	Combine nearly identical -a and -v cases.
	Close input files.

Fri Oct  6 23:10:01 1995  Jim Meyering  (meyering@comco.com)

	* join.c (main): Report `too few/many non-option arguments'
	then print --help output rather than just the latter.
	Properly interpret obsolescent usage like `join -o 2.1 2.1 2.2'.
	(usage): Describe POSIX -1, -2 options and deprecate -j* ones

	* join.c (usage): Move to precede all other functions.

	* join.c: Protoize.

Tue Oct  3 22:44:05 1995  Jim Meyering  (meyering@comco.com)

	Reported by Paul Nevai <nevai@ops.mps.ohio-state.edu>.
	Fix suggested by Karl Berry.

	* md5sum.c (main): Declare counter, N_STRINGS, to be an integral

	* man/Makefile.in (install-data, uninstall): Use sed not basename.
 	The GNU Coding Standard suggests that only a select set of
 	relatively standard utilities be used in Makefiles.  basename is
	not among them.  Suggested by Ulrich Drepper.

Sun Sep 24 08:36:47 1995  Jim Meyering  (meyering@comco.com)

	* cksum.c: Protoize.
	* cut.c: Protoize.

	* src/Makefile.in (OBJECTS): Reflect that cksum.c and cut.c use

	* lib/Makfile.in: (GETOPT, MEMCHR, REGEX): New variables.
	(OBJECTS): Use them instead of hardcoding object file names.
	Suggested by Ulrich Drepper.

	* md5sum.c (md5_check): Distinguish between open/read failure
	and checksum mismatch.

Mon Sep 18 23:15:05 1995  Jim Meyering  (meyering@comco.com)

	* md5sum.c: Protoize.

	Rename --verbose to --warn, --quiet to --status.
	(main): Handle --help and --version using parse_long_options.
	(md5_check): Check ferror.

	* sort.c (tempname): Replace `16' with a more readable expansion.

	(checkfp): Rearrange loop to avoid duplicate test.
	Move a couple dcls from function scope into inner block.

Tue Aug  8 21:49:27 1995  Jim Meyering  (meyering@comco.com)

	* md5sum.c (main): Fail if either --verbose or --quiet is specified
	when not verifying checksums.

	* md5sum.c (md5_check): Fail if no valid line is found.
	Don't use the word `fail' unless there were failures --
	instead, say `all N tests passed.'

	* md5sum.c (main) [handling --string option]: Don't output
	nonstandard `b' binary flag.  From Greg Troxel (gdt@bbn.com).
	* md5-test.rfc: Remove now-inconsistant `b' marker.
	(usage): Clarify help message.  With suggestions from Greg Troxel.

Mon Aug  7 23:27:54 1995  Jim Meyering  (meyering@comco.com)

	* sort.c (mergefps) [lint]: Initialize SAVEALLOC to avoid spurious
	compiler warning.  From Ulrich Drepper.

	From Franc,ois.

Mon Aug  7 00:02:59 1995  Jim Meyering  (meyering@comco.com)

	* system.h (_): Define macro -- as empty for now.
	* src/*.c: Annotate localizable strings with _(...).  From Franc,ois.

Sat Aug  5 23:51:25 1995  Jim Meyering  (meyering@comco.com)

	* Version 1.12.1.

	* configure.in: Add fp_C_PROTOTYPES.

Fri Aug  4 23:21:46 1995  Jim Meyering  (meyering@comco.com)

	* src/Makefile.in (DISTFILES): Include ansi2knr.c and ansi2knr.1.
	Add suffixes, dependencies, and rules to convert ANSI source to K&R
	when required.  Mark tr.o and comm.o as the only such files (for now).

	* tr.c: Protoize.
	* comm.c: Protoize.

	* Makefile.in (DISTFILES): Add aclocal.m4 and acconfig.h.
	(configure): Depend on aclocal.m4.
	(stamp.h.in): Depend on aclocal.m4 and acconfig.h.

Sun Jul 30 00:01:58 1995  Jim Meyering  (meyering@comco.com)

	* md5sum.c (md5_check): Use getline instead of fgets.

	* lib/Makefile.in: (SOURCES): Add getline.c.
	(OBJECTS): Add getline.o.
	(DISTFILES): Add getline.h.
	(getline.o): Depend on getline.h.

	* md5.c [memcpy]: Define to bcopy if needed.
	(md5_buffer): Explicitely cast SWAP expressions to unsigned
	to avoid warning.

	* lib/Makefile.in (strtoul.o): Depend on strtol.c.

	* sort.c (check): Print `disorder on...' message on standard error,
	not stdout.  This is a minor concession to POSIX which says
	`no output shall be produced...'.

	* sort.c (main): Fix -k so it works. -k 2,3 was being treated
	like -k 2.  Reported by Marcus Daniels <marcus@sysc.pdx.edu>.

Wed Jul 26 22:54:48 1995  Jim Meyering  (meyering@comco.com)

	* man/Makefile.in (install, uninstall): Strip off `.1', not just `1'
	before applying $(transform) to manual name.  From Karl Berry.

	* md5sum.c (have_read_stdin): New global variable.
	(md5_file, md5_check): Set it.
	(main): Use it.

	* md5sum.c [OPENOPTS]: Depend explicitly on BINARY.
	(md5_file): Take a new parameter, MD5_RESULT, and no longer
	generate output.
	(md5_check): Invoke md5_file instead of calling fopen directly.
	When giving a diagnostic for a line with invalid format, also report
	the line number.
	(main): Generate output after a successful md5_file call.
	[in many places]: Upon detection of an error, rather than exiting
	immediately, issue a diagnostic, note that an error occurred and
	exit later.

Mon Jul 24 21:48:26 1995  Jim Meyering  (meyering@comco.com)

	* tail.c (tail_bytes) [from_start]: For regular files, seek
	relative to the initial input file pointer position, not
	necessarily from the beginning of the file.
	[!from_start]: Don't back up past the initial position of the
	input file pointer.
	(tail_lines): Call file_lines only if FD refers to a regular file
	with its file pointer positioned at beginning of file.  Otherwise,
	call pipe_lines.  This is a kludge.  Once there's a decent test
	suite, fix this properly.
	Before, (echo 1; echo 2) > k; sh -c 'read x; tail' < k
	would output both lines of the input file even though the first had
	already been read.  Reported by John Roll (john@panic.harvard.edu).

	* md5sum.c [_LIBC || STDC_HEADERS] (TOLOWER): Define to tolower.

	* csplit.c (main): When too few arguments are given, don't just
	issue the usage message; also report why.

Sat Jul 22 00:16:01 1995  Jim Meyering  (meyering@comco.com)

	* md5sum.c (md5_check): New function -- extracted from main.

Fri Jul 21 01:21:49 1995  Jim Meyering  (meyering@comco.com)

	* md5sum.c (md5_file): New function -- extracted from main.
	(main): Call the new function instead of doing all that in an
	if-stmt. Always use "%s" format rather than raw filename as
	format argument in printf-style functions like error.  Otherwise,
	filenames containing `%' are likely to lose.
	Remove all mention of `old format'.
	(split_3): No longer parse the `new format.'  There is only one
	valid format now: the compatible one.

	* lib/Makefile.in: (SOURCES): Add md5.c.
	(OBJECTS): Add md5.o.
	(DISTFILES): Add md5.h.
	(md5.o): Depend on md5.h.

	* system.h [!EXIT_FAILURE, !EXIT_SUCCESS]: Define them.
	* lib/md5.c (md5_stream): Check for read failure and return
	indication of success rather than second argument.
	* lib/md5.h (md5_stream): Update prototype.
	[__P]: Define macro.
	* md5sum.c: Use EXIT_FAILURE and EXIT_SUCCESS.
	(main): Report an error if md5_stream fails.  Otherwise, running
	`md5sum dir-on-mounted-filesystem' always reported the checksum
	for an empty file.  Now it gets the `is a directory' error.
	Greg McGary (gkm@magilla.cichlid.com) reported that the released
	version got stuck in an infinite loop with such arguments.

	* lib/md5.c: New file.
	* lib/md5.h: New file.
	* md5sum.c: Rewritten to use library interface.
	From Ulrich Drepper.

Sun Jul 16 18:42:34 1995  Jim Meyering  (meyering@comco.com)

	* configure.in: Add AC_C_INLINE: md5sum.c uses inline keyword.

Tue Jul 11 21:56:02 1995  Jim Meyering  (meyering@comco.com)

	* md5sum.c Add #else block after #ifdef VMS.
	(main): Rename local variable.
	Add FIXME: allow newlines in filenames.
	Detect and report failed fclose calls on stdout and checkfile_stream.

	* tr.c (unqote): Comment out unreachable break stmts.
	(append_range): Declare FIRST and LAST parameters to be unsigned int,
	not size_t.
	(find_closing_delim): Clean up interface, separating boolean success
	indicator and index.
	(find_bracketed_repeat): Likewise.
	(build_spec_list): Adapt to use new interfaces.
	Declare CLOSING_DELIM_IDX and CLOSING_BRACKET_IDX to be of
	type size_t, not int.
	(main): Declare NR and CHARS_READ to be of type long, not int.

	* sort.c (main): Comment out unreachable break stmt.

	* tail.c (tail): Explicitly cast to long the N_UNITS argumennt in
	call to tail_lines.  Otherwise, NetBSD lost because N_UNITS (of type
	off_t, a 64-bit type on NetBSD) wasn't converted to the target type,
	long.  Reported by Dan Hagerty (hag@gnu.ai.it.edu).

	* comm.c: Reorder functions so main is last, so no forward dcls
	are needed.

Sun Jul  9 11:41:15 1995  Jim Meyering  (meyering@comco.com)

	* sort.c (main): When using obsolescent +pos -pos syntax, allow
	omission of field spec only when character offset is specified.
	Otherwise, -. +. would be accepted.

Sat Jul  8 13:48:06 1995  Jim Meyering  (meyering@comco.com)

	* sort.c (main): Allow field spec, M, to be omitted in +M.N or -M.N
	position specification.  For compatibility with existing practice
	(what vendors?), omitting M is now equivalent to specifying `0' for M,
	but only when using the +pos -pos syntax, not with the -k option.
	From Rick Sladkey (jrs@world.std.com).

Thu Jul  6 23:44:20 1995  Jim Meyering  (meyering@comco.com)

	* od.c (dump): Correct loop-termination criterion.
	Before, running `printf 1234| ./od --width=4 --read-bytes=4'
	printed output for 8 bytes -- the last four were garbage.
 	This happened only when the dump limit, N, was specified (with
	--read-bytes=N) and N was a multiple of bytes_per_block
	(usually 16, but 4 in this example).  From Andreas Schwab.

Sun Jul  2 22:12:40 1995  Jim Meyering  (meyering@comco.com)

	* lib/Makefile.in (check): Depend on libtu.a.

	* md5sum.c (split_3): Rewrite to parse Plumb/Lankester format as well.
	(main): Print each sum line in (de facto) standard Plumb/Lankester
	format.
	New option: --quiet.
	Check option no longer takes an argument.
	When checking, exit status reflects success.

Sat Jun 24 16:18:01 1995  Jim Meyering  (meyering@comco.com)

	* md5sum.c [__GNUC__]: Don't conditionalize use of "inline".
	Autoconf (via config.h) defines it away for compilers that don't
	grok it.

	* cat.c, comm.c, join.c, sort.c, uniq.c: Undefine min/max before
	defining to avoid redefinition warning on some systems.

	* csplit.c (read_input): Rename paramater MAX to MAX_N_BYTES.
	This avoids potential conflict with max macro from some system's
	header files when using bad pre-ANSI compilers.

	* uniq.c (usage): Fix typo in text of --help output.
	From Steve McConnel <steve@acadcomp.sil.org>

	* md5sum.c [uint32]: When testing for 32-bit arithmetic type,
	also check `unsigned long', as a concession to systems with
	int's smaller than 32 bits.

	* configure.in (AC_REPLACE_FUNCS): Remove memcmp (again!) since
	AC_FUNC_MEMCMP already handles it.  This avoids warnings from
	ranlib on nextstep systems.  From Kaveh Ghazi.

	* csplit.c (interrupt_handler): Declare to have a single integer
	parameter.  Otherwise, some compilers fail with a type mismatch
	error in sa_handler assignment.

	* fmt.c [word]: Redefine.  Otherwise, systems (Unicos for one) with
	headers that typedef `word' get syntax errors because of the
	variable by the same name.

	* join.c [join]: Redefine to avoid conflict with prototype in some
	system header file.  Also for Unicos.

	* md5sum.c (main): Remove spurious colon in getopt spec string.
	From Ken Pizzini <kenp@spry.com>.

Tue Jun 20 06:59:16 1995  Jim Meyering  (meyering@comco.com)

	* md5sum.c (md5_file): Initialize two elements of LEN portably,
	rather than with ANSI aggregate initialization.  Reported by
	Edzer Pebesma <Edzer.Pebesma@rivm.nl>.

Sun Jun 18 09:15:57 1995  Jim Meyering  (meyering@comco.com)

	* Version 1.12.

	* md5sum.c (process_buffer): Copy values from struct into
	individual local variables before performing computation on them,
	then copy results back into returned struct.  Solely for better
	optimization by compilers that can't keep struct members in
	registers.  From Ulrich Drepper.

Thu Jun 15 22:09:14 1995  Jim Meyering  (meyering@comco.com)

	* md5sum.c: Remove unnecessary uses of `defined' in #if* tests.
	Don't use #elif.  Some older compilers don't grok it.
	(split_3): New function to parse out sum, flag, and filename
	when reading check file.
	(hex_digits): Remove length parameter since string parameter is
	now nul-terminated.
	(main): Don't allocate separate arrays for filename and sum
	when checking.  Get pointers into line buffer with split_3 instead
	of using sscanf.
	(main): Treat `no file args' just like `-' when not checking
	or using strings.
	(hex_digits): Unprotoize.

	* md5sum.c (main): Don't use a separate loop to convert to lower
	case.  Suggested by Ulrich Drepper.
	(CLOSE): New macro.
	(md5_file): Use it.
	From Ulrich Drepper.

	* md5sum.c: Don't include values.h.
	[__P]: Undefine it.

	* md5sum.c: [UNIX || unix]: Also test __UNIX__, __unix__,
	and _POSIX_VERSION.  Reported by Arne H. Juul.

Tue Jun 13 21:20:10 1995  Jim Meyering  (meyering@comco.com)

	* tr.c [NDEBUG]: Define it to disable assertions.  Some systems
	have a broken <assert.h> header.
	(is_char_class_member): Set a variable in each branch of switch
	stmt and return that value after the switch (rather than returning
	directly from every branch).
	(unquote): More int->size_t changes.
	(build_spec_list): More int->size_t changes.
	Be very careful about comparison now that variables are unsigned:
	Use i + 2 < len rather than i < len - 2.  The latter didn't work
	for len < 2.  Caught early thanks to a thorough regression test
	suite.

Mon Jun 12 23:07:59 1995  Jim Meyering  (meyering@comco.com)

	* sort.c (xfclose): Don't try to flush stdin, only stdout.
	Otherwise, at least Ultrix-4.3's fflush would return EOF.
	Reported by Jim Blandy (jimb@cyclic.com).

	* tr.c (non_neg_strtol): Don't compare signed and unsigned.
	[struct Spec_list] (indefinite_repeat_element): New member.
	Use size_t rather than int or unsigned long where reasonable.
	(get_spec_status): Make interface cleaner.
	(get_s1_spec_status): New function.
	(get_s2_spec_status): New function.
	(validate): Use new functions instead of get_spec_status.

Sun Jun 11 00:39:50 1995  Jim Meyering  (meyering@comco.com)

	* md5sum.c: New file.  From Ulrich Drepper.
	* md5-test.rfc: New file.

	(DISTFILES): Add md5-test.rfc.

	* tr.c (look_up_char_class, append_char_class, append_equiv_class):
	Use const attribute when appropriate.

Sun May 28 14:48:58 1995  Jim Meyering  (meyering@comco.com)

	* join.c: Overhauled to make -a1 and -a2 options work.
	Passed all tests in a fairly thorough test suite.
	Reported by Michael Hasselberg (mikelh@zonta.ping.de).

Sat May 27 00:35:47 1995  Jim Meyering  (meyering@comco.com)

	* tail.c (main): Remove dcl of and statements that set now-unused
	variable.

	* system.h [!STDC_HEADERS && HAVE_MEMORY_H]: Include memory.h.
	Without this, SunOS doesn't get type for memchr.
	Reported by Kaveh Ghazi.

Thu May 25 00:06:50 1995  Jim Meyering  (meyering@comco.com)

	* tail.c (tail_lines): Change one more `long' to `off_t'.
	Otherwise, tail didn't work on NetBSD.  From Arne H. Juul.

	* csplit.c [struct control]: Change type of `repeat' to unsigned
	long to avoid conversion warning.

Sun May 21 07:50:00 1995  Jim Meyering  (meyering@comco.com)

	* Makefile.in (.PHONY): TAGS is not a phony target.  From Franc,ois.

	* xstrtol.c (__strtol): Remove prototype altogether.
	Move inclusion of xstrtol.h back so that it follows system headers.

	* Version 1.11.2.

Sat May 20 06:44:14 1995  Jim Meyering  (meyering@comco.com)

	* join.c (ADD_FIELD): Declare in K&R style, not ANSI.
	From Kaveh Ghazi.

	* xstrtol.c: Define NDEBUG for systems with losing assert.h.
	(__strtol): Add __unsigned to prototype and use __P.
	Move inclusion of xstrtol.h to precede prototype.
	From Kaveh Ghazi.

	* memmove.c: Include config.h for definition of const.
	From Kaveh Ghazi.

	* All Makefile.in (install-exec, install-exec): New targets.
	From Karl Berry.

	* tr.c (look_up_char_class): Take a string length argument -- required
	because the argument is a string that is *not* NUL-terminated.
	Use strncmp, not strcmp and add string lengths comparison.
	(append_char_class): Update caller.  Before this change,
	tr '[:upper:]' '[:lower:]' read one uninitialized byte.
	From Andreas Schwab.

	* split.c (next_file_name): Move dcls of file-scope variables into
	this function.  Don't rely on arithmetic being two's complement.

	* paste.c [CLOSED, ENDLIST]: Don't cast constants to FILE pointers.
	Instead, declare two FILE structs and use their addresses.

	* csplit.c (record_line_starts): Remove set-but-not-used,
	file-scope variable.

Sat May 13 08:57:20 1995  Jim Meyering  (meyering@comco.com)

	* all source files (usage): Include one- or two-line synopsis
	in --help output.  From Karl Berry.

	* lib/Makefile.in [.c.o]: Remove -I. since safe-l?stat.h are no
	longer used.

	per GNU Standards.

Thu May  4 23:15:58 1995  Jim Meyering  (meyering@comco.com)

Thu Apr 13 23:22:57 1995  Jim Meyering  (meyering@comco.com)

	* head.c: Remove block of redundant comments describing options.
	(usage): Remove reference to -l option.  It's not valid.

	(get_lcm): Likewise.
	(dump_strings): Likewise.
	(main): Likewise.
	(dump): Cast BYTES_PER_BLOCK to off_t in MIN expression.
	(dump_strings): Declare bufsize to be of type size_t, not int.

	* split.c (next_file_name): Don't reuse X as an index.

	* wc.c (wc): Don't overcount the number of bytes when reading
	from a regular file on stdin with file pointer not at BOF.
	From Karl Heuer <karl@gnu.ai.mit.edu>.  Before, the command
	`(dd ibs=99k skip=1; wc -c) < /etc/group' made wc wrongly output
	the size of the file.  Now it outputs `0'.

Sat Jan 28 07:07:23 1995  Jim Meyering  (meyering@comco.com)

	* cat.c (cat): Use memmove rather than bcopy.

	not bcopy.
	(AC_CHECK_FUNCS): Add strchr and strrchr.

Tue Jan 24 22:18:19 1995  Jim Meyering  (meyering@comco.com)

	* fmt.c (copy_rest): Replace `||' with `&&'.  Before, a paragraph
	not followed by a newline would be followed by data copied from
	uninitialized storage.  Repeat by `printf abc|fmt|od -ac'.
	Reported by Franc,ois Pinard.

	* od.c: Rename macros with FP_ prefix.  Use FLOAT_ instead.
	AIX-2.2.1 declares a typedef, FP_DOUBLE, that conflicted.
	Be careful to use off_t instead of explicit `unsigned long'.
	Otherwise, systems like 4.4BSD lose on calls to fseek that
	expect off_t (which is long long on that system).
	(parse_old_offset): Use xstrtoul
	(main): Likewise.

	* src/Makefile.in (od.o, tail.o): Depend on ../lib/strtol.h.

Mon Dec 19 22:13:55 1994  Jim Meyering  (meyering@comco.com)

	* tail.c (numerous functions): Give char* filename arguments the
	const attribute.

	* lib/Makefile.in (SOURCES): Remove xwrite.c.  It was no longer used.

	(distclean): Remove references to safe-l?stat.c.
	Remove all related rules and dependencies.

	* src/Makefile.in: $(OBJECTS): Depend on ../lib/error.h.

	* tail.c (tail_file): Fix call to error with %s in format, but
	no corresponding argument.

	* src/*.c: Include "error.h" instead of simply declaring
	`void error ();'.
	* od.c (main): Use %lu, not %d for unsigned long.
	(my_strtoul, uint_fatal_error): Remove functions.  Use xstrtoul
	and STRTOL_FATAL_ERROR instead.

Sun Dec 11 17:24:09 1994  Jim Meyering  (meyering@comco.com)

	* sort.c (main): Fix interpretation of field offsets when specified
	via -k option.  They were being interpreted as zero-indexed.  POSIX
	says they are 1-based indices.  From Rik Faith <faith@cs.unc.edu>.
	(keycompare): Don't ignore characters at the end of words when
	otherwise they would compare equal.  From Rik Faith.

	* tail.c (<most functions>): Change the type of n_units/n_lines/n_bytes
	to off_t because n_bytes is used as the option to fseek and off_t may
	be long long (e.g. on BSD4.4).  The only place where a 32-bit limit is
	imposed is in the string-to-integer converstion of xstrtol.
	(main): Use xstrtol instead of manual string to integer conversion.

	* csplit.c (get_format_width, get_format_prec): Use ISDIGIT instead of
	comparisons against '0' and '9'.

	* tr.c [!ULONGMAX]: Define it.
	[!LONGMAX]: Define in terms of ULONGMAX instead of as a 32-bit constant.

	* full-write.c: Declare (or not) errno based on definedness or
	errno, not STDC_HEADERS.
	* safe-read.c: Likewise.
	* xwrite.c: Likewise.

Thu Nov 17 06:37:33 1994  Jim Meyering  (meyering@comco.com)

	* tail.c (dump_remainder): Flush standard output just before
	sleeping so that `tail -f' will output partial lines sooner.
	This applies only when following the end of a single file.
	From Leonard N. Zubkoff <lnz@dandelion.com>.

	* tail.c (file_lines, pipe_lines, pipe_bytes, start_bytes,
	start_lines, dump_remainder): Use STDOUT_FILENO instead of `1' in
	XWRITE calls.
	* tac.c (output): Use STDOUT_FILENO instead of `1' in xwrite call.
	* system.h (STDIN_FILENO, STDOUT_FILENO, STDERR_FILENO): Define if
	not already defined.

Wed Nov 16 07:01:38 1994  Jim Meyering  (meyering@comco.com)

	* tr.c: Include <getopt.h> instead of "getopt.h".

	* sort.c (tempname): Merge two very similar sprintf stmts into one.

	* tail.c: Use BUFSIZ instead of BUFSIZE.

	* cut.c: Declare DELIM to be `int' rather than unsigned char.

	* fmt.c: Use index, not strchr -- per GNU Standards.
	Reported by Kaveh Ghazi.
	Always include <config.h>.
	(main): Include program name in --version output.

Sun Nov 06 00:17:21 1994  Jim Meyering  (meyering@comco.com)

	* Version 1.11.

Sat Nov 05 15:14:44 1994  Jim Meyering  (meyering@comco.com)

	* memcmp.c, srtoul.c: Use up-to-date versions.
	Reported by Franc,ois Pinard.

	* src/Makefile.in (DEFS): Remove -Dlint... again.

	* src/Makefile.in (PROGS): Add fmt!
	Reported by Andreas Stolcke (stolcke@ICSI.Berkeley.EDU).

Fri Nov 04 17:26:16 1994  Jim Meyering  (meyering@comco.com)

	* Version 1.10.

Thu Nov 03 23:23:08 1994  Jim Meyering  (meyering@comco.com)

	* linebuffer.h: Use __P instead of _P since the latter conflicts
	with a definition in some <ctype.h>.  From Kaveh Ghazi.

Wed Nov 02 17:36:34 1994  Jim Meyering  (meyering@comco.com)

	* tr.c: Add const attribute where appropriate.

	* tail.c (BUFSIZ): Use definition from <stdio.h>.

Tue Nov 01 23:54:09 1994  Jim Meyering  (meyering@comco.com)

	* tail.c (XWRITE): Allow n_bytes == 0 but call fwrite only if
	n_bytes is positive.  Turn off assertions.  `tail /dev/null' was
	getting a failed assertion.  Reported by Doug McLaren
	(dougmc@comco.com).

	* cut.c (cut_bytes): Print at least a newline for every line of input.
	(cut_fields): Print a newline even for lines whose only selected
	field is empty.  But print nothing when using -s without -f1.
	And print nothing for empty input.  Reported by
	Richard_Sharman@software.mitel.com.

Tue Nov 01 06:05:23 1994  Jim Meyering  (meyering@comco.com)

	* fmt.c: Change #ifdef __STDC__ to #if defined (__STDC__) && __STDC__.
	* linebuffer.h: Likewise.

Mon Oct 31 06:53:32 1994  Jim Meyering  (meyering@comco.com)

	* configure.in (AC_REPLACE_FUNCS): Remove memcmp since AC_FUNC_MEMCMP
	already handles it.  From Kaveh Ghazi.

	* {lib,src}/Makefile.in (DEFS): Don't use -Dlint.  Some systems
	get failures when it's defined.  From Kaveh Ghazi.

	* cat.c (cat): Conditionalize test for errno == ENOSYS.  It's not
	defined on some Next and Alliant systems.  From Kaveh Ghazi.

	* sort.c join.c (main): Include version.h and call parse_long_options
	with the proper number of arguments.  Reported by Franc,ois Pinard.

Sun Oct 30 01:30:41 1994  Jim Meyering  (meyering@comco.com)

	* (configure.in): Add AC_OFF_T and rearrange by type along the

	textutils, and sh-utils will get ChangeLog entries only in the
	sh-utils.

Tue Oct 04 20:42:46 1994  Jim Meyering  (meyering@comco.com)

	* od.c (my_strtoul): Set errno to zero before calling strtoul.
	Otherwise, od can fail complaining about a valid integer argument.
	From Andreas Schwab.

Sun Oct 02 17:57:09 1994  Jim Meyering  (meyering@comco.com)

	* tr.c (main): Give an error and fail when squeezing repeats
	and no non-options are given.  Reported by Tony Robinson
	(ajr@eng.cam.ac.uk).

	* sort.c (main): Temporarily copy each input file that might be
	another name for the output file.  When in doubt (e.g. a pipe),
	copy.  This allows the dangerous (historical -- in cnews) idiom
	`cat file | sort -o file' to work properly.  Don't rely on this
	behavior in new shell scripts.  From Paul Eggert (eggert@twinsun.com).

Mon Sep 26 18:01:47 1994  David J. MacKenzie  (djm@churchy.gnu.ai.mit.edu)

	* lib/xwrite.c safe-read.c memchr.c linebuffer.c full-write.c:

Sat Aug 27 16:57:20 1994  Jim Meyering  (meyering@comco.com)

	* system.h [BROKEN_STAT_MACROS]: Remove unnecessary #ifdef's.

Sun Apr 24 10:54:08 1994  Jim Meyering  (meyering@comco.com)

	* configure.in [AC_SIZEOF_TYPE]: Update for autoconf-1.9.
	* memchr.c: Test SIZEOF_LONG instead of LONG_64_BITS.

Mon Apr 11 17:55:52 1994  Jim Meyering  (meyering@comco.com)

	* csplit.c (struct control): Add new field, repeat_forever.
	Remove now-unneeded definition of INT_MAX.
	(process_regexp): Test repeat_forever instead of comparing `repeat'

	(split_file): Don't even reference `repeat' count if repeat_forever
	is set.
	(new_control_record): Initialize repeat_forever field.
	(parse_repeat_count): Set it instead of setting repeat count to
	INT_MAX.

	explicit error message for too many arguments.

Fri Mar 25 18:11:19 1994  Jim Meyering  (meyering@comco.com)

	* configure.in: Use AC_VERBOSE, AC_CHECKING, and AC_WARN instead
	of explicit echo commands.
	[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.
	[AC_SIZEOF_TYPE]: Use this instead of deprecated AC_LONG_64_BITS.

	* cat.c (cat): The command `:|cat -s' failed on Irix5 because
	ioctl (d, FIONREAD,... now returns ENOSYS for pipes -- under Irix4
	it returned EINVAL.  Detect this.
	(main) [lint]: Initialize variables to suppress `used before
	initialized' warnings.

	* csplit.c: Change long option name from --suffix to --suffix-format.

	* od.c (skip): Correct a comment.
	(main): Don't output anything to stdout if the sole input file
	doesn't exist.  Reported by Bauke Jan Douma <bjd@dds.hacktic.nl>.

	LDFLAGS and CFLAGS.

Wed Jan 18 16:14:00 1994  Jim Meyering  (meyering@comco.com)

	* unexpand.c (unexpand): Don't segfault when given a name of a
	nonexistent file.
	* expand.c (expand): Ditto.
	Both from Bauke Jan Douma <bjd@dds.hacktic.nl>.

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).

	* csplit.c (load_buffer): Rather than incrementing buffer size,
	double it each time we fail to find a newline.  Otherwise, csplit
	would run out of memory when processing files with very long lines.

Mon Jan 10 01:20:38 1994  Jim Meyering  (meyering@comco.com)

	* man/Makefile.in (manprefix): Use binprefix as the default.

	Makefile.in [DISTFILES]: Add it.

Wed Dec 22 18:52:44 1993  Jim Meyering  (meyering@comco.com)

	* memcmp.c: Use the latest version from the GNU C library.

	* cut.c [ADD_RANGE_PAIR]: New macro.
	(set_fields): Collect the list of all selected ranges before
	allocating and initializing the boolean lookup table.
	(cut_bytes, cut_fields): Complete rewrite.  Avoid copying
	into buffer whenever possible.  Properly handle input without
	trailing newline.
	(getstr): New function.  Copied from getline.c, but with minor changes.

	* sort.c (main): Properly handle -Tdir.
	Before, `sort -T/var/tmp' gave `sort: unrecognized option `-v''.
	Reported by Kristoffer Rose (kris@diku.dk).

	* cut.c (main): Give separate errors for `-s without -f'
	and `-d without -f'.
	(main): Now -d '' means `use the NUL byte as the delimiter'.
	Before, it got an error.

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.

Thu Dec 02 23:53:03 1993  Jim Meyering  (meyering@comco.com)

	* configure.in (AC_HAVE_FUNCS): Add isascii.
	* system.h [!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).

Fri Nov 19 22:41:48 1993  Jim Meyering  (meyering@comco.com)

	 * configure.in: Don't run the test for 8-bit clean memcmp if we
	 already know we'll be using our replacement.

Fri Nov 12 00:44:49 1993  Jim Meyering  (meyering@comco.com)

	* Version 1.9.1.

	* tac.c (usage): Fix typo in long usage.
	* sort.c (usage): Likewise.
	From Philippe.Schnoebelen@imag.fr.

	* cut.c [FATAL_ERROR]: New macro.
	(main): Call both error and usage (2) through FATAL_ERROR in
	many places.  Before, only `error (2...' was called.
	(invalid_list): Removed.  This function is subsumed by FATAL_ERROR.

	* cut.c (cut_fields): Properly handle input lacking a terminating

	* pr.c (cols_ready_to_print): New function.  It replaces a global
	variable by the same name and computes on the fly the value that

	put to rest the `pr -2a' bug.
	(main): Don't let getopt_long reorder arguments so we can
	distinguish between `pr -1 -2' and `pr -12'.  Rework handling of
	-n and +n options.

	* src/Makefile.in [.c.o]: Add -I$(srcdir) for version.h.

	* Makefile.in [CFLAGS, LDFLAGS]: Don't set to -g explicitely;
	configure's AC_SUBST will set these.

	* Makefile.in [Makefile]: Add dependencies and a rule to remake it.

	* sort.c (mergefps): Maintain keybeg and keylim when copying
	the current line to `saved'.
	(numcompare): Skip white space here since -n no longer implies -b.
	(getmonth): Skip white space here since -M no longer implies -b.
	(compare): Completely overhauled to make the 8th bit work right,
	also to properly handle the global reverse option.
	(set_ordering): -n no longer implies -b, according to Posix.

	conjunct) using nested if statements to make it clear that we do
