早期freebsd实现

I recommend reading this ENTIRE FILE before you attempt to build BIND.

----- 4.9.2 BETA4 (931104) release - November, 1993 - paul @vix.com

All reported portability problems have been fixed.  All core dumps have
had changes made for them and we are ready to have them tested again.  As
usual, I am running this in production on my own zones and I am rather
confident in it.  Note, again, that this is a BETA release and you should
not put it up for anon-ftp or otherwise republish it in any way.

----- 4.9.2 ALPHA2 (930908) release - September, 1993 - [e-mail]

If you're looking for general information on BIND, the mailing list you want
is [e-mail]; you can ask to be added to this list by sending mail to
[e-mail].  (The person who maintains the list does not read
it, so posting your "please add me" notes to the main list will be ineffective
as well as rude.)

4.9.2 has fixes for most of the bugs that smb@bellcore's white paper talked
about, and CERT is going to be knocking on vendor's doors to get it shipped
with as many operating systems as possible.

----- 4.9.2 ALPHA1 (930506) release - July, 1993 - Paul Vixie <[e-mail]>

I don't work for DEC any more, so note the new e-mail address.  The old
<[e-mail]> list has been moved to <[e-mail]>; if
you intend to help hack BIND and you want to be advised of alpha-testing
releases, send mail to <[e-mail]> and ask to be added
to the list.

Note that 4.9.1 was an interrim, nonpublished release intended to catch
the porting changes needed for 4.4BSD.  It never really existed separately.

----- 4.9 release - April, 1993 - Paul Vixie <[e-mail]>

For information on what's new in 4.9, see OPTIONS and CHANGES.  Also note
that the man page for named(8) in man/named.8, and the entire Bind Operations
Guide in doc/BOG/*, has been updated for 4.9.  Both make excellent reading.

Those of you who are thinking of adding features should first read TODO to
see if someone else has already indicated an intention to work on the same
thing.  If your feature is significant you should ask <[e-mail]>
before you hack, if for no other reason than to tell other maintainers to
expect a patch soon.

Note that the resolver has a number of routines that may already be present
on your system.  Efforts have been made to avoid generating code for them on
systems where they aren't needed; don't worry about them if they're
generated unneccessarily since the linker will sort things out.

--Copyright--

To build this:

	(on SUNOS, use the BSD build environment or you will
	get the wrong definition for O_NDELAY)

	look at conf/options.h and edit to your tastes.
	The OPTIONS file here in this directory will help you
	figure out what to do.

	You should also look at the Makefile to select the proper set
	of definitions depending on whether you are using Ultrix,
	SunOS, and other 4.[23] BSD-alikes or using BSD 4.4, BSD/386,
	and other net2-alikes.

	"make links" will build a shadow source tree full
	of symbolic links.  the default name of this tree
	is "./native.b", but you can override it by setting
	the DST variable on the "make" command line, as in:
		make DST=vax.b SRC=..
	if your DST is not a subdir of "here", you will need to
	override the SRC variable's default (which is ".."),
	as in:
		make DST=/tmp/vax.b SRC=`pwd` 
	note that the DST directory must be nonexistent at
	the time that you run "make links".

	after "make links", you can cd to the new build
	directory to run "make depend".  if you aren't using
	"make links" (shame on you), just use "make depend"
	from "here".  "make depend" may fail on your system;
	if so, look in the bin/ directory and find a mkdep that
	does in fact work for you.

	if you skip the "make depend" phase, or after you run it,
	you can do "make all" (from the build directory if you
	used "make links" or from "here" if you're just hacking
	around).  you will get the following new things out of it:
		res/libresolv.a
		compat/lib/lib44bsd.a (optional)
		include/{netdb,resolv}.h
		include/arpa/{inet,nameser}.h
		compat/include/sys/{cdefs,bitypes}.h
		tools/{nstest,nsquery,dig,host}
		tools/nslookup/nslookup
		named/named
		named/named-xfer
	if you have trouble with "make all", check conf/portability.h
	for things that your system needs, or doesn't need, or whatever.
	it is preferable to add #ifdef's to conf/portability.h than to
	add them anywhere else.
	
	from the build directory (or "here" if you didn't
	use "make links"), you can try "make -n install"
	which will tell you what will be installed.  it might
	actually be right; however, what you will probably have to
	do is copy the above files into the places you want
	run them from.  the other files you will need are:
		tools/nslookup/nslookup.help
		named/named.restart
		named/named.reload

	resolver library notes: to install it, either put the .a
	file into /usr/local/lib or /usr/lib (if you use -lresolv
	on all the links of your networking software), or use "ar"
	to put all res/*.o directly into your /lib/libc.a file.
	either way you will want to copy the include files over
	to /usr/include (or /usr/local/include if you're willing
	to use -I/usr/local/include on all your network-software
	compiles).  something like this:
	    cp res/libresolv.a /usr/lib; ranlib /usr/lib/libresolv.a
	    tar chf - include | (cd /usr/include; tar xvpf -)

	installing the man pages is left as an exercise for the
	reader.  there are just too many different versions of
	"man" floating around for me to be able to help you figure
