Wed Dec 23 11:10:32 1992 Francois Pinard (pinard at icule)
From Thorsten Ohl <ohl@physics.harvard.edu>:
* wdiff.c (split_file_into_words): Call tmpnam just before opening
the file. On the Next, successive calls to tmpnam will return
different values only if the file is opened in between.
(main): Allocate temp_name statically, and initialize it to "".
On certain systems, tmpnam(NULL) causes a segmentation violation.
Length will be L_tmpman or else, PATH_MAX+1 from pathmax.h. Check
temp_name before unlinking, in case of an intervening signal.
* pathmax.h: New, from elsewhere.
* Makefile.in: Distribute pathmax.h, adjust dependencies.
* xstrdup.c, xmalloc.c: Deleted, not needed anymore.
* Makefile.in: Some cleanup before the release.
* (dvi, wdiff.dvi): New goals.
* (_wdiff.o): Use -I$(srcdir).
From Thorsten Ohl <ohl@physics.harvard.edu>:
* wdiff.c: Added two missing `break;'.
* check_it: New script, using test data from a bug report by
Robert J. Chassell <bob@gnu.ai.mit.edu>.
* testinput1, testinput2, testoutput: Deleted.
* Makefile.in: Adjusted.
Tue Dec 22 00:02:41 1992 Francois Pinard (pinard at icule)

From Colin Brough <cmb@epcc.ed.ac.uk>:
* wdiff.1: New for 0.04, replaces the previous copy.
* Makefile.in: Install the man page.
Makefile.in: Do not distribute collate.el, which lacks the
required Copyright assignment to the FSF.
Wed Dec 9 08:43:47 1992 Francois Pinard (pinard at icule)
* From David D `zoo' Zuhn <zoo@cygnus.com>:
configure.in, wdiff.c: Replace USG by HAVE_STRING_H.
* From David D `zoo' Zuhn <zoo@cygnus.com>:
Makefile.in (configure): Go to $(srcdir) before autoconf.
Sat Dec 5 15:45:25 1992 Francois Pinard (pinard at icule)
* wdiff.c: Initialize the version[] string.
* version.c: Deleted.

* From David D `zoo' Zuhn <zoo@cygnus.com>:
Makefile.in: Define MAKEINFO as makeinfo, use it.
* From Karl Berry <karl@cs.umb.edu>:
Makefile.in (realclean): Remove wdiff.info.
Makefile.in (realclean): Remove configure.
* From Karl Berry <karl@cs.umb.edu>:

Makefile.in (clean, distclean): Remove clutter for ansi2knr.
* Makefile.in (texclean): New.
* Makefile.in (check): Add a `Check successful' message.
From Colin M. Brough <cmb@epcc.ed.ac.uk>:

* Makefile.in: Distribute it.
Mon Nov 23 08:48:41 1992 Francois Pinard (pinard at icule)
* Makefile.in (dist): Get .fname from the current directory name,
instead of from version.c. I need updating many files manually,
when the version changes, version.c is just one of them.
* cbars.sh: New. By default, cbars is not part of PROGS.

Sun Nov 22 08:54:43 1992 Francois Pinard (pinard at icule)

* wdiff.c: New -n option and no_wrapping variable.
(main): Initialize and decode it.
(usage_and_exit): Announce it.
(copy_whitespace): Implement it.
Sat Nov 21 16:35:15 1992 Francois Pinard (pinard at icule)
* configure.in: Use AC_CONST.
* wdiff.c: Never define const as empty, let configure do it. Also
remove volatile declaration as empty, it is unused.
* wdiff.c, version.c: Add a few const's.
From Roland McGrath <roland@gnu.ai.mit.edu>:
* wdiff.c: Remove `const' to `char *strstr();' declaration.
From Jim Meyering <meyering@cs.utexas.edu>:
* configure.in: Avoid gdiff for X as found on SGI systems. The

and DIFF may contain spaces. Before, with PAGER='less -i'
compilation failed with unterminated string.
Tue Nov 17 18:47:23 1992 Francois Pinard (pinard at icule)
From Larry W. Virden <lvirden@cas.org>:
* Makefefile.in (check): Warn that `exit status 1' is expected.

Wed Aug 19 11:45:52 1992 Francois Pinard (pinard at icule)
From James Ganong <jeg@ced.berkeley.edu>:
* collatew.el: New, generalizes Emacs LISP `compage-windows'.
* Makefile.in: Distribute collatew.el.
* configure.in: To define DIFF, also try gnudiff and diffgnu, not
only gdiff and diff.
* ansi2knr.c: New, from Ghostscript distribution.
* unproto.l: Deleted.
* Makefile.in: Use ansi2knr instead of unproto.
* configure.in: Do not check anymore for `lex' or bad `const's.
* wdiff.c: Undefine `const' and `volatile' if not __STDC__.
* wdiff.c: Do not declare tgetstr without HAVE_TPUTS.
Tue Aug 18 03:57:06 1992 Francois Pinard (pinard at icule)
* Version 0.03 released to alt.sources and ftp.uu.net:/tmp.
* Makefile.in: Correct check goal to ignore error from wdiff.
* unproto.l: New, from ~/src. Note that flex is required.
* configure.in: Add FP_STDC_CHECK, then use it. Add AC_PROG_LEX.
* Makefile.in: Add U, apply unproto to wdiff.c and version.c if
not __STDC__.
* Makefile.in: Various corrections for being truly able to make in
subdirectories.
Mon Aug 17 14:00:03 1992 Francois Pinard (pinard at icule)
* configure.in: Check for improper `const' support.
* wdiff.c: Insure exit code values: 0 if no differences found, 1
if any difference found, 2 for other reasons or errors. Execute
`diff' even in the case absolutely no output will result.
* wdiff.c: Removed spurious comma after last enum item.
* alloca.c: New, from other GNU sources.
* configure.in: Check for alloca.
* Makefile.in: Distribute alloca.c, compile it if necessary.
Sun Aug 16 09:28:50 1992 Francois Pinard (pinard at icule)
* wdiff.c (usage_and_exit): Added -s description.
Sat Aug 15 09:27:31 1992 Francois Pinard (pinard at icule)
* Version 0.02 released to alt.sources and ftp.uu.net:/tmp.
* wdiff.c: Added -s option to produce statistics at end of output.
* wdiff.c: Copy common code from the left side instead of the
right side if only the common code and deleted words are wanted;
this makes the output spacing nicer. Also, correct a bug by which
added words were shown as common code for this option set.
* wdiff.c: PAGER_PROGRAM was previously defaulted to "more", it is
now left undefined. As currently set, the auto-configurator will
pick one, however, and force it into the program.
* wdiff.c: Avoid all emphasis if all of the output would be
emphasized the same way.
* wdiff.c: Avoid overstriking whitespace unless the pager is less.
* wdiff.c: Do termcap initialization and completion strings. If a
pager is used, insure they are sent to stdout, never to the pager.
* wdiff.c: If PAGER is defined, but to the empty string, avoid
using any pager, instead of using a default PAGER.
Fri Aug 14 19:22:30 1992 Francois Pinard (pinard at icule)
* wdiff.c: Remove the `signal (SIGCLD, SIG_IGN);' which is a
System V-ism, and rather wait() explicitely.
* wdiff.c: Declare tgetstr if <termcap.h> not included.
* Makefile.in: Have check goal works, now that -d is gone.
Wed Aug 12 01:01:37 1992 Francois Pinard (pinard at icule)
* Version 0.01 released to alt.sources and ftp.uu.net:/tmp.
* wdiff.c(setup_signals): Do not intercept SIGQUIT.
* wdiff.c: Automatically pipe through `more' or `less' if writing
to terminal, using environment variable $PAGER to override PAGER
definition. Force terminal mode, but if the pager is `less', use
printer mode. Modify copy_whitespace for overstriking whitespace
with itself in printer mode: `less' understands this.
* strstr.c: Borrowed somewhere from GNU.
* writepipe.c: New, provided by David Mackenzie.
* configure.in: Try defining PAGER to less or more. Also use our
strstr if necessary.
* Makefile.in: Transmit PAGER to program. Also handle strstr.c.
* configure.in: Try defining DIFF to gdiff or diff.
* Makefile.in: Transmit DIFF to wdiff.c, which handles it already.
* wdiff.c: Options -wxyz renamed from old -1234. New options -123
acting a little like in GNU comm utility, old -d option deleted.
* wdiff.c: Check for HAVE_TPUTS instead of HAVE_TERMCAP_H in many
places.
* configure.in: Use -ltermlib on LIBS for Xenix, -ltermcap
otherwise; once this done, test for `tputs' availability.
* COPYING.LIB: New.
* Makefile.in: Distributing COPYING.LIB.
Tue Aug 11 15:10:37 1992 Francois Pinard (pinard at icule)
* Version 0.0 released to alt.sources.
