f:\cyuyanyu\vc++英文版\[大家网]visual.c++.6.en[www.topsage.com]\vc98\include\winuser.h(39) : error C2146: syntax error : missing ';' before identifier 'HDWP'
f:\cyuyanyu\vc++英文版\[大家网]visual.c++.6.en[www.topsage.com]\vc98\include\winuser.h(39) : fatal error C1004: unexpected end of file found

下面是winuser.h中的一段代码
#include <stdarg.h>
#ifndef NOUSER

typedef HANDLE HDWP; (以上两个错误都指向这一行)
typedef VOID MENUTEMPLATEA;
typedef VOID MENUTEMPLATEW;
#ifdef UNICODE
typedef MENUTEMPLATEW MENUTEMPLATE;
#else
typedef MENUTEMPLATEA MENUTEMPLATE;
#endif // UNICODE
找不出原因,请大家帮帮忙
