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.

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.

	* 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.

	* 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).

	* basename.c, date.c, dirname.c, echo.c, env.c, expr.c,
	false.sh, groups.sh, id.c, logname.c, long-options.c, nice.c,

	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.

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.

	* 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.

	* who.c (print_entry, print_heading, who_am_i):
	Cast printf field width arguments to int to avoid warnings.
	(idle_string): Cast idle seconds and minutes to int.

	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)

	* mkinstalldirs: New file.
	* Makefile.in (installdirs): Use it.

Thu May 13 01:03:16 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>.

	(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

	* stty.c: Use GWINSZ_IN_SYS_IOCTL, not _AIX, to determine
