1999-07-12 Larry Jones <larry.jones@sdrc.com>
* TESTS: Remove suspicion that setting LC_COLLATE has fixed the
problem with Solaris sort -- people are still reporting it.
1999-05-17 Jim Kingdon <http://www.cyclic.com>
(These changes were run by devel-cvs; feedback was "They look fine"
from Jim Meyering and "I concur" from Noel Cragg).
* HACKING (Submitting patches): Rewrite parts to try to sketch out
a process which is less centralized and hopefully describes the
status quo better (for example, I've mostly removed the word
"submit" because it describes a process of sending your patch to a
central authority rather than to whoever wants it). Update to
reflect some of the current practices/thinking regarding quality
and other matters. Try to be more concise where feasible.
1999-05-13 Jim Kingdon <http://www.cyclic.com>
* BUGS: Remove item about RELATIVE_REPOS not working with
client/server CVS; it must have been fixed because the testsuite
is working fine with RELATIVE_REPOS.
1999-05-07 Jim Kingdon <http://www.cyclic.com>
* TESTS: Add note about send-expect style interaction.
1999-04-26 Jim Kingdon
* cvsnt.mak: Revert to the version before today's changes
(modulo one "because the IDE feels like it" change). I
couldn't get O'Connor's cvsnt.mak to work with MSVC 4.0 at
all (I tried the IDE, which tried to wrap the makefile and
wouldn't build even with the wrap, and the command line NMAKE).
* .cvsignore: Add back cvsnt.mdp WinDebug WinRel, accordingly.
1999-04-26 Jim Kingdon <http://www.cyclic.com>
* Makefile.in (DISTFILES): Add cvsnt.dsw.
1999-04-26 (submitted 1999-03-24) John O'Connor <john@shore.net>
* cvsnt.dsw: new file. The workspace file used by MSVC 5+ to
manage multiple projects. It contains three projects: cvsnt,
zlib and diff.
* cvsnt.dsp: Fixed problem where CVS wouldn't build because of
file name conflicts. Removed all the files from zlib and diff
directories and moved to separate project files.
* cvsnt.mak: Re-generated due to the changes in cvsnt.dsp.
* .cvsignore: Removed un-used entries related to MSVC. Added
entries to cover all files generated by the NT build: *.ncb,
*.opt, *.plg, Debug and Release.
1999-04-09 Jim Kingdon <http://www.cyclic.com>
* HACKING: Add a sentence about sending patches somewhere other
than bug-cvs, while still granting permission for people to use
them under the GPL.
1999-04-08 Jim Kingdon <http://www.cyclic.com>
* configure.in (AC_OUTPUT): Remove macintosh/Makefile (overlooked
in change of 1999-02-26; thanks to Erik Bertelsen for reporting it).
* configure: Regenerated.
1999-02-26 Jim Kingdon <http://www.cyclic.com>
* macintosh: Remove this subdirectory and all its contents. It
contained MacCVS 2.x, but pretty much everyone has moved on to
MacCVS 3.x, MacCVS Pro, or MacCVSClient.

CVS uses the word "branch" in a number of ways. The two most
important are:
- The vendor branch holds releases from (normally) an outside
software vendor. It is implemented using a specific RCS branch

that does not appear in any of the RCS files or the CVS control
files.
- The CVS "default branch" is the Repository source for the

- A "magic" branch can be a branch that hasn't happened yet. It
is implemented by a special tag you can check out that is not
attached to a real RCS branch. When you commit a file to a
magic branch, the branch becomes real (i.e. a physical RCS
branch).
- And, of course, CVS uses "branch" to indicate a
human-oriented "branch in development".
How RCS uses the word "branch":
- The RCS "Main Branch" (Synonym: "The Trunk") contains a
series of two-part revision numbers separated by a single '.'
(e.g. 1.2). It is treated specially and is the initial default
branch. (The default default?)

First, install all the programs. (See Section 4A.)
Then create a Repository by executing "cvsinit", which works only from
within the head of the CVS source directory. (It needs files from the
distribution to work.)
Then create a Repository by executing "cvs -d init". (This works with
CVS 1.9.)
If you want a very primitive Repository and don't want to save a
history log, refer to modules, or use any of the "info" files for
logging, pre-commit checks, or editing templates, you can dispense
with "cvsinit" entirely. I would advise executing it.
The cvsinit program will create a short modules file containing the
module named "CVSROOT". Change to your work directory and type:
cvs checkout CVSROOT
Then read the files that are checked out.
Now you can configure your repository by checking out CVSROOT: "cvs -d
checkout CVSROOT". Change into the created directory CVSROOT. Edit the

The above suggestions are not valid when you use the pserver facility.
Be sure to read and understand the manual section about this (should
be 4.6.something). Above all: do /not/ make the repository and CVSROOT
group writeable. In CVSROOT, make `history´ group or world writeable
instead.
I suggest creating one unix group per project group. In the
repository, you would then create one directory for each group, group
writeable. New projects must then be created in these group
directories. If you don't want to say &lt;group&gt;/&lt;project&gt; on

9. While in the middle of a large "commit", how do I run other commands,
9. Why do timestamps sometimes get set to the date of the revision,
sometimes not? The inconsistency causes unnecessary recompiles.
The "checkout" command normally sets the timestamp of a working file
to match the timestamp stored on the revision in the Repository's RCS
file.
The "commit" command retains the timestamp of the file, if the act of
checking it in didn't change it (by expanding keywords).
The "update" command sets the time to the revision time the first time
it sees the file. After that, it sets the time of the file to the
current time. See 4D.8 for a reason why.
Here's a two-line PERL program to set timestamps on files based on
other timestamps. I've found this program useful. When you are certain
you don't want a source file to be recompiled, you can set its
timestamp to the stamp on the object file.

# Set timestamp of args 2nd-Last to that of the first arg.

17. Why do timestamps sometimes get set to the date of the revision,
sometimes not? The inconsistency causes unnecessary recompiles.
The "checkout" command normally sets the timestamp of a working file
to match the timestamp stored on the revision in the Repository's RCS
file.
The "commit" command retains the timestamp of the file, if the act of
checking it in didn't change it (by expanding keywords).
The "update" command sets the time to the revision time the first time
it sees the file. After that, it sets the time of the file to the
current time. See 4D.8 for a reason why.
Here's a two-line PERL program to set timestamps on files based on
other timestamps. I've found this program useful. When you are certain
you don't want a source file to be recompiled, you can set its
timestamp to the stamp on the object file.
#!/usr/local/bin/perl
#
# Set timestamp of args 2nd-Last to that of the first arg.

* Submitting patches (strategy)
* Writing patches (strategy)
Only some kinds of changes are suitable for inclusion in the
"official" CVS. Bugfixes, where CVS's behavior contradicts the
documentation and/or expectations that everyone agrees on, should be
OK (strategically). For features, the desirable attributes are that
the need is clear and that they fit nicely into the architecture of
CVS.
CVS. Is it worth the cost (in terms of complexity or any other
tradeoffs involved)? Are there better solutions?
However, if there is reason to think that a change would significantly
inconvenience any significant body of CVS users, or would be
controversial for other reasons, then the design should be re-thought.
Go back to the requirements (writing documentation might help, if you
write the documentation to explain why one would use the feature not
just what the feature does). Think about whether there is a behavior
which works in both your situation and the other situations. Make a
list of the issues (for example, submit a comment or documentation
change). Ask your coworkers, a newsgroup, or a mailing list, and see
what other people think. Distribute some experimental patches outside
the "official" CVS and see what people think. By this process, the
intention is that once-controversial changes can be refined to the
point where they are relatively uncontroversial before they are
actually checked in to the "official" CVS. Features like zlib,
encryption, and others have benefitted from this process in the past
by being mentioned in the documentation and/or discussed, before an
implementation was checked in.
If the design is not yet clear (which is true of most features), then
the design is likely to benefit from more work and community input.
Make a list of issues, or write documentation including rationales for
how one would use the feature. Discuss it with coworkers, a
newsgroup, or a mailing list, and see what other people think.
Distribute some experimental patches and see what people think. The
intention is arrive at some kind of rough community consensus before
changing the "official" CVS. Features like zlib, encryption, and
the RCS library have benefitted from this process in the past.
If longstanding CVS behavior, that people may be relying on, is
clearly deficient, it can be changed, but only slowly and carefully.

* Submitting patches (tactics)
* Writing patches (tactics)
Please include a ChangeLog entry (see the GNU coding standards for
information on writing one) with patches. Include a description of
what the patch does (sometimes the ChangeLog entry and/or comments in
the code are appropriate for this, but not always)--patches should not
be checked in unless there is some reason for them, and the
description may be helpful if there is a better way to solve the
problem. In addition to the ChangeLog entry, there should be a change
to the NEWS file and cvs.texinfo, if the change is a user-visible
change worth mentioning.
When you first distribute a patch it may be suitable to just put forth
a rough patch, or even just an idea. But before the end of the
process the following should exist:
It is nice to have a test case (see TESTS), especially for fixes which
involve subtle behaviors or twisted sections of the code.
- ChangeLog entry (see the GNU coding standards for details).
If you solve several unrelated problems, submit a separate
patch for each one. Patches should be tested before submission. Use
context diffs or unidiffs for patches.
- Changes to the NEWS file and cvs.texinfo, if the change is a
user-visible change worth mentioning.
Note that all submitted changes may be distributed under the terms of
the GNU Public License, so if you don't like this, don't submit them.
Submit changes to bug-cvs@gnu.org.
- Somewhere, a description of what the patch fixes (often in
comments in the code, or maybe the ChangeLog or documentation).
Generally speaking if you follow the guidelines in this file you can
expect a yes or no answer about whether your patch is accepted. But
even in this case there is no guarantee because wading through a bunch
of submissions can be time consuming, and noone has volunteered to
offer any such guarantee. If you don't receive an answer one way or
another within a month, feel free to ask what the status is. You can,
if you wish, distribute your patch on mailing lists or newsgroups, if
you want to make it available before it gets merged.
- Most of the time, a test case (see TESTS). It can be quite
frustrating to fix a bug only to see it reappear later, and adding
the case to the testsuite, where feasible, solves this and other
problems.
If you solve several unrelated problems, it is generally easier to
consider the desirability of the changes if there is a separate patch
for each issue. Use context diffs or unidiffs for patches.
Include words like "I grant permission to distribute this patch under
the terms of the GNU Public License" with your patch. By sending a
patch to bug-cvs@gnu.org, you implicitly grant this permission.
Submitting a patch to bug-cvs is the way to reach the people who have
signed up to receive such submissions (including CVS developers), but
there may or may not be much (or any) response. If you want to pursue
the matter further, you are probably best off working with the larger
CVS community. Distribute your patch as widely as desired (mailing
lists, newsgroups, web sites, whatever). Write a web page or other
information describing what the patch is for. It is neither practical
nor desirable for all/most contributions to be distributed through the
"official" (whatever that means) mechanisms of CVS releases and CVS
developers. Now, the "official" mechanisms do try to incorporate
those patches which seem most suitable for widespread usage, together
with test cases and documentation. So if a patch becomes sufficiently
popular in the CVS community, it is likely that one of the CVS
developers will eventually try to do something with it. But dealing
with the CVS developers may be the last step of the process rather
than the first.

* There is a new access method :fork: which is similar to :local:
except that it is implemented via the CVS remote protocol, and thus
has a somewhat different set of quirks and bugs.
* The -d command line option no longer updates the CVS/Root file. For
one thing, the CVS 1.9/1.10 behavior never had updated CVS/Root in
subdirectories, and for another, it didn't seem that popular in
general. So this change restores the CVS 1.8 behavior (which is also
the CVS 1.9/1.10 behavior if the environment variable
CVS_IGNORE_REMOTE_ROOT is set; with this change,
CVS_IGNORE_REMOTE_ROOT no longer has any effect).

CVS roots. This includes roots which are located on several servers,
or which are both remote and local. CVS will make connections to as
many servers as necessary.

* log.pl: The author commited the canonical perl "localtime" Y2K
offence, of printing "19$year" instead of (1900 + $year). Of
course, the result is non-compliance in year 2000. Fix it.
1998-10-14 Jim Kingdon
* ccvs-rsh.pl: Removed; it was not in DISTFILES so it didn't
actually get distributed. I'm going to move it to the web on the
theory that the web is a better place for such things.
* README: Don't mention it.
* Makefile.in (dist-dir, distclean): Remove references to elib.
* elib: Remove this subdirectory and all its contents. It went
with pcl-cvs, which is no longer distributed with CVS.
1998-09-22 Jim Kingdon <kingdon@harvey.cyclic.com>
* pvcs_to_rcs: Removed; it was not in DISTFILES so it didn't
actually get distributed. I'm going to move it to the web on the
theory that the web is a better place for such things.
* README: Don't mention it.
1998-09-10 Jim Kingdon
Check in Paul Eggert <eggert@twinsun.com>'s submission of
1998-08-15. I also ran "cvs admin -ko" on this file so that his
version number would be intact (not an ideal solution, because
people will import it into other repositories, but I don't feel
like hacking the master version).
* rcs2log.sh: Sync with master version at gnu.org.
1998-08-15 Jim Kingdon <kingdon@harvey.cyclic.com>
* README: Don't mention listener, since it was removed a while
ago.
* listen2.c, listen2.mak: Removed; because there is no easy way to
pass a socket (as opposed to file descriptor) from one process to
another on Windows, this isn't a promising approach (at least not
in this form).
* Makefile.in (DISTFILES): Remove them.
* .cvsignore: Remove listen2.ncb listen2.mdp Debug.
1998-05-11 W. Bradley Rubenstein
* log.pl: Check for errors from open and exec.

1999-05-06 Jim Kingdon <http://www.cyclic.com>
* Makefile.in (DISTFILES): Remove libdiff.mak.
* libdiff.mak: Removed; we are back to a single makefile for
Visual C++ version 4.
1999-04-29 Jim Kingdon <http://www.cyclic.com>
* diff.c (diff_run): Use separate statement for setjmp call and if
statement. This is better style in general (IMHO) but in the case
of setjmp the UNICOS compiler apparently cares (I don't have the
standard handy, but there are lots of legitimate restrictions on
how you can call setjmp).
1999-04-26 Jim Kingdon <http://www.cyclic.com>
* Makefile.in (DISTFILES): Add libdiff.dsp libdiff.mak .cvsignore.
1999-04-26 (submitted 1999-03-24) John O'Connor <john@shore.net>
* libdiff.dsp: new file. MSVC project file used to build the library.
* libdiff.mak: new file. Makefile for building from the command-line.
* .cvsignore: Removed un-used entries related to MSVC. Added
entries to ignore directories generated by the NT build, Debug
and Release.
1999-03-24 Larry Jones <larry.jones@sdrc.com>
and Olaf Brandes
* diff3.c (diff3_run): Use a separate stream for the input to
output_diff3_merge instead of reopening stdin to avoid problems
with leaving it open.
1999-02-17 Jim Kingdon <http://www.cyclic.com>
and Hallvard B Furuseth.
* util.c: Use __STDC__ consistently with ./system.h.
* system.h: Add comment about PARAMS.
1999-01-12 Jim Kingdon <http://www.cyclic.com>
* Makefile.in, analyze.c, cmpbuf.c, cmpbuf.h, context.c, diff.c,
diff.h, diff3.c, diffrun.h, dir.c, ed.c, io.c, normal.c, system.h,
util.c: Remove paragraph containing the old snail mail address of
the Free Software Foundation.
1998-09-21 Jim Kingdon <kingdon@harvey.cyclic.com>
* util.c (printf_output): Make msg static; avoids auto
initializer, which is not portable to SunOS4 /bin/cc.
Reported by Mike Sutton@SAIC.
1998-09-14 Jim Kingdon <kingdon@harvey.cyclic.com>
* Makefile.in (DISTFILES): Add diagmeet.note.
1998-08-15 Jim Kingdon <kingdon@harvey.cyclic.com>
* diffrun.h (struct diff_callbacks): Change calling convention of
write_output so that a zero length means to output zero bytes.
The cvs_output convention is just too ugly/error-prone.
* util.c (printf_output): Rewrite to parse format string
overselves rather than calling vasprintf, which cannot be
implemented in portable C.
1998-08-06 David Masterson of kla-tencor.com
* util.c (flush_output): Don't prototype.

1999-07-16 Tom Tromey <tromey@cygnus.com>
* cvs.texinfo (admin): Mention admin -k exception. Add cvsadmin
to index.
1999-07-14 Larry Jones <larry.jones@sdrc.com>
* cvs.texinfo (Password authentication server): Note inetd limits
and suggest using shell script to avoid.
1999-06-01 Jim Kingdon <http://www.cyclic.com>
* cvsclient.texi (Requests): For the import command, the
repository given to the Directory requests is ignored.
1999-05-27 Jim Kingdon <http://www.cyclic.com>
* cvsclient.texi (Requests): Clarify that Modified, Is-modified,
Notify and Unchanged must specify a file within the current
directory.
1999-05-24 Jim Kingdon <http://www.cyclic.com>
* cvs.texinfo (checkoutlist): New node, contains more complete
documentation of this feature.
(CVSROOT storage): Refer to the new node when mentioning
checkoutlist.
(Administrative files): Update the menu entry for Wrappers.
1999-05-17 Jim Kingdon <http://www.cyclic.com>
* cvsclient.texi (Requests): For Notify request, strike duplicate
"Response expected: no" and fix "a edit" -> "an edit".
1999-05-14 Jim Kingdon <http://www.cyclic.com>
* cvs.texinfo (Working directory storage): Try to be more clear
about the conflict field.
1999-05-11 Jim Kingdon <http://www.cyclic.com>
* cvs.texinfo (config): Use comma after @xref (thanks to Pavel
Roskin for the report/fix).
1999-05-10 Jim Kingdon <http://www.cyclic.com>
* cvsclient.texi (Requests): Document restrictions on characters
in Notify requests.
1999-05-04 Jim Kingdon <http://www.cyclic.com>
* cvs.texinfo (Password authentication security): Remove sentence
about how no one has audited pserver for holes; a lot of holes
have been closed, looking for, &c, since that was written.
In the summary, reword to reflect the fact that sniffing a
readonly password does not imply general system access (as far as
I know, of course).
* cvs.texinfo (Connection): Also suggest inetd -d.
1999-04-28 Jim Kingdon <http://www.cyclic.com>
* cvsclient.texi (Requests): Say what goes in the "watches" field
of the "Notify" request.
* cvs.texinfo (Common options): -r is for branches too.
* cvs.texinfo (Error messages): Add "no such tag" message.
(Common options): -f does not override val-tags check.
1999-04-26 Jim Kingdon <http://www.cyclic.com>
* cvs.texinfo (Locks): #cvs.rfl locks must start with "#cvs.rfl."
not just "#cvs.rfl". As far as I know CVS has always implemented
the former behavior, and this just fixes the documentation.
1999-04-23 Yoshiki Hayashi of u-tokyo.ac.jp
* cvs.texinfo (verifymsg): Correct wrong file name (bugid.edit ->
bugid.verify).
1999-04-22 Jim Kingdon <http://www.cyclic.com>
* cvsclient.texi (Responses): The text in the "M" response is not
designed for machine parsing. Likewise for "error" in regular
protocol. Likewise for "E" and "error" in authentication protocol.
1999-04-19 Jim Kingdon <http://www.cyclic.com>
* cvs.texinfo (Error messages): Add "Cannot check out files into
the repository itself".
1999-04-16 Jim Kingdon <http://www.cyclic.com>
* cvs.texinfo (Other problems): Add the Windows problem with home
directory ending in a slash.
1999-04-14 Jim Kingdon <http://www.cyclic.com>
* cvs.texinfo (CVS in repository): Include the format of the

@ -136,6 +136,36 @@ Both RCS 5.7 and current versions of CVS handle the $Log keyword in a
different way if the log message starts with "checked in with -k by ".
I don't think this behavior is documented anywhere.
Here is a clarification regarding characters versus bytes in certain
character sets like JIS and Big5:
The RCS file format, as described in the rcsfile(5) man page, is
actually byte-oriented, not character-oriented, despite hints to
the contrary in the man page. This distinction is important for
multibyte characters. For example, if a multibyte character
contains a `@' byte, the `@' must be doubled within strings in RCS
files, since RCS uses `@' bytes as escapes.
This point is not an issue for encodings like ISO 8859, which do
not have multibyte characters. Nor is it an issue for encodings
like UTF-8 and EUC-JIS, which never uses ASCII bytes within a
multibyte character. It is an issue only for multibyte encodings
like JIS and BIG5, which _do_ usurp ASCII bytes.
If `@' doubling occurs within a multibyte char, the resulting RCS
file is not a properly encoded text file. Instead, it is a byte
stream that does not use a consistent character encoding that can
be understood by the usual text tools, since doubling `@' messes
up the encoding. This point affects only programs that examine
the RCS files -- it doesn't affect the external RCS interface, as
the RCS commands always give you the properly encoded text files
and logs (assuming that you always check in properly encoded
text).
CVS 1.10 (and earlier) probably has some bugs in this area on
systems where a C "char" is signed and where the data contains
bytes with the eighth bit set.
One common concern about the RCS file format is the fact that to get
the head of a branch, one must apply deltas from the head of the trunk
to the branchpoint, and then from the branchpoint to the head of the

The term @dfn{command} means a request which expects a response (except
@code{valid-requests}). The general model is that the client transmits
a great number of requests, but nothing happens until the very end when
the client transmits a command. Although the intention is that
transmitting several commands in one connection should be legal,
existing servers probably have some bugs with some combinations of more
than one command, and so clients may find it necessary to make several
connections in some cases. This should be thought of as a workaround
rather than a desired attribute of the protocol.

specified in any previous @code{Directory} request.
Here's a more complex example, in which we request an update of a
working directory which has been checked out from multiple places in the
repository.
@example
C: Argument dir1
C: Directory dir1
C: /home/foo/repos/mod1
. . .
C: Argument dir2
C: Directory dir2
C: /home/foo/repos/mod2
. . .
C: Argument dir3
C: Directory dir3/subdir3
C: /home/foo/repos/mod3
. . .
C: update
@end example
While directories @code{dir1} and @code{dir2} will be handled in similar
fashion to the other examples given above, @code{dir3} is slightly
different from the server's standpoint. Notice that module @code{mod3}
is actually checked out into @code{dir3/subdir3}, meaning that directory
@code{dir3} is either empty or does not contain data checked out from
this repository.
The above example will work correctly in @sc{cvs} 1.10.1 and later. The
server will descend the tree starting from all directories mentioned in
@code{Argument} requests and update those directories specifically
mentioned in @code{Directory} requests.
Previous versions of @sc{cvs} (1.10 and earlier) do not behave the same
way. While the descent of the tree begins at all directories mentioned
in @code{Argument} requests, descent into subdirectories only occurs if
a directory has been mentioned in a @code{Directory} request.
Therefore, the above example would succeed in updating @code{dir1} and
@code{dir2}, but would skip @code{dir3} because that directory was not
specifically mentioned in a @code{Directory} request. A functional
version of the above that would run on a 1.10 or earlier server is as
follows:
@example
C: Argument dir1
C: Directory dir1
C: /home/foo/repos/mod1
. . .
C: Argument dir2
C: Directory dir2
C: /home/foo/repos/mod2
. . .
C: Argument dir3
C: Directory dir3
C: /home/foo/repos/.
. . .
C: Directory dir3/subdir3
C: /home/foo/repos/mod3
. . .
C: update
@end example
Note the extra @code{Directory dir3} request. It might be better to use
@code{Emptydir} as the repository for the @code{dir3} directory, but the
above will certainly work.
One more peculiarity of the 1.10 and earlier protocol is the ordering of
@code{Directory} arguments. In order for a subdirectory to be
registered correctly for descent by the recursion processor, its parent
must be sent first. For example, the following would not work to update
@code{dir3/subdir3}:
@example
. . .
C: Argument dir3
C: Directory dir3/subdir3
C: /home/foo/repos/mod3
. . .
C: Directory dir3
C: /home/foo/repos/.
. . .
C: update
@end example
The implementation of the server in 1.10 and earlier writes the
administration files for a given directory at the time of the
@code{Directory} request. It also tries to register the directory with
its parent to mark it for recursion. In the above example, at the time
@code{dir3/subdir3} is created, the physical directory for @code{dir3}
will be created on disk, but the administration files will not have been
created. Therefore, when the server tries to register
@code{dir3/subdir3} for recursion, the operation will silently fail
because the administration files do not yet exist for @code{dir3}.

@item
The current procedure for @code{cvs update} is highly sub-optimal if
there are many modified files. One possible alternative would be to
have the client send a first request without the contents of every
modified file, then have the server tell it what files it needs. Note
the server needs to do the what-needs-to-be-updated check twice (or
more, if changes in the repository mean it has to ask the client for
more files), because it can't keep locks open while waiting for the
network. Perhaps this whole thing is irrelevant if there is a multisite
capability (as noted in @sc{todo}), and therefore the rcsmerge can be
done with a repository which is connected via a fast connection.

* getopt.h: Don't declare the arguments to getopt.
1999-02-09 Jim Kingdon <http://www.cyclic.com>
* vasprintf.c: Removed; there is apparently no clean, portable
solution to the VA_LIST_IS_ARRAY problem (C9X drafts have va_copy,
but we aren't even assuming C90 yet!).
* Makefile.in (SOURCES): Remove vasprintf.c.
* build_lib.com: Remove vasprintf.c and vasprintf.obj.
1999-01-26 Jim Kingdon <http://www.cyclic.com>
and Joerg Bullmann <http://www.glink.net.hk/~jb/MacCVSClient/>
* fnmatch.c: Use FOLD_FN_CHAR in two cases where it had been
omitted.
1999-01-22 Jim Kingdon <http://www.cyclic.com>
* fnmatch.c: Include system.h; FOLD_FN_CHAR has moved there from
config.h (from Alexey Milov). Don't define our own FOLD_FN_CHAR;
that just masks cases in which we got the includes tangled up.
1999-01-12 Jim Kingdon <http://www.cyclic.com>
* memmove.c: Remove paragraph which contained the FSF's old
snail mail address; it has changed.
1999-01-05 Jim Kingdon <http://www.cyclic.com>
* md5.c, md5.h: Rename all the external interfaces to start with
cvs_* to avoid namespace pollution problems. Include string.h
unconditionally, to avoid gcc -Wall warnings on memset.
1998-12-29 Jim Kingdon <http://www.cyclic.com>
* getdate.y (RelativeMonth): Add 1900 to tm_year, so that in 2000,
we pass 2000, not 100, to Convert.
(Convert): Add comment about Year argument.
* getdate.c: Regenerated using byacc.
Tue Mar 24 16:08:00 1998 Ian Lance Taylor <ian@cygnus.com>

Note that the order of the line is not significant; CVS is free to
rearrange them at its convenience.
There is currently no way of quoting tabs or linefeeds in the
