Log message:
	* c-common.h (add_stmt): Change prototype.
	(RECHAIN_STMTS): New macro.
	(CASE_LABEL_DECL): Likewise.
	(genrtl_case_label): Change prototype.
	(c_expand_start_case): Remove prototype.
	(build_case_label): Change prototype.
	(decl_constant_value): Declare.
	* c-common.c (check_case_value): Handle C++'s extensions to C
	semantics.
	* c-commnon.def (CASE_LABEL): Add room for the CASE_LABEL_DECL
	field.
	* c-parse.in (stmt): Adjust handling of return statements and case
	laels.
	* c-semantics.c (add_stmt): Return the new statement.
	(genrtl_return_stmt): Take the RETURN_STMT as input, not the
	returned expression.  Directly generate RTL, rather than calling
	c_expand_return.
	(genrtl_switch_stmt): Don't call c_expand_start_case.
	(build_case_label): Take the LABEL_DECL as input, too.
	(genrtl_case_label): Just call add_case_node.
	(expand_stmt): Adjust calls to genrtl_return_stmt and
	genrtl_case_label.
	* c-tree.h (c_expand_start_case): Declare.
	* c-typeck.c (decl_constant_value): Give it external linkage.
	(c_expand_return): Don't call expand_return or expand_null_return;
	use genrtl_return_stmt instead.
	* stmt.c (struct nesting): Remove num_ranges field.
	(add_case_node): Give it external linkage.
	(expand_start_case): Don't set num_ranges.
	(expand_start_case_dummy): Don't clear it.
	(pushcase): Rely on add_case_node to handle `default' labels.
	(add_case_node): Handle `default' labels.
	* tree.c (tree_int_cst_compare): New function.
	* tree.h (tree_int_cst_compare): Declare.
	(add_case_node): Likewise.
	
	* cp-tree.h (push_switch): Change prototype.
	(check_cp_case_value): Remove declaration.
	(decl_constant_value): Likewise.
	* decl.c (struct cp_switch): Add switch_stmt and cases.
	(case_compare): New function.
	(push_switch): Set switch_stmt.  Initialize cases.
	(pop_switch): Clean up cases.
	(define_case_label): Rename to ...
	(finish_case_label): ... this.  Do semantic analysis for case
	labels here.
	(start_function): Correct comment.
	* decl2.c (check_cp_case_value): Remove.
	* expr.c (do_case): Remove.
	* pt.c (tsubst_expr): Adjust call to finish_case_label.
	* semantics.c (genrtl_do_poplevel): Remove declaration.
	(RECHAIN_STMTS): Remove.
	(finish_break_stmt): Use build_break_stmt.
	(finish_continue_stmt): Use build_continue_stmt.
	(finish_switch_cond): Adjust condition here, rater than in
	c_expand_start_case.
	(finish_case_label): Remove.
	* typeck.c (c_expand_return): Remove.
	(c_expand_start_case): Likewise.
