  62         defunct write_var_from_name and name_lookup.
  63         (block_lookup): New function, moved from ada-lex.l
  64         (select_possible_type_sym): New function, factored out of
  65         name_lookup, which used to be in ada-lex.l.

  67         (chop_selector): Ditto.
  68         (write_ambiguous_var): New function, factored out of defunct
  69         write_var_from_name.

  79         (rules): Handle string escapes in processString.
  80         Add 'others' token.
  81         Return all NAMEs, BLOCKNAMEs, OBJECT_RENAMINGs, TYPENAMEs in
  82         yylval.sval (as simple strings).
  83         All name look-ups now handled in ada-exp.y.
  84         Introduce "::" (COLONCOLON) token and return as separate token.
  85         (processId): Change return convention.  Comment.
  86         Leave leading "'" in place.
