Subject: cp-tree.h (enum_name_string): Remove prototype.

	* cp-tree.h (enum_name_string): Remove prototype.
	(report_case_error): Remove prototype.
	* cp/typeck2.c (enum_name_string): Remove.
	(report_case_error): Remove.
	* error.c (dump_expr): Deal with enum values directly.
	Correctly negate integer constant.
