   > I see that `# define UNUSED(a) ((void)(1 || (a)))`, so why this change is needed?
   
   UNUSED is frequently redefined by many third party to something like this:
   ```
   # define UNUSED __attribute__((unused))
   ```
   Since assert(assert.h) is the most used macro, it's better to remove the dependence on UNUSED macro.
