Hi,

lately doesn't appear to accomplish much. Tested x86_64-linux.

Thanks,
Paolo.

	* cp-tree.h (finish_stmt): Do not declare.
	* decl.c (finish_stmt): Do not define.
	* parser.c (cp_parser_expression_statement,
	cp_parser_declaration_statement,
	cp_parser_transaction_cancel): Don't call finish_stmt.
	* semantics.c (finish_expr_stmt, finish_if_stmt,
	finish_while_stmt, finish_do_stmt, finish_return_stmt,
	finish_for_stmt, finish_switch_stmt, finish_compound_stmt,
	finish_transaction_stmt): Likewise.
