To disable inlining functions, you MUST
#define HANDMADE_MATH_NO_INLINE
in EXACTLY one C or C++ file that includes this header, BEFORE the
include, like this:
#define HANDMADE_MATH_IMPLEMENTATION
#define HANDMADE_MATH_CPP_MODE
#define HANDMADE_MATH_NO_INLINE
#include "HandmadeMath.h"
All other files should just #include "HandmadeMath.h" without the #define.
