Solution:
-----------
include the following macro in the the Winnt.h before the following lines

typedef void *PVOID;
typedef void *POINTER_64 PVOID64;

After code change:
#define POINTER_64 __ptr64
typedef void *PVOID;
typedef void *POINTER_64 PVOID64;

AnotherSolution:
====================
Update BaseTsd.h with latest platform SDk file.
