FYI: A small bugfix was applied to the xetex sources today; it is now at version 0.999.4 (checked in as svn r.9980). The issue is a very minor one, so it is *not* essential that all the binaries are rebuilt just for this. However, if it's convenient to do so, or if they're being rebuilt for other reasons anyway, it'd be good to include this update. JK
