You cannot include GNU GPL v2.0 or later code in a The Unlicense-licensed project and ship the result under The Unlicense. GNU GPL v2.0 or later requires the combined work to be distributed under GNU GPL v2.0 or later (or compatible). If your project is meant to stay The Unlicense-only, do not include GNU GPL v2.0 or later code in it.

GNU GPL v2.0 or later: GPL-2.0 with explicit upgrade path; users may pick GPL-2.0 or any later GPL.
The Unlicense: Public-domain dedication with a fallback license for jurisdictions that don't recognise PD.
