我写了这样一个头文件
#ifndef _filelist_H

#define _filelist_H

#include <iostream.h>

#include <list.h>

class filesetlist: class list;

{

public:

friend ostream & operator << ( ostream &, list &);

int flag;

double qidian_x;

double qidian_y;

double qidian_h;

double zhongdian_x;

double zhongdian_y;

double zhongdian_h;

double yuanxin_x;

double yuanxin_y;

double yuanxin_h;

double yuanxin_r;

double yuanxin_l;

};

#endif;

然后又写了这样的filelist.cpp文件

#include "list.h"

ostream & operator << ( ostream &out, list &li)

{
out<< li.qidian_x<< li.qidian_y<< li.qidian_h<<endl;

out<< li.zhongdian_x<< li.zhongdian_y<< li.zhongdian_h<<endl;

out<< li.yuanxin_x<< li.yuanxin_y<< li.yuanxin_h<< li.yuanxin_r<< li.yuanxin_l<<endl;

return out;
}

可是编译是时提示
error C2146: syntax error : missing ';' before identifier 'Length'
error C2501: 'DWORD' : missing storage-class or type specifiers
error C2501: 'Length' : missing storage-class or type specifiers
error C2146: syntax error : missing ';' before identifier 'GetPrevLink'
error C2433: 'WINAPI' : 'inline' not permitted on data declarations
fatal error C1004: unexpected end of file found

是什么原因啊？
