问什么执行Think\Think::start();会出这个错误，怎么处理？
Warning: Unexpected character in input: '\' (ASCII=92) state=0 in E:\AppServ\www\zlg\ThinkPHP\ThinkPHP\ThinkPHP.php on line 94

Parse error: syntax error, unexpected T_STRING in E:\AppServ\www\zlg\ThinkPHP\ThinkPHP\ThinkPHP.php on line 94

这个代码是Think.class.php中未修改过的
