  56         (write_var_from_name): Remove.

  58         defunct write_var_from_name and name_lookup.
  59         (block_lookup): New function, moved from ada-lex.l
  60         (select_possible_type_sym): New function, factored out of
  61         name_lookup, which used to be in ada-lex.l.

  63         (chop_selector): Ditto.
  64         (write_ambiguous_var): New function, factored out of defunct
  65         write_var_from_name.

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