Additional efforts of the european branch of the NTPSB have uncovered
that the collision was due to low visibility across the atlantic.
And I wanted to go on:
All measures have been taken to limit the effects of the crash to a
minimum and to resume normal aircraft operation as soon as possible.
All crew members and passengers are required to apply following patch
to xntp3.3y.tar.Z for increased comfort and safety. This patch should
enable us to resume normal operation again.
After applying the patches you may remove following debris:
include/ntp_machine.h.rej
xntpd/ntp_config.c.rej
xntpd/ntp_control.c.rej
Unfortunately I did a test compile and the results of that will
extend the ground stay of the 3.3y aircraft considerably.
(You may start thinking about bringing up 3.3xx - see below)
SunOS 4.x.x does NOT have the new highly portable "memmove()"
routine. The lack of this will mean that we will have to
#define memmove(a, b, c) memcpy(a, b, c)
or find something else. I'd like to leave this to Paul.
Also on Sunos 4.x there are implicit declarations of bzero due
the the FDSET macro from the system header files. So I am not
so sure whether strictly using mem* is the best or whether we should
add b* prototypes to l_stdlib.h. I think Paul has now something
to work on. Anyhow, the patches below will rectify some problems
but the resulting code still needs much polishing (providing memmove
where it is missing e.g. SunOS4.x).
In order to get a flying version fast (3.3xx) Dave could apply my
patch he is holding to 3.3x - that should then make a workable
version. 3.3y can then be cleaned up slowly (starting with the
patches below and then port it again to the rest of the systems).
Sorry about the bad news.

That one is still to be applied because without it, it is possible
to shoot down any plane around the NTP universe that is bearing
the 3.3x banner (but can be applied to 3.3x).
For the 3.3y construction crew:
