I am removing these from the source code in preparation for an
upcoming 1.9.18alpha release. We can't release with this code in there as it currently stands as it might breach ITAR export restrictions in the US. I've discussed ways around this with Jeremy and we can put the code back in with appropriate modifications once it is needed. Note that this code isn't actually used in Samba yet, so removing it has no effect. If anyone wants the code then look in ~samba-bugs/arcfour/ or grab it from the CVS attic. (This used to be commit 426cd6b2ded4725186a9262f13a327d8cf94364b)
