A quick request. Fransik, can you just post the literal contents of your zonecodes file? That always just seems to be way more reliable than the 'patch' system, and given the extent of your (really excellent) work, not really much longer. Patch is good for five or six changes; if you do a hundred, just give us the whole source file, we can figure out what we need. Otherwise, were stuck with going line-by-line through the patch and manually implementing everthing.

(by the way... i tried the patch and got the same hunk errors with a fresh copy of thne 5.13.10.5 tarball.)
