[置頂]宏的問題

#if !defined(AFX_YOHU_H__A2E721BD_9454_4959_ABD4_8AB69FF99689__INCLUDED_)
#define AFX_YOHU_H__A2E721BD_9454_4959_ABD4_8AB69FF99689__INCLUDED_

#if _MSC_VER > 1000
#pragma once
#endif // _MSC_VER > 1000

#ifdef _DEBUG
#define new DEBUG_NEW
#undef THIS_FILE
static char THIS_FILE[] = __FILE__;
#endif


以上的宏,我不是很明白,請高手指點
