+Sat Nov 05 08:35:25 1994  Jim Meyering  (meyering@comco.com)
+
+	* Version 1.12.
+
+Fri Nov 04 06:01:00 1994  Jim Meyering  (meyering@comco.com)
+
+	* Version 1.11.
+
+Wed Nov 02 18:52:20 1994  Jim Meyering  (meyering@comco.com)
+
+	* doc/Makefile.in (install): Remove test for existence of info
+	file.  Simply change to $(srcdir) instead.
+
+Wed Oct 26 23:40:07 1994  Jim Meyering  (meyering@comco.com)
+
+	* safe-xstat.hin [EINTR]: Always define safe_l?stat.
+	Define it __static -- which is `static' for most includers,
+	but `/* empty */' for safe-xstat.cin.
+	* safe-xstat.cin: Define __static to nothing so we get public
+	safe_l?stat functions in the library.
+
+	* Makefile.in (All actions invoking $(MAKE) from within compound
+	(e.g. `for') sh statements): Exit non-zero if the sub-make fails.
+	Otherwise, the top-level make may exit successfully when it should
+	fail.  From Jim Kingdon (kingdon@cygnus.com).
+
+Sun Oct 23 23:36:26 1994  Jim Meyering  (meyering@comco.com)
+
+	* safe-xstat.hin: Don't use a statement expression here.
+	Use an inline function instead.
+	* safe-xstat.cin: Don't duplicate the definition of safe_l?stat here.
+	Get the definition from safe-xstat.hin.
+
+Fri Oct 21 00:57:23 1994  Jim Meyering  (meyering@comco.com)
+
+	* man/Makefile.in: Fix typo that had su.1 being installed as
+	`man/man1/.1'.  From Kjetil Torgrim Homme.
+
+	* basename.c, dirname.c, expr.c, pathchk.c, sleep.c (main): Diagnose
+	wrong number of argument -- usually too few -- instead of just
+	referring the user to the --help option.  Reported by Karl Berry.
+
+Mon Oct 17 23:55:41 1994  Jim Meyering  (meyering@comco.com)
+
+	* doc/Makefile.in (install): Install the info files from either
+	the source directory or the object directory.
+	From Ian Lance Taylor (ian@cygnus.com).
+
+Sun Oct 16 12:14:02 1994  Jim Meyering  (meyering@comco.com)
+
+	* lib/Makefile.in (distclean): Don't delete getdate.c and posixtm.c
+	here since they are not distributed.
+	(realclean): Delete them here instead.
+	From Francois Pinard.
+
+Mon Oct 10 21:44:42 1994  Jim Meyering  (meyering@comco.com)
+
+	* id.c (print_group_list, print_full_info): Use more precise
+	feature tests.  Rather than assuming that a definition for
+	NGROUPS_MAX implies the existence of the getgroups function,
+	test for HAVE_GETGROUPS explicitly.
+	* su.c (log_su): Likewise.  Similarly, check HAVE_INITGROUPS.
+	Both from Kaveh Ghazi.  He reported that a Pyramid 9820 OSx 5.0d
+	(Dual universe SVR3/BSD4.2) system had NGROUPS_MAX and syslog.h
+	but not getgroups, initgroups or the syslog functions.
+
+Fri Oct 07 19:42:35 1994  Jim Meyering  (meyering@comco.com)
+
+	* doc/Makefile.in (sh-utils.dvi): Depend on version.texi.
+	* version.texi: Use RELEASEDATE, not RELEASE_DATE.
+	* sh-utils.texi: Likewise.
+
+	* configure.in: Test for crypt in -lcrypt for NetBSD.
+	Reported by Greg Hudson (ghudson@mit.edu).
+
+	* system.h: Don't define lstat.  safe-l?stat.h does that now.
+
+Thu Oct 06 21:14:07 1994  Jim Meyering  (meyering@comco.com)
+
+	* src/Makefile.in (link_command): Remove $(CFLAGS).  Because
+	the default value usually includes -g, Linux users were getting
+	statically linked executables.  With this removal they'll get
+	much smaller, dynamically linked ones by default.
+
+	* lib/Makefile.in (safe-lstat.o): Depend on safe-stat.h, too.
+
+Sun Oct 02 16:15:32 1994  Jim Meyering  (meyering@comco.com)
+
+	* src/Makefile.in: Don't use binprefix.  Use autoconf-2's
+	@program_transform_name@ instead.
+	* man/Makefile.in: Likewise for manprefix.
+
+	* safe-xstat.hin [!S_ISLNK]: Include safe-stat.h and define
+	SAFE_LSTAT and safe_lstat to their symlink-ignorant counterparts.
+	* lib/Makefile.in (extract_lstat, extract_stat): Add sed rules to
+	extract the new cpp directives into safe-lstat.h, but not into
+	safe-stat.h.
+
+Sat Oct 01 00:14:10 1994  Jim Meyering  (meyering@comco.com)
+
+	* system.h: Remove conditional definition of mode_t.
+	configure takes care of this now.
+
+	* configure.in: Add -l$lib (not $lib) to LIBS when checking
+	for syslog.  From Kaveh Ghazi.
+
+	* date.c (batch_convert): Use K&R style function definition.
+	From Kaveh Ghazi.
+
+	* date.c (main): When reading dates from a file with a +FORMAT-style
+	user-specified format, don't print the leading `+'.  Franc,ois Pinard
+	noticed this problem.
+	Make an error message clearer.  From Franc,ois.
+
+	* lib/Makefile.in (DISTFILES): Add getline.h.
+	(SOURCES, OBJECTS): Add getline.c, getline.o.
+
+	* safe-xstat.hin: Don't include <sys/types.h> or <sys/stat.h>.
+	Otherwise, we'd lose when the includer has already included
+	<sys/stat.h> on systems that aren't protected against multiple
+	inclusion.  Add a note that those headers must be included before
+	this one.  Don't include <config.h> either.
+	* safe-xstat.cin: Include <sys/types.h> and <sys/stat.h> here instead.
+	Include <config.h> here, too.
+	Kaveh Ghazi reported this problem.
+
+Fri Sep 30 22:40:21 1994  Jim Meyering  (meyering@comco.com)
+
+	* date.c (main): Accept new option: (-f) --file=datefile.
+	(batch_convert): New function.  Suggested by Karl Berry.
+
+	* date.c (main): Diagnose use of conflicting options.
+	Revamp non-option argument processing.
+	Detect write errors.
+
+	* lib/*.c, src/*.c: Remove CONFIG_BROKETS conditional.
+	* lib/Makefile.in src/Makefile.in: Don't define it.
+
+	configure.in (AC_CHECK_FUNCS): Add getcwd.  From Kaveh Ghazi.
+
+	* safe-xstat.c.in, safe-xstat.h.in: Rename to safe-xstat.cin and
+	safe-xstat.hin so the names don't exceed the 14-character limit.
+	Reported by Kaveh Ghazi.
+
+Mon Sep 26 19:49:40 1994  Jim Meyering  (meyering@comco.com)
+
+	* configure.in: Don't use $su_cv_sys_tiocgwinsz_in_termios_h
+	uninitialized.  From R. Bernstein <rocky@panix.com> and Kaveh Ghazi.
+	(NICE_PRIORITY): Fix typo that caused omission from PROGS of nice
+	and nohup on systems with nice but not setpriority.
+	From Andreas Schwab.
+
+Sat Sep 24 10:13:00 1994  Jim Meyering  (meyering@comco.com)
+
+	* Makefile.in (stamp-h.in): Create using echo, not date.
+	Using the latter could easily lead to rcs/cvs merge conflicts.
+	* configure.in (stamp-h): Ditto, though this is less important
+	because stamp-h isn't distributed.
+
+	* nice.c (main): Revamp option processing to detect options
+	like `--7' manually and pass the rest off to getopt_long.
+	(isinteger): Use ISDIGIT.
+	Use parse_long_options.
+
+	* system.h: Include <ctype.h> and add IS* macros.
+	* expr.c: Don't include <ctype.h> or define IS* macros since
+	system.h now does that.
+	* printf.c: Ditto.
+
+	* date.c (usage): Add description of numeric modifiers.
+
+	* printf.c (print_formatted): Declare DIREC_LENGTH size_t, not int.
+	(print_esc_string): Ditto for LENGTH.
+	* dirname.c (main): Cast string literal to (char*).
+	* stty.c (wrapf): Declare first argument const char *.
+	* tee.c (main, tee): More const dcls and casting.
+	* who.c (read_utmp): New variable: size to avoid type warnings.
+	All of these eliminate compilation warnings reported by
+	Franc,ois Pinard.
+
+	* doc/Makefile.in (DISTFILES): Add version.texi because generating
+	that file now depends on having a version of date that can handle
+	formats like `+%Y %B'.
+	(version.texi): Generate RELEASE_DATE, too.
+	* sh-utils.texi: Use RELEASE_DATE instead of hard-coded date.
+
+	* long-options.h: Prepend underscores to arg names in prototype
+	to avoid warnings about shadowing.
+
+	* src/Makefile.in: Add dependencies on long-options.h.
+
+	* configure.in: Make having autoconf-1.120 a prerequisite.
+
+	* sh-utils.texi [INFO-DIR-ENTRY]: Add an entry for each `invoking'
+	node.  Regularize punctuation, indexing, and xrefs.
+	From Franc,ois Pinard.
+
+	* date.c (usage): Tweak the usage message a little.
+	Add `const' to more dcls.
+
+	* stty.c: Add `const' to more dcls.
+	* su.c: Ditto.
+	* who.c: Ditto.
+
+	* tee.c (main): Use _POSIX_SOURCE, not _POSIX_VERSION.
+
+Sat Sep 17 15:48:10 1994  Jim Meyering  (meyering@comco.com)
+
+	* (doc): New subdirectory with texinfo documentation.
+	Thanks to Franc,ois Pinard and Karl Berry!
+	Note however that it contains mainly the information from the
+	`man' pages, so it is not good documentation.  But this way,
+	at least we don't have to maintain the troff man pages anymore.
+
+	* su.c: Test !HAVE_ENDGRENT and !HAVE_ENDPWENT rather than
+	_POSIX_SOURCE to determine whether endgrent and endpwent should
+	be defined away.
+	* configure.in (AC_CHECK_FUNCS): Add endgrent and endpwent.
+
+	* who.c: Test HAVE_SYS_PARAM_H rather than _POSIX_SOURCE
+	to determine whether <sys/param.h> should be included.
+
+	* date.c (main): Rewrite command-line argument handling code
+	to give diagnostics for inconsistent options.
+
+	* Makefile.in: Restructure dependencies using local-*
+	and recursive-* targets to avoid evil double-colon rules.
+	Although the actions assiciated with double-colon rules are
+	run sequentially using GNU make-3.71, POSIX doesn't guarantee
+	that behavior.	The next release may run them in parallel.
+	Running the old rules in parallel would sometimes delete
+	config.status before it was used in a subdirectory make.
+	With several suggestions from Franc,ois Pinard.
+
+Thu Sep 15 19:10:51 1994  Jim Meyering  (meyering@comco.com)
+
+	* stty.c [VWERSE && !VWERASE]: Define VWERASE for AIX-3.2.5.
+
+Sat Sep 03 00:41:53 1994  Jim Meyering  (meyering@comco.com)
+
+	* lib/Makefile.in (safe-lstat.c, safe-lstat.h, safe-stat.c,
+	safe-stat.h): Use $(srcdir) to find source files.
+	(.c.o): Use -I. to get safe-lstat.h and safe-stat.h from the
+	build directory.
+	* src/Makefile.in (incl): Add -I../lib to get lib/safe-lstat.h and
+	lib/safe-stat.h from the build directory.  From Michael I Bushnell
+	<mib@geech.gnu.ai.mit.edu>.
+
+	* Makefile.in: Remove rules to create installation directories.
+	* {src,man}/Makefile.in: Put them here instead.
+
+	* configure.in: Update to take advantage of autoconf 2.0 features.
+
+Sat Aug 27 16:57:20 1994  Jim Meyering  (meyering@comco.com)
+
+	* system.h [BROKEN_STAT_MACROS]: Remove unnecessary #ifdef's.
+	From Francois Pinard.
+
+Thu Aug 18 11:44:48 1994  Jim Meyering  (meyering@comco.com)
+
+	* su.1: Explain why GNU doesn't support the `wheel group'.
+
+Mon Aug 01 21:58:14 1994  Jim Meyering  (meyering@comco.com)
+
+	* date.c: Add --utc option.  It will supercede --uct.
+	Change references to `universal coordinated time' to
+	correct `coordinated universal time'.  From Harris Boldt Edelman
+	<hbe@red-eft.la.ca.us>.
+	* date.1: Correct the documentation, too.
+
+	* date.c (main, show_date): For -u, use gmtime instead of relying on
+	localtime's ability to interpret the TZ enviroment variable.
+	`date -u' failed (by reporting local time) on romp-ibm-bsd and PCs
+	(DOS and OS/2) running emx 0.8h.  From R. Bernstein
+	<rocky@watson.ibm.com>.
+
+Sat Jul 30 07:52:27 1994  Jim Meyering  (meyering@comco.com)
+
+	* nohup.sh: Separate `nice -5' from COMMAND with `--' to ensure
+	that COMMAND isn't interpreted as an option to nice.
+	* groups.sh: Similarly, separate each name from `id -Gn' with `--'.
+	Karl Berry pointed out that `groups --help user' gave confusing
+	diagnostics.
+
+Tue Jul 26 11:33:53 1994  Jim Meyering  (meyering@comco.com)
+
+	* su.c (main): Make copies of the password information we'll use
+	so that log_su (through getlogin) doesn't clobber the static data.
+	With suggestions from Francois Pinard.
+
+	* system.h: Remove `|| defined(_POSIX_VERSION)' from test that
+	decides whether to include <fcntl.h>.  From Francois Pinard.
+
+Mon Jul 25 23:54:36 1994  Jim Meyering  (meyering@comco.com)
+
+	* pathchk.c (dir_ok): Use SAFE_STAT.
+	* test.c (test_stat, binary_operator, unary_operator): Use SAFE_STAT
+	and SAFE_LSTAT.
+	* who.c (print_entry):  Use SAFE_STAT.
+
+	* test.c (group_member): Remove function.  Use the one broken out
+	into group-member.c instead.
+
+Fri Jul 15 00:23:17 1994  Jim Meyering  (meyering@comco.com)
+
+	system.h: Remove unneeded decls of atof and atol.
+
+Fri Jul 08 01:09:23 1994  Jim Meyering  (meyering@comco.com)
+
+	stty.c (main): Initialize max_col (used by wrapf) before calling
+	display_speed.  Otherwise, `stty speed' output a spurious newline.
+	From Andreas Schwab <schwab@issan.informatik.uni-dortmund.de>.
+
+Sun Jul 03 08:44:00 1994  Jim Meyering  (meyering@comco.com)
+
+	* configure.in [AC_HAVE_HEADERS]: Add sys/param.h, for
+	definition of HAVE_SYS_PARAM_H, now tested in pathmax.h.
+
+	* configure.in [AC_WORDS_BIGENDIAN]: Add it.  This macro is
+	required by memcmp.c on big-endian systems.  Its absence was
+	diagnosed by Lars Duening (duening@ibr.cs.tu-bs.de).
+
+Sun Jun 19 00:18:06 1994  Jim Meyering  (meyering@comco.com)
+
+	* nice.c (main): Accept options like `--5' (equivalent to `-n -5')
+	instead of letting getopt give an `unrecognized option' error.
+
+	* long-options.c: Require another argument: version_string.
+	Don't include "version.h" or "system.h".
+	* basename.c, dirname.c, echo.c, expr.c, hostname.c, printf.c,
+	pwd.c, stty.c, test.c, yes.c: Adjust callers of parse_long_options
+	accordingly.
+
+Thu Jun 02 14:11:31 1994  Jim Meyering  (meyering@comco.com)
+
+	* stty.c (main): Set max_col and current_col before running
+	display_window_size.  Otherwise, `stty size' output a spurious
+	newline.  From Bauke Jan Douma (bjdouma@xs4all.hacktic.nl).
+
+Mon May 30 09:33:53 1994  Jim Meyering  (meyering@comco.com)
+
+	* test.c (test_syntax_error, beyond): Add __attribute__ ((noreturn))
+	so gcc will know enough not to give warnings.
+
+Sun May 29 17:40:21 1994  Jim Meyering  (meyering@comco.com)
+
+	* long-options.c: Move from src/ to lib/.
+	* long-options.h: Ditto.
+	* src/Makefile.in: Remove references to long-options.[ch].
+	* lib/Makefile.in (SOURCES, OBJECTS): Add long-options.[co].
+
+Fri May 27 18:20:18 1994  Jim Meyering  (meyering@comco.com)
+
+	* stty.c [VFLUSH && !VFLUSHO]: Define VFLUSH0.
+	Ultrix's termios.h defines VFLUSH, but not VFLUSHO.
+	From Kjetil Torgrim Homme <kjetilho@ifi.uio.no>.
+
+Thu May 26 08:46:32 1994  Jim Meyering  (meyering@comco.com)
+
+	* configure.in [INSTALL]: Revert change of March 8.  autoconf
+	has fixed this.
+
+Thu May 19 01:10:20 1994  Jim Meyering  (meyering@comco.com)
+
+	* Version 1.10.
+
+	* lib/Makefile.in (DISTFILES): Add getdate.c and posixtm.c.
+
+	* src/Makefile.in (users.c): Use cp if hard link fails.
+	From Ian Lance Taylor.
+
+	* Makefile.in (dist): Change package name from shellutils to sh-utils.
+	That allows a hyphen and 5-character version number without exceeding
+	the 14-character limit on file name length.  shellutils-1.10 would
+	have been too long.
+	* version.c: Update package name.
+
+	* hostname.c: Include <sys/types.h> before "system.h".
+	From Kaveh Ghazi and Karl Berry.
+
+	* hostname.c (sethostname) [!HAVE_SETHOSTNAME && HAVE_SYSINFO &&
+	HAVE_SYS_SYSTEMINFO_H && HAVE_LIMITS_H]: New function.  SVR4 systems
+	prefer sysinfo over sethostname.
+	* configure.in (AC_HAVE_FUNCS): Add sysinfo.
+	(AC_HAVE_HEADERS): Add sys/systeminfo.h.
+	From Kaveh Ghazi.
+
+Fri May 13 09:45:23 1994  Jim Meyering  (meyering@comco.com)
+
+	* lib/xgethostname.c (xgethostname): Call xmalloc outside the loop.
+	Correct loop termination condition.
+
+	* pwd.c: Include <sys/types.h> before "system.h".
+	From Kaveh Ghazi.
+
+	* {lib,man,src}/Makefile.in (Makefile): Use ../config.status
+	instead of $(srcdir)/../config.status.  The latter didn't work
+	for builddir != srcdir.  From Kaveh Ghazi.
+
+	* Makefile.in (Makefile): Remove dependencies on */Makefile.in.
+	Change the rule so running config.status creates only Makefile.
+	(stamp-config): Have config.status generate only config.h.
+
+	* {lib,man,src}/Makefile.in (Makefile): Add single dependency on
+	Makefile.in and rule to make config.status create only Makefile.
+
+	* hostname.c: New program.
+	* hostname.1: New file.
+	* Makefile.in (PROGS): Add hostname.
+	(SOURCES): Add hostname.c
+	* src/Makefile.in: Add rules and dependencies for hostname.
+	* configure.in (AC_HAVE_FUNCS): Add sethostname.
+
+	* pathchk.c (validate_path) [lint]: Initialize a variable to
+	suppress `used before initialized' warning.
+
+	* who.c: Correct gethostname prototype to indicate the function
+	returns int, not char.
+
+Sun May 01 08:38:18 1994  Jim Meyering  (meyering@comco.com)
+
+	* who.c: Add #ifdefs to build the `users' executable.
+	* src/Makefile.in: Add corresponding rules.
+	* Makefile.in (PROGS): Add users.
+	From Kaveh R. Ghazi <ghazi@noc.rutgers.edu>.
+	* users.1: Document it.
+
+Thu Apr 28 00:45:02 1994  Jim Meyering  (meyering@comco.com)
+
+	* pwd.c: New program.
+	* pwd.1: New file.
+	* Makefile.in (PROGS): Add pwd.
+	* lib/Makefile.in: (DISTFILES): Add pathmax.h.
+	(SOURCES, OBJECTS): Add xgetcwd.c and xgetcwd.o respectively.
+	* src/Makefile.in: Add rules and dependencies for pwd.
+
+	* yes.c: Don't include version.h.
+
+Mon Apr 18 19:54:24 1994  Jim Meyering  (meyering@comco.com)
+
+	* documentation: Change uses of `pathname' and `path' as per
+	GNU standards.
+
+	* long-options.c (parse-long-options): Take a new argument,
+	command_name, for use in --version output.
+	* basename.c, dirname.c, echo.c, expr.c, printf.c, stty.c, test.c,
+	yes.c (main): Update callers.
+
+Wed Mar 30 08:53:21 1994  Jim Meyering  (meyering@comco.com)
+
+	* configure.in: Use AC_SET_MAKE.
+	* Makefile.in: Edit MAKE assignments into @SET_MAKE@.
+
+Fri Mar 25 01:13:42 1994  Jim Meyering  (meyering@comco.com)
+
+	* configure.in: Use AC_VERBOSE, AC_CHECKING, and AC_WARN instead
+	of explicit echo commands.
+	When checking for shadow password routines, make sure the function
+	getspnam is available before defining HAVE_SHADOW_H.
+	<dvldbg@cs.umu.se> reported that shadow.h exists on some
+	linux system that did not have the function.
+
+Tue Mar  8 10:29:13 1994  Jim Meyering  (meyering@comco.com)
+
+	* configure.in [INSTALL]: When AC_PROG_INSTALL resorts to setting
+	this to `./install.sh', make it `../install.sh' instead since that
+	script will be invoked only from subdirectories.
+	[WINSIZE_IN_PTEM]: Check for this unconditionally, rather than
+	only when TIOCGWINSZ is not defined through termios.h.  The old
+	method loses on SCO ODT 3.0 systems.
+
+Sat Feb 19 14:23:14 1994  Jim Meyering  (meyering@comco.com)
+
+	* Version 1.9.4.
+
+	* stty.c (main): Use getopt_long_only with "ag" instead of
+	getopt_long with "".  The latter incremented optind so the
+	-a and -g options weren't recognized.
+
+	* Version 1.9.3.
+
+Tue Feb 15 18:28:28 1994  Jim Meyering  (meyering@comco.com)
+
+	* stty.c (main): Use getopt only to recognize long options.
+	Hand code the loop to detect -a, -g, -ag and -ga.  Using getopt
+	to detect the short options loses (because we have to ignore
+	unrecognized options and we are allowing GNU getopt to permute)
+	because e.g. `-tabs' is interpreted as a group of options, one of
+	which is `-a'.  Before, running `stty -tabs echo' gave this error:
+	  stty: when specifying an output style, modes may not be set
+	Reported by Arne H. Juul.
+
+Sun Feb 13 13:34:25 1994  Jim Meyering  (meyering@comco.com)
+
+	* basename.1, dirname.1, stty.1: Reflect usage changes.
+	* basename.c, dirname.c, stty.c (usage): Ditto.
+
+	* long-options.h (parse_long_options): Invoke usage function
+	argument with explicit dereference as per GNU coding standards.
+
+	* basename.c dirname.c: Use parse_long_options instead of the
+	conventional getopt_long paradigm.  Before, the commands
+	`basename file-dist -dist' and `basename -- file.c .c' produced
+	incorrect results.  Now, even `basename -file-dist -dist' works
+	and the command `basename -- file.c .c' fails for the right
+	reason: the `--' is not a special (to getopt) token for these
+	commands.  It is interpreted as the filename, so there are too
+	many arguments to basename.  Rick Sladkey <jrs@world.std.com>
+	reported the problem with basename.
+
+	* stty.c (set_window_size): When stty fails to get the window size
+	(as happens on telnet sessions to Solaris systems), initialize all
+	fields of the winsize struct.  Before, it was using the uninitialized
+	pixel fields of the struct in the ioctl to set window size parameters.
+	From Rick Sladkey.
+
+	* stty.c (main): Use parse_long_options to handle --help and --version.
+	(main): In the remaining getopt_long loop, don't jump out of the
+	loop from the `default' branch of the switch statement.  Doing that
+	left optind in an inconsistent when there were non-option arguments
+	preceding `reversed' arguments (e.g. stty echo -echoe) and the
+	preceding non-option arguments were ignored.  Rick Sladkey reported
+	that stty was ignoring arguments.
+
+	* stty.c (main): Fail with a diagnostic when both -g and -a are given.
+	(main): Fail with a diagnostic when either -g or -a is used with
+	arguments for setting modes.
+
+Fri Feb 11 19:39:37 1994  Jim Meyering  (meyering@comco.com)
+
+	* stty.c (get_win_size): Don't use an ANSI-style function
+	definition.  From Kaveh R. Ghazi <ghazi@noc.rutgers.edu>.
+
+Thu Feb 10 01:22:37 1994  Jim Meyering  (meyering@comco.com)
+
+	* stty.c [CSWTCH] (__sparc__ && __svr4__): Define `swtch' to
+	_POSIX_VDISABLE by default.  Otherwise, the default settings on
+	SunOS 5.3 (from /usr/include/sys/termios.h) have both `swtch'
+	and `susp' set to ^Z.  Those default settings are not unusual.
+	What is unusual is that with such settings on SunOS 5.3, the tty
+	driver doesn't generate a signal for control-Z.  Reported by
+	Brent Wiese <brent@dot.imgen.bcm.tmc.edu>.
+
+	* stty.c (main) [CIBAUD]: Don't report an error on SunOS 4.1.x
+	systems if the only difference is in this nybble of c_cflag.
+	See the comments for the gory details.  Thanks to
+	Erez "HWank1" Zadok <ezk@cs.columbia.edu> for reporting this
+	and helping me reproduce it.
+
+Tue Feb 01 00:59:56 1994  Jim Meyering  (meyering@comco.com)
+
+	* stty.c (main): Call tcsetattr only if we've updated tty modes,
+	not e.g. if we've changed the window size.
+
+	* Update Copyright dates in src/*.
+
+Fri Jan 28 11:02:21 1994  Jim Meyering  (meyering@comco.com)
+
+	* configure.in: Don't set LDFLAGS since linking now uses both
+	LDFLAGS and CFLAGS.
+
+Wed Jan 26 10:54:02 1994  Jim Meyering  (meyering@comco.com)
+
+	* stty.c (get_win_size): New function.  Try getting size first
+	for the device on stdout.  Try stdin only if that fails.  Suggested
+	by Andreas Schwab <schwab@issan.informatik.uni-dortmund.de>.
+	(set_win_size): Call get_win_size instead of calling ioctl directly.
+	(display_window_size): Ditto.
+	(screen_columns): Ditto.
+
+Mon Jan 24 22:57:18 1994  Jim Meyering  (meyering@comco.com)
+
+	* stty.c (set_window_size): Work around SunOS 4.x kernel bug that
+	makes `stty rows 34 cols 80;stty rows 0;stty cols 0' incorrectly
+	set rows to 80 and columns to 0.  Sun's stty has this problem, too.
+	The kernel bug is fixed in Solaris 2.  Mostly from Alexander Dupuy
+	<dupuy@cs.columbia.edu>.
+
+	* src/Makefile.in: Use both LDFLAGS and CFLAGS when linking.
+	* man/Makefile.in: Use binprefix as the default manprefix.
+
+	* nohup.sh: Redirect usage message to stderr.
+	From Andreas Schwab <schwab@issan.informatik.uni-dortmund.de>.
+
+Thu Jan 13 17:27:38 1994  Jim Meyering  (meyering@comco.com)
+
+	* src/Makefile.in: Change all link commands to use both $(CFLAGS)
+	and $(LDFLAGS).
+
+Mon Jan 10 01:20:38 1994  Jim Meyering  (meyering@comco.com)
+
+	* man/Makefile.in (manprefix): Use binprefix as the default.
+
+Thu Jan 06 18:19:06 1994  Jim Meyering  (meyering@comco.com)
+
+	* who.c (print_entry): Prepend `/dev/' only if ut_line is not
+	already an absolute filename.  Just to be safe.
+
+Fri Dec 31 00:22:59 1993  Jim Meyering  (meyering@comco.com)
+
+	* date.c (usage): Reorder listing of % formats in `sort -f' order.
+
+Tue Dec 28 15:49:32 1993  Jim Meyering  (meyering@comco.com)
+
+	* install.sh: New file.
+	Makefile.in [DISTFILES]: Add it.
+
+	* who.c (read_utmp): Use stdio functions instead of open/read/close
+	to avoid having to handle POSIX read's -1/errno=EINTR failure case.
+
+	* tee.c (tee): A POSIX implementation of the read system call
+	may return -1 and set errno to EINTR when it is interrupted.
+	Retry instead of failing with an error.
+	(tee): Don't use xwrite.  Use full_write instead and include the
+	losing file name in the message reporting a write failure.
+	Don't treat standard output as a special case, so a failed write
+	to stdout doesn't exit immediately.
+
+	* date.c (usage): Note that for %w, 0 corresponds to Sunday.
+
+Sat Dec 25 23:15:58 1993  Jim Meyering  (meyering@comco.com)
+
+	* who.c (main): Don't chdir ("/dev") for the stat in print_entry.
+	(print_entry): Instead of stat'ing the /dev-relative path, ut_line,
+	stat the absolute path with "/dev/" prefix.  From David MacKenzie.
+
+Wed Dec 22 00:53:51 1993  Jim Meyering  (meyering@comco.com)
+
+	* expr.c (toarith): Interpret the empty string as just that
+	rather than as the integer zero.
+	Before, `expr "" == 0' output 1.  Now it prints 0.
+
+	* configure.in (AC_HAVE_HEADERS): Check for float.h for strtod.c.
+
+	* configure.in (check for TIOCGWINSZ): Don't look in sys/ioctl.h
+	or sys/ptem.h if we've already found it in termios.h.  This
+	eliminates redefinition warnings from including both termios.h
+	and sys/ioctl.h on sytems running SunOS.  From Matthew Seaman
+	(matthew@dyson.ox.ac.uk).
+
+	* date.1: Document new %s format and old `-' and `_' numeric field
+	modifiers.
+
+	* memcmp.c: Use the latest version from GNU C library.
+
+Mon Dec 20 23:29:30 1993  Jim Meyering  (meyering@comco.com)
+
+	* configure.in [test for 8-bit clean memcmp]: Add a test to detect
+	losing memcmp from SunOS4.1.x.  From Robert H. de Vries
+	<robert@and.nl>.
+
+Sat Dec 18 01:12:24 1993  Jim Meyering  (meyering@comco.com)
+
+	* configure.in (AC_OUTPUT): Put `touch stamp-config' in second arg
+	so it goes in config.status.  This eliminates unnecessary second run
+	of configure.
+
+Fri Dec 10 01:06:28 1993  Jim Meyering  (meyering@comco.com)
+
+	* stty.c (screen_columns): Instead of dying just because Solaris'
+	`ioctl (0, TIOCGWINSZ' fails (strangely only for telnet sessions,
+	not rlogin sessions), ignore its errno == EINVAL and try to get
+	the number of columns another way.
+
+	* stty.c (set_window_size): If ioctl to get window size fails,
+	(as on telnet sessions to Solaris 2.[12] systems) try to set the
+	requested fields anyway, setting to zero any unspecified fields.
+	This is what Sun's /bin/stty appears to do.
+	* (display_window_size): Don't display anything for the number
+	of rows and columns if the ioctl call intended to get them fails.
+
+Tue Nov 30 23:58:54 1993  Jim Meyering  (meyering@comco.com)
+
+	* Version 1.9.2.
+
+Mon Nov 29 00:28:35 1993  Jim Meyering  (meyering@comco.com)
+
+	* stty.c, configure.in, acconfig.h: Revert change of Nov 26.
+	I am no longer able to reproduce the behavior that prompted
+	that patch -- but I had tested only using an old version of gcc.
+	When building with a more recent version of gcc or with /bin/cc
+	there is no problem.
+
+Sat Nov 27 15:11:21 1993  Jim Meyering  (meyering@comco.com)
+
+	* nice.c (main): If an adjustment is specified, but no command is
+	given, give a diagnostic in addition to the usage message.
+	(isinteger): Accept a leading `+'.
+
+Fri Nov 26 18:49:42 1993  Jim Meyering  (meyering@comco.com)
+
+	* stty.c [GWINSZ_BROKEN]: Define TIOCGWINSZ to TCGETS for Solaris-2.2.
+	On that system, ioctl (0, TIOCGWINSZ, &win) always fails, but using
+	TCGETS works.  Reported by Francois Pinard.
+
+	* configure.in [GWINSZ_BROKEN]: New test to detect Solaris' inability
+	to get window size from ioctl using TIOCGWINSZ.
+	* acconfig.h [GWINSZ_BROKEN]: Add an #undef.
+
+Mon Nov 22 23:40:21 1993  Jim Meyering  (meyering@comco.com)
+
+	* who.c [defined (UTMPX_FILE)]: (undef and) define UTMP_FILE to
+	this value even if UTMP_FILE is already defined.  Because some
+	systems define both symbols.  From Arne H. Juul.
+	* [MESG_BIT]: Rename to S_IWGRP (from sys/stat.h>) and define only
+	if not already defined.
+
+Fri Nov 19 23:08:03 1993  Jim Meyering  (meyering@comco.com)
+
+	* who.c (print_entry): Produce reasonably formatted output even when
+	sizeof (this->ut_name,ut_line) are much larger than 8.  For Solaris
+	and other SysVr4.  With help from Arne H. Juul.
+	* configure.in (HAVE_UTMPX_H): New test; combined with test for the
+	ut_host field.  From Arne H. Juul.
+
+	* memcmp.c: New file.
+	* lib/Makefile.in [SOURCES]: Add memcmp.c.
+	* configure.in (AC_REPLACE_FUNCS): Add memcmp.
+	Add test for 8-bit clean memcmp.
+
+	* configure.in (AC_HAVE_FUNCS): Add isascii.
+	* expr.c [!defined (isascii) || defined (STDC_HEADERS)]: This failed
+	on AIX PS/2 1.3 systems because isascii is a function and it is used
+	in definitions (with the necessary side effect of assigning to a
+	global variable) of the is* macros.  Also test HAVE_ISASCII and
+	redefine ISASCII(c) instead of isascii.
+	Reported by Minh Tran-Le (tranle@intellicorp.com).
+	* printf.c: Ditto.
+
+	* configure.in (AC_HAVE_HEADERS): Add sys/timeb.h; getdate.y tests
+	HAVE_SYS_TIMEB_H.
+
+	* stty.c (main): Detect the case in which POSIX-conformant tcsetattr
+	fails and still returns zero.
+
+Wed Nov 17 21:05:10 1993  Jim Meyering  (meyering@comco.com)
+
+	* yes.c (main): Complete my half-finished Nov 2 change.
+	yes with arguments did not print newlines.  From Andreas Schwab
+	(ls5.informatik.uni-dortmund.de).
+
+	* stty.c (wrapf): Fix off-by-one error that could make `stty -a'
+	output lines one character too long.  From Andreas Schwab.
+
+Sat Nov 13 00:11:19 1993  Jim Meyering  (meyering@comco.com)
+
+	* Version 1.9.1.
+
+	* configure.in [LIBS]: Add -lbsd if that is necessary to get the
+	syslog function.  With help from Kaveh Ghazi.
+
+	* configure.in [LIBS]: Reorganize/unify the code that adds libraries
+	solely to resolve syslog.  Add a library only if it is required to
+	resolve the syslog reference.
+
+	* configure.in [AC_HAVE_HEADERS]: Check for sys/timeb.h.
+	getdate.y needs to know.
+	[LIBS]: Check for initgroups in -los.  This is required by SCO-ODT-3.0
+	when linking su.
+	[LIBS]: Check -lufc for crypt.
+	Reported by Steven W Orr (steveo@world.std.com).
+
+Thu Nov 11 23:55:48 1993  Jim Meyering  (meyering@comco.com)
+
+	* id.c [NGROUPS_MAX]: Undefine before redefining.
+	From Kaveh R. Ghazi (ghazi@noc.rutgers.edu).
+
+	* who.c (list_entries): Trim any trailing blanks from ut_name
+	and make sure the string is NUL-terminated before printing it.
+	Before, `who -q' displayed 8-character names with a tty
+	(e.g. `q1') suffix.
+
+	* stty.c [CFLUSHO]: Move this definition so it follows the
+	one for VFLUSHO.
+
+Mon Nov 08 23:16:36 1993  Jim Meyering  (meyering@comco.com)
+
+	* Version 1.9.
+
+	* su.c (correct_password): Report an error and fail if getpass
+	returns NULL.
+
+Tue Nov 02 01:14:21 1993  Jim Meyering  (meyering@comco.com)
+
+	* acconfig.h: Add comments.
+
+	* printenv.c (main): Exit with status == 2 for file error.
+
+	* yes.c (main): Restore argv/optind handling -- now that
+	parse_long_options doesn't change optind.
+
+Mon Oct 25 19:22:58 1993  Jim Meyering  (meyering@comco.com)
+
+	* basename.c, date.c, dirname.c, echo.c, env.c, expr.c, id.c,
+	logname.c, nice.c, pathchk.c, printenv.c, printf.c, sleep.c,
+	stty.c, su.c, tee.c, test.c, tty.c, uname.c, who.c, whoami.c,
+	yes.c: Use the preferred `--longopt=arg' syntax in --help message
+	rather than `--longopt arg'.  From Francois Pinard.
+
+	* stty.c (main, integer_arg): Don't just call error(1,... about
+	improper usage.  Call `error (0,...' then usage (1).
+
+Sun Oct 24 14:10:23 1993  Jim Meyering  (meyering@comco.com)
+
+	* test.c [member]: Don't try to cast index return value to an int.
+	That can lose on systems with 64-bit pointers.
+
+	* long-options.c: Save and restore optind, too.
+	* long-options.h: New file.
+	* long-options.c, echo.c, expr.c, printf.c, test.c, yes.c:
+	Include it instead of duplicating dcls.
+	* src/Makefile.in: Add dependencies for it.
+
+Tue Oct 19 00:26:27 1993  Jim Meyering  (meyering@comco.com)
+
+	* expr.c [!__STDC__]: Don't define away `const'.  configure alone
+	decides whether to do that.  From Francois Pinard.
+
+Sat Oct 16 22:32:54 1993  Jim Meyering  (meyering@comco.com)
+
+	* whoami.c (main): Cast printf arg UID so it matches the type
+	expected by %u format no matter how uid_t is defined.
+
+	* stty.c: Accept `status' option and VDISCARD as an alias for
+	VFLUSHO.  From Arne H. Juul (arnej@imf.unit.no).

+	su.c, tee.c, test.c, true.sh, tty.c, uname.c, who.c, whoami.c,
+	yes.c: Using --help gets long well- formatted help.  Now --help
+	writes to stdout and exits successfully.  From Francois Pinard
+	<pinard@iro.umontreal.ca>.
+
+Wed Oct 13 13:10:27 1993  Jim Meyering  (meyering@comco.com)
+
+	* long-options.c: Include sys/types before system.h.
+	From Franc,ois Pinard (pinard@iro.umontreal.ca).
+
+Tue Oct 12 00:53:26 1993  Jim Meyering  (meyering@comco.com)
+
+	* stime.c [HAVE_CONFIG_H, CONFIG_BROKETS]: Include <config.h>
+	or "config.h".
+
+	* src/Makefile.in [clean]: Also delete '['.
+
+Sun Oct 10 14:05:23 1993  Jim Meyering  meyering@comco.com
+
+	* false.sh, groups.sh, nohup.sh, true.sh: Add --help and --version.
+	* src/Makefile.in (false, groups, nohup, true): Substitute the string

+
+Sat Oct  9 23:12:53 1993  Jim Meyering  meyering@comco.com
+
+	* configure.in: Remove AC_UNISTD_H; add unistd.h to AC_HAVE_HEADERS.
+
+Tue Oct  5 22:18:05 1993  Jim Meyering  meyering@comco.com
+
+	* tty.c (main): Detect write error.  Use isatty (rather than
+	testing whether ttyname() is NULL) to determine exit status
+	because ttyname may return NULL when stdin is a terminal device.
+
+	* expr.c (eval7): Rewrite if-else-if-else... sequence to avoid a
+	spurious `function returns without a value' warning.
+
+	* printenv.c (main), tty.c (main): Detect and report write errors.
+
+	* echo.c, patchchk.c, printenv.c, printf.c, sleep.c, stty.c, su.c,
+	tee.c, test.c, tty.c, uname.c, yes.c: Accept --help and --version

+
+	* configure.in: Add AC_TIME_WITH_SYS_TIME and AC_STAT_MACROS_BROKEN.
+
+	* nice.c (main) [NICE_PRIORITY]: When given an argument, don't
+	try to get current priority.  nice() requires only the delta;
+	we don't need to compute the absolute priority as for setpriority.
+
+Mon Oct 04 22:15:07 1993  Jim Meyering (meyering@comco.com)
+
+	* who.c (print_entry, print_heading, who_am_i):
+	Cast printf field width arguments to int to avoid warnings.

+	const.
+
+Wed Sep 08 00:07:36 1993  Jim Meyering (meyering@comco.com)
+
+	* test.c [advance, unary_advance]: Rewrite using do{...}while(0)
+	paradigm instead of comma expressions that make Alpha OSFv1.3
+	C compiler segfault.
+
+	* basename.c, date.c, dirname.c, env.c, id.c, logname.c, nice.c:
+	Add --help and --version options.
+
+Sat Jul 24 08:52:18 1993  Jim Meyering (meyering@comco.com)
+
+	* configure.in: Check for -lshadow.  Linux needs it when using shadow

+
+	* configure.in: Add AC_GETGROUPS_T.
+	* id.c, test.c: Don't define GETGROUPS_T.  Now configure does it.
+
+Sun May  2 00:21:05 1993  Jim Meyering  (meyering@comco.com)
+
+	* expr.c (eval6): Terminate result with a zero byte.
+	The command `expr substr xx 1 2' would fail on systems with
+	tight malloc.  From Steve James <smj@cats.COM>.
+
+	* expr.c (null): Recognize the string `0' as zero.
+	(divide, mod): Upon request to divide by zero, give an error
+	message instead of dumping core.
+	From J.T. Conklin <jtc@wimsey.com>.
+
+	* configure.in: Check for sys/time.h; getdate.y needs it for
+	structs timeval and timezone on some systems.
+	* Check for gettimeofday and for `struct tm'.
+	* Add existence tests for memcpy and bcopy.
+
+	* configure.in: Find a parser generator.
+
+	* putenv.c: Include stdlib.h only if __GNU_LIBRARY__ is defined.
+	Many vendor-supplied <stdlib.h> have a declaration of putenv that
+	conflicts with ours.
+
+Tue Apr 20 02:33:24 1993  David J. MacKenzie  (djm@kropotkin.gnu.ai.mit.edu)
+
+	* stty.c: Use GWINSZ_IN_SYS_IOCTL, not _AIX, to determine

+
+	* env.c, id.c, nice.c, pathchk.c, stty.c, su.c, tee.c, tty.c,

+	and optional_argument.
+
+Tue Nov 24 09:46:02 1992  David J. MacKenzie  (djm@goldman.gnu.ai.mit.edu)
+
+	* echo.c: Use V9_DEFAULT instead of USG.  Define it always.

+
+Wed Nov 11 18:19:10 1992  Jim Meyering  (meyering@hal.gnu.ai.mit.edu)
+
+	* All files in src: Make all functions and extern variables static.
+	Make all longopts arrays const as well as static.
