Hi Uthpal,

Are you allowed to modify the application file? It is generally a bad idea
to #define identifiers, that can likely be used in other header files.

So, the preferred solution is to modify that application header. Instead of:
#define uint64_t unsigned __int64
typedef unsigned __int64 uint64_t;

Or better yet, just use #include <stdint.h> or <cstdint> if they are
available, because they provide the typedef uint64_t and alike.

On the other hand, if you are not allowed to modify the offending
application file, then you'll need some trickery to work around this. I can
elaborate on this if you need it.
