It is a compile time decision. It can be propagated like this (in 
interface file) (copied a piece of cpl_port.h):

%include "../../port/cpl_config.h"
#if defined(WIN32) && defined(_MSC_VER)
typedef __int64          GIntBig;
typedef unsigned __int64 GUIntBig;
#elif HAVE_LONG_LONG
typedef long long        GIntBig;
typedef unsigned long long GUIntBig;
#else
typedef long             GIntBig;
typedef unsigned long    GUIntBig;
#endif
