Harlan,

maybe you can remember yesterday's message about platform-specific port
initialization. Yesterday I debugged why ATOM won't work with Linux.

I found out that ntp_refclock.c contains a lot of specific stuff that does
not work correctly. For example there's a SYS_SOLARIS and a STREAM symbol
there that config.h does not know about. The file should be cleaned up.

For the meantime I added a one-liner in refclock_atom that will do it for
Linux (and maybe others too). Look for "Linux" in the patch.

I also included a patch from Frank kardel that fixes a buffer overflow in
the parse driver (I had reported several times). I use this patch with
3-5.90.2 for several weeks now and the overflow is gone. Frank wanted to
send you the patch, too, but maybe he was too busy...

Yesterday I reported anotherminor problem to Frank, but look at the output
first:

rkdvmhp1:windl(29) %  ntpq -c cl

ILLEGAL TIME: 00:01:04 (0.00%); running time: 34d+14:31:13"

All fields except the first are separated by a comma, and the values are
enclosed by double-quotes if it's a string. I wrote a CGI script to
monitor xntpd, and thus I recognized the inconsistency...

Regards,
Ulrich
P.S: Hope your mailer survives...
