This replaces the w32 patches in 4.2.4 that added the authreg directive. - bsc#962318: Call /usr/sbin/sntp with full path to synchronize in start-ntpd. When run as cron job, /usr/sbin/ is not in the path, which caused the synchronization to fail. - bsc#782060: Speedup ntpq. - bsc#916617: Add /var/db/ntp-kod. - bsc#956773: Add ntp-ENOBUFS.patch to limit a warning that might happen quite a lot on loaded systems. - bsc#951559,bsc#975496: Fix the TZ offset output of sntp during DST. - Add ntp-fork.patch and build with threads disabled to allow name resolution even when running chrooted.
