68         Add 'others' token.
  69         Return all NAMEs, BLOCKNAMEs, OBJECT_RENAMINGs, TYPENAMEs in
  70         yylval.sval (as simple strings).
  71         All name look-ups now handled in ada-exp.y.
  72         Introduce "::" (COLONCOLON) token and return as separate token.
  73         (processId): Change return convention.  Comment.
  74         Leave leading "'" in place.
