re PR c/20385 (Lame parse error message for undefined type)
gcc:

PR c/20385
* function.c (used_types_insert): Handle ERROR_MARK.
* c-decl.c (grokdeclarator): Handle ERROR_MARK.
(declspecs_add_type): Leave error_mark_node in specs->type.
(finish_declspecs): Change it to integer_type_node here.
* c-parser.c (c_parser_peek_2nd_token): Move earlier.
(enum c_lookahead_kind): New.
(c_parser_next_token_starts_typename): New name of
c_parser_next_tokens_start_typename. Accept lookahead enum
and handle it here instead of...
(c_parser_next_tokens_start_declaration): ... here. Call it.
(c_parser_declspecs): Accept another argument. Do not exit
on C_ID_ID if it is guessed to be an unknown typename.
(c_parser_parms_declarator): Use 2nd token to distinguish a K&R
declaration from an ANSI declaration starting with an unknown
typename.
(c_parser_struct_declaration, c_parser_objc_type_name,
c_parser_typeof_specifier, c_parser_declarator,
c_parser_direct_declarator_inner): Adjust calls.
(c_parser_parameter_declaration): Likewise.
(c_parser_type_name): Pass back an error_mark_node to the caller.
(c_parser_postfix_expression): Do error recovery when
c_parser_type_name returns NULL.
