Unable to compile IcedTea with CACAO under Fedora 17

I've updated it for the release branch as well, so for that, replace
the first three lines by:

$ hg clone http://icedtea.classpath.org/hg/release/icedtea7-2.3 icedtea7
$ cd icedtea7
$ hg up -c icedtea-2.3.3
$ hg pull -r icedtea-2.3 https://bitbucket.org/Ringdingcoder/icedtea7
