求助一处编译错误

In file included from /usr/include/linux/sched.h:14,
from /home/meng/ppp.c:23:
/usr/include/linux/timex.h:173: field `time' has incomplete type

如上，这是那里的问题
我的好几个程序都有这个问题

该程序只有下面４行
#include <linux/types.h>
#include <linux/fs.h>
#include <linux/mm.h>
#include <linux/errno.h>
#include <asm/segment.h>
却还报错，错误如下：

是不是编译需要什么参数的问题？
我的linux系统是新装的，应该不会是内核库文件坏了吧？
各位高手帮我
