+         [contrib/suse/openssh.spec] Update spec file versions to 4.1p1
+ - (dtucker) [auth-pam.c] Since people don't seem to be getting the message
+   that USE_POSIX_THREADS is unsupported, not recommended and generally a bad
+   idea, it is now known as UNSUPPORTED_POSIX_THREADS_HACK.  Attempting to use

+20050503
+ - (dtucker) [canohost.c] normalise socket addresses returned by
