If I understand the code and its behaviour correct (which I asusme I did, but feel free to correct me, the relevant data is tzload() in lib/libc/stdtime/localtime.c :-), the version two data is added to the end of the zonefile. A diff of the two shows that this is indeed happening. I have installed the new zonefile on an 7.0 OS and ran the regression tests and old zdump on it without problems. So the conclusion for me is that it is working fine with statically linked libraries. For 7.0 users, the patches can be found at http://www.mavetju.org/~edwin/tzcode2008e-update-7.txt.
