Function prototype definition

The funciton is defined as:

LONG WINAPI InterlockedCompareExchange (
    __inout LONG volatile *Destination,
    __in    LONG Exchange,
    __in    LONG Comperand
    );

In Visual 6.0, I use it as:
      int nRet = (int)::InterlockedCompareExchange((PVOID*)pI, (PVOID)nNew, (PVOID)nOld);

Compiler has no complain.

In Visual 2005, Compiler complains as such:

1>d:\develop\3.0\commonlibs\base\asm.h(47) : error C2664: 'InterlockedCompareExchange' : cannot convert parameter 1 from 'PVOID *' to 'volatile LONG *'

What should I do?

Thanks,
