50分新人小疑点

50分新人小问题求助！
#include <iostream.h>
#define LPSTR char*
#define UINT unsigned int
#define PASCAL _stdcall
class CObject;
struct CRuntimeClass
{
LPSTR m_lpszClassName;
int m_nObjectSize;
UINT m_wSchema;
CObject* (PASCAL*m_pfnCreateObject)();   //这个后面也暂时用不到  不知道这个PASCAL是什么类型。这个函数暂时不知道什么意思。
CRuntimeClass* m_pBaseClass;
static CRuntimeClass* pFirstClass;
CRuntimeClass* m_pNextClass;
};
struct AFX_CLASSINIT{
AFX_CLASSINIT(CRuntimeClass*pNewClass);
};
#define RUNTIME_CLASS(class_name)\
(&class_name::class##class_name)

#define DECLAER_DYNAMIC(class_name) \
public:\
static CRuntimeClass class##class_name\
virtual CRuntimeClass* GetRuntimeClass() const;

#define _IMPLEMENT_RUNTIMECLASS(class_name,base_class_name,wSchema,pfnNew)\
    static char _lpsz##class_name[]=#class_name; \
CRuntimeClass class_name::class##class_name={ \
_lpsz##class_name，sizeof(class_name),wSchema,pfnNew, \
RUNTIME_CLASS(base_class_name),NULL};

#define IMPLEMENT_DYNAMIC(class_name,base_class_name)\
   _IMPLEMENT_RUNTIMECLASS(class_name,base_class_name,0xFFFF,NULL)

  这段代码是我在仿真MFC 类别型录网所写的代码，其中imlement_runtimeclass还没有写完但是已经出现了下面的错误：
g:\tdr编程\vc++学习练习\mfc real\mfc.h(30) : error C2653: 'class_name' : is not a class or namespace name
g:\tdr编程\vc++学习练习\mfc real\mfc.h(30) : error C2589: 'class' : illegal token on right side of '::'
g:\tdr编程\vc++学习练习\mfc real\mfc.h(30) : error C2143: syntax error : missing ';' before '::'
g:\tdr编程\vc++学习练习\mfc real\mfc.h(30) : error C2143: syntax error : missing ';' before '::'
g:\tdr编程\vc++学习练习\mfc real\mfc.h(30) : error C2014: preprocessor command must start as first nonwhite space
   问题就在我标记红色的那一栏请问到底怎么解决谢谢了！
