Details:

Quoted from http://www.gnu.org/philosophy/gif.html:

We were able to search the patent databases of the USA, Canada, Japan, and
the European Union. The Unisys patent expired on 20 June 2003 in the USA, in
Europe it expired on 18 June 2004, in Japan patent expired on 20 June 2004
and in Canada it expired on 7 July 2004. The U.S. IBM patent expires 11
August 2006, (we are still searching the databases of other countries).

...and I don't think it's still necessary to restrict gif files, because it
seems to have expired for years.
