Only in docs.

Don't define that in C++ code, since that requires int32_t, which isn't 
always present. It also requires #include <limits> and "using namespace 

Also note that you don't need to define INT32_MAX to a call to 
numeric_limit::max. For 32 bits exactly, MAX is (2^31)-1 and MIN 
is -(2^31).

So I feel this #define is unnecessary.
