Problems with WaitableTimer

Hi all!
I have a problem with using WaitableTimers

VC60 doesn't want to compile it
even if i do like MSDN said:

#define _WIN32_WINNT 0x0500
#include <windows.h>
Maybe someone knows other ways to compile functions like
CreateWaitableTimer()
Answer me please...

p.s. My NT2000 build is 1251
