Import cvs-1.9.23 as at 19980123. There are a number of really nice

things fixed in here, including the '-ko' vs. -A problem with
remote cvs which caused all files with -ko to be resent each time
(which is damn painful over a modem, I can tell you).  It also found a
heap of stray empty directories that should have been pruned with the -P
flag to cvs update but were not for some reason.

It also has the fully integrated rcs and diff, so no more fork/exec
overheads for rcs,ci,patch,diff,etc.  This means that it parses the control
data in the rcs files only once rather than twice or more.

If the 'cvs diff' vs. Index thing is going to be fixed for future patch
compatability, this is the place to do it.

+
+	* cvs.spec, Makefile.in: Fix some problems with the spec file
+	distributed with cvs.  RPM chokes on a build root of slash, so
+	that is gone now.  CVS is relocatable (as far as I know) so I
+	added a prefix tag.  The source location was incorrect and in
+	fixing that I had to add a `g' flag to one of the sed commands in
+	the Makefile.in so the spec file gets generated correctly.
+
+13 Jan 1998  Jim Kingdon
+
+	* cvsnt.mak: Add lib/fncase.c.  Plus of course the usual
+	"because Visual C++ feels like it" changes.
+
+Tue Jan 13 16:49:38 1998  Ian Lance Taylor  <ian@cygnus.com>
+
+	* acconfig.h (USE_SETMODE_STDOUT): Add undef line.
+	(HAVE_SETMODE): Likewise.

+	HAVE_SETMODE.
+	* configure, config.h.in: Regenerate.
+
+	* acconfig.h (UTIME_EXPECTS_WRITABLE): Add undef line.

+	accordingly.
+	* configure: Regenerate.
+
+Sun Jan 11 11:43:55 1998  Jim Kingdon  <kingdon@harvey.cyclic.com>
+

+	specify it here rather than be unsure which switch statement in
+	CVS to use as an example.
+
+Wed Jan  7 09:41:08 1998  Jim Kingdon  <kingdon@harvey.cyclic.com>
+

+	instead of being from Mosaic, it is from "lynx -dump -nolist".
+ 	This output is somewhat better (for example, it is formatted for
+	80 columns or so, rather than Mosaic which is rather

+Mon, 10 Nov 1997  Jim Kingdon

+
+Sun Nov  2 19:34:30 1997  Jim Kingdon  <kingdon@harvey.cyclic.com>

+	specify whether this is implemented via an "account" (whatever
+	that is) (editorial change, not run by devel-cvs).

+1997-10-28  Jim Kingdon
+
+	* .cvsignore: Add Visual C++ files du jour, namely
+	{diff,vc50}.{pdb,idb,pch}.
+
+	* cvsnt.dsp: Add files for diff library.  The custom build
+	stuff for diff/version.c and diff/diff.c was to deal with
+	there also being a src/version.c and src/diff.c.  There
+	might be an easier way.
+
+Mon Oct 27 11:21:15 1997  Jim Kingdon  <kingdon@harvey.cyclic.com>
+

+
+Thu Sep 25 14:48:26 1997  Jim Kingdon  <kingdon@harvey.cyclic.com>
+

+
+Wed Sep 24 10:35:50 1997  Jim Kingdon  <kingdon@harvey.cyclic.com>
+
+	* configure.in: Don't check for system-supplied regex matcher; see

+	* configure: Regenerated.
+
+Tue Sep 23 16:00:25 1997  Jim Kingdon  <kingdon@harvey.cyclic.com>
+

+
+	* TODO: Revise item #191 in response to xdelta 1.10 release and a
+	few other random thoughts.
+
+Sun Sep 21 17:56:28 1997  Jim Kingdon  <kingdon@harvey.cyclic.com>
+
+	* configure.in: Instead of checking for memchr, just define
+	HAVE_MEMCHR and HAVE_STRCHR.
+	Add comment about AC_FUNC_VFORK and vfork in general.
+	* acconfig.h: Add HAVE_MEMCHR and HAVE_STRCHR.
+	* configure, config.h.in: Regenerated.
+
+	* config.h.in: Regenerate using autoheader from autoconf 2.10.
+
+Sat Sep 20 01:17:10 1997  Tim Pierce  <twp@twp.tezcat.com>
+
+	[notes: (1) includes the patches to config.h.in which he sent
+	(presumably generated), (2) I have omitted a change, which was
+	sent without a ChangeLog entry, to change re_exec to
+	re_compile_pattern in configure.in, (3) Also adds diff/Makefile in
+	AC_OUTPUT -kingdon]
+
+	* Makefile.in (USOURCE_SUBDIRS, check, remotecheck, installcheck):
+	Add diff.
+
+	Note that AC_CHECK_FUNCS(vfork)
+	has been replaced by AC_FUNC_VFORK... libdiff wants the more
+	specific test, and it seems unlikely to break CVS.
+
+	* configure.in: Add AC_FUNC_CLOSEDIR_VOID, AC_FUNC_VFORK,
+	AC_STRUCT_ST_BLKSIZE.
+	(AC_CHECK_HEADERS): Add limits.h and sys/file.h.
+	(AC_REPLACE_FUNCS): Add memchr.
+	(AC_CHECK_FUNCS): Remove vfork.
+
+Fri Sep 19 09:59:33 1997  Jim Kingdon  <kingdon@harvey.cyclic.com>
+
+	* TODO: Add item #191, concerning how to store binary files.
+
+Wed Sep 17 16:13:49 1997  Jim Kingdon  <kingdon@harvey.cyclic.com>
+
+	* TESTS: Add ideas about ability to pass spaces in arguments, and
+	stdin, to the program under test, as something to consider for the
+	different test frameworks.
+
+Tue Sep 16 00:14:55 1997  Jim Kingdon  <kingdon@harvey.cyclic.com>
+
+	* BUGS: Add item about importing binary files.
+
+	* TODO: Adjust item #150 to reflect the fact that the client is
+	not quite so mean about tossing the log message as it was.
+
+Fri Sep 12 13:04:31 1997  Jim Kingdon  <kingdon@harvey.cyclic.com>
+

+
+Tue Sep  9 22:20:15 1997  Jim Kingdon  <kingdon@harvey.cyclic.com>
+
+	* README.VMS (Notes regarding compiling on VAX/VMS): Add item
+	about mode_t and pid_t.
+
+Sun Sep  7 17:34:03 1997  Jim Kingdon  <kingdon@harvey.cyclic.com>
+
+	* FAQ: Re-import from FAQ-O-Matic.  The metavariables are back.
+
+	* FAQ: Re-import from FAQ-O-Matic.  Features comment from
+	julian@whistle about update -r branch:date.  It also clobbered the
+	metavariables (confusion about "<" as data vs. HTML tag I would
+	guess), which I plan on fixing in a moment.
+
+	* configure.in: Add comment about re_exec and regexp syntax.
+
+	* configure.in (AC_REPLACE_FUNCS): Remove strdup; CVS was long
+	ago converted to use its own routine xstrdup.
+	* configure: Regenerated.
+
+Sat Sep  6 00:08:20 1997  Jim Kingdon  <kingdon@harvey.cyclic.com>
+
+	* FAQ: Re-import from FAQ-O-Matic.  In particular: GIC info
+	updated, binary files updated (e.g. -kb not -ko), rename database
+	and rCVS info updated (refer to TODO), tweaks to section on
+	contributing (HACKING, DEVEL-CVS, &c), Cyclic info updated
+	(e.g. remove Indiana address), usenet info updated
+	(e.g. comp.software.config-mgmt not gnu.*).
+
+Fri Sep  5 20:46:26 1997  Jim Kingdon  <kingdon@harvey.cyclic.com>
+
+	* FAQ: Add another introductory paragraph which talks about out of
+	date material from 1995 FAQ.
+
+	* FAQ: Re-import from FAQ-O-Matic.  This was mainly as a proof of
+	concept that I could edit the Cygnus question and have the diffs
+	come out looking right (which worked), but I also discovered that
+	the previous checkin was truncated partway through.
+
+	* FAQ: Replace file with an introductory paragraph plus a
+	downloaded copy of Molli's FAQ-O-Matic.  I believe the content
+	closely matches the 1995 Grubbs FAQ but because everything is
+	re-ordered it would be painstaking work to verify this.
+
+Thu Sep  4 17:33:53 1997  Jim Kingdon  <kingdon@harvey.cyclic.com>
+
+	* BUGS: Add item about -w global option and client/server.
+

+
+Sat Aug 30 03:17:36 1997  Noel Cragg  <noel@harvey.cyclic.com>
+
+	* TODO: Add a header so emacs chooses the correct editing mode.
+  	Made several entries more verbose (expanded some of the less
+ 	well-known acronyms and/or added pointers to further
+ 	documentation).
+
+Wed Aug 20 09:51:52 1997  Jim Kingdon  <kingdon@harvey.cyclic.com>
+
+	* INSTALL: Remove "SparcClassing" typo that has been there for

+Fri Aug 15 16:42:12 1997  Jim Kingdon  <kingdon@harvey.cyclic.com>
+

+
+Sat Aug  2 09:23:50 1997  Jim Kingdon  <kingdon@harvey.cyclic.com>
+
+	* INSTALL: In step 4, be more generic (the CVS sources are just an
+	example, and people might not have them handy).
+
+Fri Jul 25 17:02:30 1997  Jim Kingdon  <kingdon@harvey.cyclic.com>
+
+	* INSTALL: Refer to cvs.texinfo as the Cederqvist manual; that
+	seems to be the description which best applies no matter how it
+	was obtained.  Be a little more explicit about the "$" prompt
+	convention and setting environment variables.  Use double quotes
+	because they work on both DOS and Unix.
+
+Thu Jul 24 12:22:49 1997  Jim Kingdon  <kingdon@harvey.cyclic.com>
+

+
+Fri Jul 18 09:47:12 1997  Jim Kingdon  <kingdon@harvey.cyclic.com>
+
+	* TODO: Remove item 161 (the comments in cvs.texinfo have a much
+	more complete discussion of date format issues).  In item 30,
+	change "patch" to "rdiff" and expand discussion slightly.  Remove
+	item 64 (the performance issues in initial checkout have probably
+	changed quite a bit since that was written and in any event it
+	isn't particularly useful without specifics of what is slow and
+	ideas for speeding it up).
+
+	* INSTALL: Reorganize to separate out building/installing CVS
+	executables from what to do once you have them.  Adjust Visual C++
+	instructions to deal with Visual C++ 5.x.  Add brief mentions of
+	platforms other than unix and Windows.
+

+
+Sun, 22 Jun 1997  Jim Kingdon
+
+	* cvsnt.dsp: New file.  This apparently is what Visual C++ 5.0
+	uses in lieu of a .mak file (or so it seems).
+	* .cvsignore: Add cvsnt.opt cvsnt.dsw cvsnt.plg.  These seem to
+	be the generated files du jour for Visual C++ 5.0.
+
