re PR c++/3478 (Accepts invalid "enum typename") 

PR c++/3478
	* parser.c (cp_parser_decl_specifier_seq): If the first decl_spec
	is error_mark_node, don't add any more decl_specs.
	(cp_parser_init_declarator): After committing to a declaration, if
	the decl_specifiers start with error_mark_node, issue an error and
	change the type to "int".
