Committed the 1.2.10 changes on Jan 13.  1.2.11 was released a few days ago.
Updating the trunk with the new version, checked with a build without using a
system zlib.

NightStrike proposed to revert to the 1.2.8 release until zlib stabilizes again;
I'm open for that, but didn't want to stay with the 1.2.10 release.
