	* objc-act.c (objc_eh_runtime_type): Avoid ICE if error_mark_node
	is passed as argument.
	(objc_begin_catch_clause): Added code to deal with an
	error_mark_node or NULL_TREE argument.  Improved checks for
	invalid arguments.  Added code to traverse typedefs.

	* parser.c (cp_parser_objc_try_catch_finally_statement): Parse
	@catch(...)  and pass NULL_TREE to objc_begin_catch_clause() in
	that case.  Improved error recovery.  Reorganized code to be
	almost identical to c_parser_objc_try_catch_finally_statement.

	* c-parser.c (c_parser_objc_try_catch_statement): Renamed to
	c_parser_objc_try_catch_finally_statement for consistency with the
	C++ parser.  Parse @catch(...) and pass NULL_TREE to
	objc_begin_catch_clause() in that case.  Improved error recovery.
	Reorganized code to be almost identical to
	cp_parser_objc_try_catch_finally_statement.
