Hello Harlan,

I'll attach a text that summarized my experience with the latest 
source. Summary: Everything is getting better....

Harlan,

I have some (bad) news for you. Here are my results of compiling
xntp3-5.89.1 on "i586-pc-linux-gnu":

There are a few Emacs backup files in the ``html'' directory. Maybe
leave them out from the distribution.

The problem reported previously (for 3-5.88) that some flags in
config.h are not set correctly is still there, but I know more about
it: If you re-run ./configure with different reference clocks enabled
(remember that all parse clocks are off by default), some flags are
not set correctly because they are cached. An example would be
``RAWDCF_SETDTR'' that is set correctly if you specify
``--enable-RAWDCF'' on the very first configure, but fails if you
re-configure with that option.

Ok, before I begin with compilation messages, I have an other little
note: For Windows/NT the file ``wininstall/setup.rul'' contains the
wrong version number (3-5.88). That might cause confusion if ever
used. Possibly the correct version number should be "configured in". I
don't run NT...

	gcc -c -DHAVE_CONFIG_H -I. -I. -I.. -I../include  -Wall -O2 -pipe refclock_parse.c
	refclock_parse.c: In function `rawdcf_init':
	refclock_parse.c:4217: warning: implicit declaration of function `ioctl'

I thought there was already a patch for that (#include <sys/ioctl.h>).
This little thing depends on ``RAWDCF_SETDTR''.

	gcc -c -DHAVE_CONFIG_H -I. -I. -I.. -I../include  -Wall -O2 -pipe ntptime.c
	ntptime.c: In function `main':
	ntptime.c:177: warning: implicit declaration of function `syscall'

Relevant parts from the configure session seem to be:
	...
	checking if declaring 'syscall()' is ok... yes
	...
	checking if we have a losing syscall()... no
	...

Finally a little runtime problem (stupid me!): If a non-root user
starts xntpd, you get a strange syslog:

Feb  3 21:28:36 elf xntpd[10209]: bind() fd 4, family 2, port 123, addr 00000000, in_classd=0 flags=1 fails: Permission denied

Finally, in xntpdc the help on ``keytype'' has an extra `key':
	xntpdc> he keytype
	function: set key type to use for authenticated requests (des|md5)
	usage: keytype [ key type (md5|des) ]
	xntpdc>keytype 15 des
	keytype must be 'md5' or 'des'
	xntpdc> keytype des
	xntpdc>
