编译出现的错误，郁闷！

编译程序时出现这样的错误，该怎么解决啊？
"c:program filesmicrosoft visual studiovc98mfcincludeafxver_.h(130) : fatal error C1189: #error : Please use the /MD switch for _AFXDLL builds"

// C1189.cpp
#undef _WIN32

#if !defined(_WIN32)
#error _WIN32 must be defined   // C1189
#endif

int main() {
   return 0;
}
You may also see this error if you build an ATL project with the /robust MIDL compiler option. /robust is only for use when building for a Windows 2000 or later machine. So, either remove /robust or change this line in the dlldatax.c file:
#define _WIN32_WINNT 0x0400   //for WinNT 4.0 or Win95 with DCOM
to
#define _WIN32_WINNT 0x0500   //for WinNT 4.0 or Win95 with DCOM
