Well, take the ISC license (works everywhere where they ratified the Berne convention) and remove most of of the warranties and you have a EU license. Most of the EU countries lack laws about merchantability and fitness for a particular purpose, or at least lacks the need to be explicit about it (either because a "software provided "as is" without any warranties" will be enough to disclaim all warranties, or because you can't disclaim some warranties). Just make sure it works in your jurisdiction. Any international questions will, iirc, be governed by whatever the UN deal is called which is a bit more lax about implied warranties that UCC in the US.

But it is a minefield anyway, so just use the ISC license.
