Hi, Sergey!
Thanks for the patch!
LGTM, with a minor comment below.

Minor: I suggest to wrapping this into the `#ifndef`, since the
`UNUSED()` is a very common macro. The same one is used in the LuaJIT.
For now these macros are the same [1] but to avoid rewriting code in the
case of the changes, it is better to use `#ifndef` directive here.
