definitions for CAObjHandle: stdtst.h, userint.h & cviauto.h

When building application in 64-bits with CVI 2013, I've an error about CAObjHandle that in several files:

userint.h:typedef intptr_t    CAObjHandle;
cviauto.h: typedef intptr_t         CAObjHandle;    

stdtst: typedef int    CAObjHandle;    

first files are from CVI (C:\Program Files (x86)\National Instruments\CVI2013\include) and second from teststand (C:\Users\Public\Documents\National Instruments\TestStand 2013\AdapterSupport\CVI): I make a DLL with CVI and then call its functions from a seqauence in teststand.

If I compile in 32-bits, there is not such an error as types have then the same size...

What can be done to solve that?
