+But in fact, some languages have dialects in different countries.  For
+example, `de_AT' is used for Austria, and `pt_BR' for Brazil.  The
+country code serves to distinguish the dialects.
+
+   Not all programs have translations for all languages.  By default, an
+English message is shown in place of a nonexistent translation.  If you
+understand other languages, you can set up a priority list of languages.
+This is done through a different environment variable, called
+`LANGUAGE'.  GNU `gettext' gives preference to `LANGUAGE' over `LANG'
+for the purpose of message handling, but you still need to have `LANG'
+set to the primary language; this is required by other parts of the
+system libraries.  For example, some Swedish users who would rather
+read translations in German than English for when Swedish is not
+available, set `LANGUAGE' to `sv:de' while leaving `LANG' to `sv_SE'.
+
+   In the `LANGUAGE' environment variable, but not in the `LANG'
+environment variable, `LL_CC' combinations can be abbreviated as `LL'
+to denote the language's main dialect.  For example, `de' is equivalent
+to `de_DE' (German as spoken in Germany), and `pt' to `pt_PT'

+Using `gettext' in new packages
+===============================
+
+   If you are writing a freely available program and want to
+internationalize it you are welcome to use GNU `gettext' in your
+package.  Of course you have to respect the GNU Library General Public
+License which covers the use of the GNU `gettext' library.  This means
+in particular that even non-free programs can use `libintl' as a shared
+library, whereas only free software can use `libintl' as a static
+library or use modified versions of `libintl'.
+
+   Once the sources are changed appropriately and the setup can handle
+to use of `gettext' the only thing missing are the translations.  The
+Free Translation Project is also available for packages which are not
+developed inside the GNU project.  Therefore the information given above
+applies also for every other Free Software Project.  Contact
+`translation@iro.umontreal.ca' to make the `.pot' files available to
+the translation teams.

+
+2001-11-07  Paul Eggert  <eggert@twinsun.com>
+
+	* coreutils.texi (paste invocation): Give examples.
+	Thanks to Dan Jacobson for suggesting the examples.
+
+2001-11-05  Jim Meyering  <meyering@lucent.com>
+
+	* coreutils.texi (sort invocation): Recommend setting LC_ALL=C,
+	not LC_COLLATE=C.  Explain how the latter can cause problems.
+	Based on a message from Paul Eggert.
+	(ls invocation): Recommend setting LC_ALL=C, not LC_COLLATE=C.
+
+2001-10-21  Jim Meyering  <meyering@lucent.com>
+
+	* coreutils.texi (cp invocation): Describe --reply=...
+
+2001-10-17  Jim Meyering  <meyering@lucent.com>
+
+	* coreutils.texi (cp invocation): `cp --no-dereference' is
+	no longer equivalent to `cp -d'.
+	`cp -d' is equivalent to `--no-dereference --preserve=links'.
+	cp's -P option means --no-dereference, not --parents.
+	Describe new optional argument to --preserve.
+	Describe new option: --no-preserve=ATTRIBUTE_LIST.
+
+2001-09-23  Jim Meyering  <meyering@lucent.com>
+
+	* Makefile.am (check-texinfo): Redirect stderr of `grep -w' to
+	/dev/null, so people with old versions of grep don't see the failure.
+
+2001-09-16  Jim Meyering  <meyering@lucent.com>
+
+	* coreutils.texi (mv invocation): Describe new option:
+	--reply={yes,no,query}.  Fix a few typos.
+
+2001-09-15  Paul Eggert  <eggert@twinsun.com>
+
+	* coreutils.texi (uniq invocation): The input need not
+	be sorted.  Try to clarify -d versus -D versus -u.
+
+2001-09-12  Jim Meyering  <meyering@lucent.com>
+
+	* coreutils.texi (tail invocation): Document new option: -F.
+	From Herbert Xu.
+
+2001-09-04  Paul Eggert  <eggert@twinsun.com>
+
+	* coreutils.texi (join invocation): Describe the GNU
+	extension to join, which does not require sorted input when
+	the input contains no unpairable lines.
+
+2001-09-03  Paul Eggert  <eggert@twinsun.com>
+
+	* coreutils.texi:
+	New 'uname' options -i or --hardware-platform,
+	and -o or --operating-system.
+	'uname -a' now outputs -i and -o information at the end.
+	New uname option --kernel-version is an alias for -v.
+	Uname option --release has been renamed to --kernel-release,
+	and --sysname has been renamed to --kernel-name;
+	the old options will work for a while, but are no longer documented.
+
+2001-08-24  Herbert Xu  <herbert@gondor.apana.org.au>
+
+	* coreutils.texi (cut invocation): Document how cut treats lines
+	with no separators.
+
+2001-06-19  Paul Eggert  <eggert@twinsun.com>
+
+	* coreutils.texi: expr now uses LC_COLLATE for string comparison,
+	as per POSIX.
+
+2001-08-25  Jim Meyering  <meyering@lucent.com>
+
+	* coreutils.texi: Use @option, rather than @samp everywhere.
+
+2001-06-21  Paul Eggert  <eggert@twinsun.com>
+
+	* coreutils.texi: 'expr' now requires '+' rather than 'quote'
+	to quote tokens.
+
+2001-07-14  Jim Meyering  <meyering@lucent.com>
+
+	* coreutils.texi (cp invocation): Reflect 2001-07-08 change to
+	cp (via copy.c).
+
+2001-06-16  Jim Meyering  <meyering@lucent.com>
+
+	* Makefile.am (info_TEXINFOS): Reflect renaming: s/omni-/core/.
+	* coreutils.texi: Likewise.
+
+	* coreutils.texi: New, renamed from omni-utils.texi.
+	* omni-utils.texi: Removed, renamed to coreutils.texi.

+* How to use this License for your documents::
+@end menu
+@end ifnottex
+@display
+Copyright (C) 2000  Free Software Foundation, Inc.
+59 Temple Place, Suite 330, Boston, MA  02111-1307  USA
+
+Everyone is permitted to copy and distribute verbatim copies

+@item
+PREAMBLE
+
+The purpose of this License is to make a manual, textbook, or other
+written document ``free'' in the sense of freedom: to assure everyone
+the effective freedom to copy and redistribute it, with or without
+modifying it, either commercially or noncommercially.  Secondarily,
+this License preserves for the author and publisher a way to get
+credit for their work, while not being considered responsible for
+modifications made by others.
+
+This License is a kind of ``copyleft'', which means that derivative
+works of the document must themselves be free in the same sense.  It
+complements the GNU General Public License, which is a copyleft
+license designed for free software.
+
+We have designed this License in order to use it for manuals for free
+software, because free software needs free documentation: a free
+program should come with manuals providing the same freedoms that the
+software does.  But this License is not limited to software manuals;
+it can be used for any textual work, regardless of subject matter or
+whether it is published as a printed book.  We recommend this License
+principally for works whose purpose is instruction or reference.
+@iftex
+@sp1
+@end iftex
+@item
+APPLICABILITY AND DEFINITIONS
+
+This License applies to any manual or other work that contains a
+notice placed by the copyright holder saying it can be distributed
+under the terms of this License.  The ``Document'', below, refers to any
+such manual or work.  Any member of the public is a licensee, and is
+addressed as ``you''.
+
+A ``Modified Version'' of the Document means any work containing the
+Document or a portion of it, either copied verbatim, or with
+modifications and/or translated into another language.
+
+A ``Secondary Section'' is a named appendix or a front-matter section of
+the Document that deals exclusively with the relationship of the
+publishers or authors of the Document to the Document's overall subject
+(or to related matters) and contains nothing that could fall directly
+within that overall subject.  (For example, if the Document is in part a
+textbook of mathematics, a Secondary Section may not explain any
+mathematics.)  The relationship could be a matter of historical
+connection with the subject or with related matters, or of legal,
+commercial, philosophical, ethical or political position regarding
+them.
+
+The ``Invariant Sections'' are certain Secondary Sections whose titles
+are designated, as being those of Invariant Sections, in the notice
+that says that the Document is released under this License.
+
+The ``Cover Texts'' are certain short passages of text that are listed,
+as Front-Cover Texts or Back-Cover Texts, in the notice that says that
+the Document is released under this License.
+
+A ``Transparent'' copy of the Document means a machine-readable copy,
+represented in a format whose specification is available to the
+general public, whose contents can be viewed and edited directly and
+straightforwardly with generic text editors or (for images composed of
+pixels) generic paint programs or (for drawings) some widely available
+drawing editor, and that is suitable for input to text formatters or
+for automatic translation to a variety of formats suitable for input
+to text formatters.  A copy made in an otherwise Transparent file
+format whose markup has been designed to thwart or discourage
+subsequent modification by readers is not Transparent.  A copy that is
+not ``Transparent'' is called ``Opaque''.
+
+Examples of suitable formats for Transparent copies include plain
+ASCII without markup, Texinfo input format, LaTeX input format, SGML
+or XML using a publicly available DTD, and standard-conforming simple
+HTML designed for human modification.  Opaque formats include
+PostScript, PDF, proprietary formats that can be read and edited only
+by proprietary word processors, SGML or XML for which the DTD and/or
+processing tools are not generally available, and the
+machine-generated HTML produced by some word processors for output
+purposes only.
+
+The ``Title Page'' means, for a printed book, the title page itself,
+plus such following pages as are needed to hold, legibly, the material
+this License requires to appear in the title page.  For works in
+formats which do not have any title page as such, ``Title Page'' means
+the text near the most prominent appearance of the work's title,
+preceding the beginning of the body of the text.
+@iftex
+@sp1
+@end iftex
+@item
+VERBATIM COPYING
+
+You may copy and distribute the Document in any medium, either
+commercially or noncommercially, provided that this License, the
+copyright notices, and the license notice saying this License applies
+to the Document are reproduced in all copies, and that you add no other
+conditions whatsoever to those of this License.  You may not use
+technical measures to obstruct or control the reading or further
+copying of the copies you make or distribute.  However, you may accept
+compensation in exchange for copies.  If you distribute a large enough
+number of copies you must also follow the conditions in section 3.
+
+You may also lend copies, under the same conditions stated above, and
+you may publicly display copies.
+@iftex
+@sp1
+@end iftex
+@item
+COPYING IN QUANTITY
+
+If you publish printed copies of the Document numbering more than 100,
+and the Document's license notice requires Cover Texts, you must enclose
+the copies in covers that carry, clearly and legibly, all these Cover
+Texts: Front-Cover Texts on the front cover, and Back-Cover Texts on
+the back cover.  Both covers must also clearly and legibly identify
+you as the publisher of these copies.  The front cover must present
+the full title with all words of the title equally prominent and
+visible.  You may add other material on the covers in addition.
+Copying with changes limited to the covers, as long as they preserve
+the title of the Document and satisfy these conditions, can be treated
+as verbatim copying in other respects.
+
+If the required texts for either cover are too voluminous to fit
+legibly, you should put the first ones listed (as many as fit
+reasonably) on the actual cover, and continue the rest onto adjacent
+pages.
+
+If you publish or distribute Opaque copies of the Document numbering
+more than 100, you must either include a machine-readable Transparent
+copy along with each Opaque copy, or state in or with each Opaque copy
+a publicly-accessible computer-network location containing a complete
+Transparent copy of the Document, free of added material, which the
+general network-using public has access to download anonymously at no
+charge using public-standard network protocols.  If you use the latter
+option, you must take reasonably prudent steps, when you begin
+distribution of Opaque copies in quantity, to ensure that this
+Transparent copy will remain thus accessible at the stated location
+until at least one year after the last time you distribute an Opaque
+copy (directly or through your agents or retailers) of that edition to
+the public.
+
+It is requested, but not required, that you contact the authors of the
+Document well before redistributing any large number of copies, to give
+them a chance to provide you with an updated version of the Document.
+@iftex
+@sp1
+@end iftex
+@item
+MODIFICATIONS
+
+You may copy and distribute a Modified Version of the Document under
+the conditions of sections 2 and 3 above, provided that you release
+the Modified Version under precisely this License, with the Modified
+Version filling the role of the Document, thus licensing distribution
+and modification of the Modified Version to whoever possesses a copy
+of it.  In addition, you must do these things in the Modified Version:
+
+A. Use in the Title Page (and on the covers, if any) a title distinct
+   from that of the Document, and from those of previous versions
+   (which should, if there were any, be listed in the History section
+   of the Document).  You may use the same title as a previous version
+   if the original publisher of that version gives permission.@*
+B. List on the Title Page, as authors, one or more persons or entities
+   responsible for authorship of the modifications in the Modified
+   Version, together with at least five of the principal authors of the
+   Document (all of its principal authors, if it has less than five).@*
+C. State on the Title page the name of the publisher of the
+   Modified Version, as the publisher.@*
+D. Preserve all the copyright notices of the Document.@*
+E. Add an appropriate copyright notice for your modifications
+   adjacent to the other copyright notices.@*
+F. Include, immediately after the copyright notices, a license notice
+   giving the public permission to use the Modified Version under the
+   terms of this License, in the form shown in the Addendum below.@*
+G. Preserve in that license notice the full lists of Invariant Sections
+   and required Cover Texts given in the Document's license notice.@*
+H. Include an unaltered copy of this License.@*
+I. Preserve the section entitled ``History'', and its title, and add to
+   it an item stating at least the title, year, new authors, and
+   publisher of the Modified Version as given on the Title Page.  If
+   there is no section entitled ``History'' in the Document, create one
+   stating the title, year, authors, and publisher of the Document as
+   given on its Title Page, then add an item describing the Modified
+   Version as stated in the previous sentence.@*
+J. Preserve the network location, if any, given in the Document for
+   public access to a Transparent copy of the Document, and likewise
+   the network locations given in the Document for previous versions
+   it was based on.  These may be placed in the ``History'' section.
+   You may omit a network location for a work that was published at
+   least four years before the Document itself, or if the original
+   publisher of the version it refers to gives permission.@*
+K. In any section entitled ``Acknowledgements'' or ``Dedications'',
+   preserve the section's title, and preserve in the section all the
+   substance and tone of each of the contributor acknowledgements
+   and/or dedications given therein.@*
+L. Preserve all the Invariant Sections of the Document,
+   unaltered in their text and in their titles.  Section numbers
+   or the equivalent are not considered part of the section titles.@*
+M. Delete any section entitled ``Endorsements''.  Such a section
+   may not be included in the Modified Version.@*
+N. Do not retitle any existing section as ``Endorsements''
+   or to conflict in title with any Invariant Section.@*
+@iftex
+@sp1
+@end iftex
+If the Modified Version includes new front-matter sections or
+appendices that qualify as Secondary Sections and contain no material
+copied from the Document, you may at your option designate some or all
+of these sections as invariant.  To do this, add their titles to the
+list of Invariant Sections in the Modified Version's license notice.
+These titles must be distinct from any other section titles.
+
+You may add a section entitled ``Endorsements'', provided it contains
+nothing but endorsements of your Modified Version by various
+parties--for example, statements of peer review or that the text has
+been approved by an organization as the authoritative definition of a
+standard.
+
+You may add a passage of up to five words as a Front-Cover Text, and a
+passage of up to 25 words as a Back-Cover Text, to the end of the list

+Front-Cover Text and one of Back-Cover Text may be added by (or
+through arrangements made by) any one entity.  If the Document already
+includes a cover text for the same cover, previously added by you or

+COMBINING DOCUMENTS
+
+You may combine the Document with other documents released under this
+License, under the terms defined in section 4 above for modified
+versions, provided that you include in the combination all of the
+Invariant Sections of all of the original documents, unmodified, and
+list them all as Invariant Sections of your combined work in its
+license notice.
+
+The combined work need only contain one copy of this License, and
+multiple identical Invariant Sections may be replaced with a single
+copy.  If there are multiple Invariant Sections with the same name but
+different contents, make the title of each such section unique by
+adding at the end of it, in parentheses, the name of the original
+author or publisher of that section if known, or else a unique number.
+Make the same adjustment to the section titles in the list of
+Invariant Sections in the license notice of the combined work.
+
+In the combination, you must combine any sections entitled ``History''
+in the various original documents, forming one section entitled
+``History''; likewise combine any sections entitled ``Acknowledgements'',
+and any sections entitled ``Dedications''.  You must delete all sections
+entitled ``Endorsements.''

+License in the various documents with a single copy that is included in
+the collection, provided that you follow the rules of this License for
+verbatim copying of each of the documents in all other respects.

+AGGREGATION WITH INDEPENDENT WORKS
+
+A compilation of the Document or its derivatives with other separate
+and independent documents or works, in or on a volume of a storage or
+distribution medium, does not as a whole count as a Modified Version
+of the Document, provided no compilation copyright is claimed for the
+compilation.  Such a compilation is called an ``aggregate'', and this
+License does not apply to the other self-contained works thus compiled
+with the Document, on account of their being thus compiled, if they
+are not themselves derivative works of the Document.
+
+If the Cover Text requirement of section 3 is applicable to these
+copies of the Document, then if the Document is less than one quarter
+of the entire aggregate, the Document's Cover Texts may be placed on
+covers that surround only the Document within the aggregate.
+Otherwise they must appear on covers around the whole aggregate.

+TRANSLATION

+Replacing Invariant Sections with translations requires special
+permission from their copyright holders, but you may include
+translations of some or all Invariant Sections in addition to the
+original versions of these Invariant Sections.  You may include a
+translation of this License provided that you also include the

+	(TEMPORARIES): New macro.
+	(__gen_tempname): Use TEMPORARIES rather than TMP_MAX.  This

+2001-09-25  Volker Borchert  <bt@teknon.de>

+
+	* mountlist.c: Remove useless parentheses in #if directives.
+	(MOUNTED) [!defined MOUNTED]: Define to _PATH_MOUNTED, for when

+
+	* xstrtol.c (strtoimax): Guard declaration with
+	`#if !HAVE_DECL_STRTOIMAX', rather than just `#ifndef strtoimax'.
+	The latter fails because some systems (at least rs6000-ibm-aix4.3.3.0)
+	have their own, conflicting declaration of strtoimax in sys/inttypes.h.
+	(strtoumax): Likewise, for completeness (it wasn't necessary).
+
+2001-09-06  Paul Eggert  <eggert@twinsun.com>
+
+	* strtoimax.c (HAVE_LONG_LONG):
+	Redefine to HAVE_UNSIGNED_LONG_LONG if unsigned.

+	to work around bug in IBM C compiler.
+
+2001-09-16  Jim Meyering  <meyering@lucent.com>
+
+	* mkdir.c: New file.
+
+2001-09-04  Paul Eggert  <eggert@twinsun.com>
+
+	* xgetcwd.c: Revert some of the previous change; intead,
+	fix the HAVE_GETCWD_NULL code to behave more like the
+	!HAVE_GETCWD_NULL code used to.
+
+	Include "xalloc.h".
+	(xgetcwd): Do not return NULL when memory is exhausted; instead,
+	invoke xalloc_die.
+
+2001-09-04  Paul Eggert  <eggert@twinsun.com>
+
+	* xreadlink.c (xreadlink): Omit size_t* arg.  All uses changed.
+	Use ssize_t, not int, to store result of readlink.
+	Check for ssize_t overflow as well as size_t overflow,
+	as POSIX says the result of readlink is implementation-defined
+	when ssize_t overflows.
+	Remove unnecessary cast to char*.
+	Use free+malloc instead of realloc, as the storage doesn't need
+	to be preserved and it's clearer and can be more efficient that way.
+	(SIZE_MAX, SSIZE_MAX): New macros, if <limits.h> doesn't declare.
+	* xreadlink.h (xreadlink): Update prototype.
+
+2001-09-03  Paul Eggert  <eggert@twinsun.com>
+
+	* exclude.c (fnmatch_no_wildcards): Fix confusion between
+	usage of FNM_CASEFOLD and FNM_LEADING_DIR.  The bug was
+	spotted by Jim Meyering.
+
+2001-09-03  Jim Meyering  <meyering@lucent.com>
+
+	* xreadlink.c (xreadlink): Preserve errno around `free' during failure.
+
+2001-09-03  Paul Eggert  <eggert@twinsun.com>
+
+	* xgetcwd.c: Fix the !HAVE_GETCWD_NULL code to behave more
+	like the HAVE_GETCWD_NULL code.
+	Include pathmax.h if not HAVE_GETCWD.
+	Do not include xalloc.h.
+	(INITIAL_BUFFER_SIZE): New symbol.
+	Do not use xmalloc / xrealloc, since the caller is responsible for
+	handling errors.  Preserve errno around `free' during failure.
+	Do not overrun buffer when using getwd.
+
+2001-09-03  Paul Eggert  <eggert@twinsun.com>
+
+	* xgetcwd.c (xgetcwd): Use HAVE_GETCWD_NULL, not (defined
+	__GLIBC__ && __GLIBC__ >= 2), to decide whether to use getcwd (NULL, 0).
+
+2001-09-02  Jim Meyering  <meyering@lucent.com>
+

+
+2001-09-01  Jim Meyering  <meyering@lucent.com>
+
+	* xreadlink.c: New file.
+	* xreadlink.h: New file.
+	* Makefile.am (libfetish_a_SOURCES): Add xreadlink.c and xreadlink.h.
+
+	* regex.c (uintptr_t) [!_LIBC]: Define to private_uintptr_t, so it
+	doesn't conflict with sparc-sun-solaris2.7's definition in
+	/usr/include/sys/int_types.h.
+
+	* exclude.c: Use `""', not `<>' to #include non-system header files.
+	(fnmatch_no_wildcards): Rewrite not to use function names, strcasecmp
+	and strncasecmp as r-values.  Unixware didn't have declarations.
+
+2001-08-31  Jim Meyering  <meyering@lucent.com>
+
+	* xgetcwd.c (xgetcwd): Reorganize to avoid some duplication.
+	Use an initial, malloc'd, buffer of length 128 rather than
+	a statically allocated one of length 1024.
+
+2001-08-30  Paul Eggert  <eggert@twinsun.com>
+
+	* xgetcwd.c: Don't include pathmax.h.
+	Include stdlib.h and unistd.h if available.
+	Include xalloc.h.
+	(xmalloc, xstrdup, free): Remove decls.
+	(xgetcwd): Don't assume sizes fit in unsigned.
+	Check for overflow when computing sizes.
+	Simplify reallocation code.
+
+2001-08-28  Paul Eggert  <eggert@twinsun.com>
+
+	* Makefile.am (libfetish_a_SOURCES): Remove strtoxmax.c.
+
+	* strtoimax.c: Renamed from strtoxmax.c, removing the
+	old strtoimax.c.
+
+	Also, make the following further changes to make this file's
+	configuration more similar to that of strtol.c:
+	(UNSIGNED): Renamed from STRTOUXMAX_UNSIGNED.  All uses changed.
+	(strtoumax, uintmax_t, strtoull, strtol): Remove.
+	(intmax_t, strtoimax, strtol, strtoll): New macros, if UNSIGNED.
+	(strtoimax): Renamed from strtoumax.  All uses of unsigned values
+	changed to signed values.
+
+	And make the following changes as well:
+	Fix copyright notice, as 1999 was missing.
+	(verify): New macro.
+	(strtoimax): Check sizes at compile-time, not run-time.
+	Prefer strtol to strtoll if both work.
+	(main): Remove; it was not that useful and was a pain to maintain.
+
+	* strtoumax.c: Include strtoimax.c, not strtouxmax.c.
+
+2001-08-30  Paul Eggert  <eggert@twinsun.com>
+
+	* savedir.c (savedir): Remove size parameter, as POSIX says that
+	a directory's st_size can have an arbitrary value, so the old
+	usage could waste an arbitrary amount of memory.  All uses
+	changed.
+	* savedir.h: Update prototype.
+
+2001-08-30  Paul Eggert  <eggert@twinsun.com>
+
+	* xstrtol.c (strtoimax): New decl.
+
+2001-08-28  Paul Eggert  <eggert@twinsun.com>
+
+	* xstrtol.h: Add copyright notice.
+	(_DECLARE_XSTRTOL): Improve quality of diagnostic for
+	LONGINT_INVALID_SUFFIX_CHAR.
+
+2001-08-30  Paul Eggert  <eggert@twinsun.com>
+
+	* quotearg.c: BSD/OS 4.1 wchar.h requires FILE and struct
+	tm to be declared.
+
+2001-08-30  Paul Eggert  <eggert@twinsun.com>
+
+	* hash.c: Remove '2001' from copyright notice.
+
+2001-08-30  Paul Eggert  <eggert@twinsun.com>
+
+	* full-write.h: New file.
+	* Makefile.am (libfetish_a_SOURCES): Add full-write.h.
+	* full-write.c: Correct credits, as cccp.c no longer
+	exists and anyway it was so heavily changed from the old cccp
+	code as to be unrecognizable.  Include full-write.h.
+	(full_write) Return size_t, with short writes meaning failure.
+	All callers changed.  This fixes a bug with large buffers
+	on 64-bit hosts.
+	* utime.c: Include full-write.h.
+
+2001-08-30  Paul Eggert  <eggert@twinsun.com>
+
+	Merge 'exclude' changes from tar 1.13.22.
+	This fixes one or two unlikely storage allocation overflow bugs,
+	but doesn't change user-visible behavior otherwise.
+
+2001-08-30  Paul Eggert  <eggert@twinsun.com>
+
+	* exclude.c (bool): Declare, perhaps by including stdbool.h.
+	(<sys/types.h>): Include only if HAVE_SYS_TYPES_H.
+	(<stdlib.h>, <string.h>, <strings.h>, <inttypes.h>, <stdint.h>):
+	Include	if available.
+	(<xalloc.h>): Include
+	(SIZE_MAX): Define if <stdint.h> or <inttypes.h> doesn't.
+	(verify): New macro.  Use it to verify that EXCLUDE macros do not
+	collide with FNM macros.
+	(struct patopts): New struct.
+	(struct exclude): Use it, as exclude patterns now come with options.
+	(new_exclude): Support above changes.
+	(new_exclude, add_exclude_file):
+	Initial size must now be a power of two to simplify overflow checking.
+	(free_exclude, fnmatch_no_wildcards): New function.
+	(excluded_filename): No longer requires options arg, as the options
+	are determined by add_exclude.  Now returns bool, not int.
+	(excluded_filename, add_exclude):
+	Add support for the fancy new exclusion options.
+	(add_exclude, add_exclude_file): Now takes int options arg.
+	Check for arithmetic overflow when computing sizes.
+	(add_exclude_file): xrealloc might modify errno, so don't
+	realloc until after errno might be used.
+

+
+2001-05-11  Paul Eggert  <eggert@twinsun.com>
+
+	dirname code cleanup.  base_name now behaves more compatibly
+	with POSIX basename when given file names that have trailing
+	slashes, and similarly for dir_name.  Add new primitives
+	base_len and dir_len.  Put the directory-name-related decls
+	into dirname.h.
+
+	* addext.c (ISSLASH, base_name): Remove; now in dirname.h.
+	* backupfile.c (base_name): Likewise.

+	* dirname.c (FILESYSTEM_PREFIX_LEN, ISSLASH): Likewise.
+	* makepath.c (strip_trailing_slashes): Likewise.

+	* backupfile.c: Likewise.
+
+	* addext.c (addext): Use base_len to trim redundant
+	trailing slashes instead of doing it ourselves.
+	But do not trim the last slash if it is not redundant.
+
+	* backupfile.c (find_backup_file_name,
+	max_backup_version): Use base_len instead of rolling it ourselves.
+	Handle the case of "" and (on DOS) "C:" correctly.
+
+	* basename.c: Do not include <stdio.h>, <assert.h>; no longer needed.
+	Include <string.h>, <dirname.h>.
+	(base_name): Allow file names ending in slashes, other than names
+	that are all slashes.  In this case, return the basename followed
+	by the slashes.  This is more general, and can be used in places
+	where the original base_name purposely had an assertion failure.
+	(base_len): New function.
+
+	* dirname.c: Include <string.h> instead of <stdlib.h>.
+	Do not include <assert.h>; no longer needed.
+	Include xalloc.h.
+	(memrchr): Remove decl.
+	(dir_name_r): Remove.
+	(dir_len): Renamed from dirlen.  All callers changed.
+	Rewrite in terms of base_name, for simplicity and consistency.

+	New macros.
+	(base_name, base_len, dir_len, strip_trailing_slashes): New decls.
+
+	* path-concat.c (path_concat): Use base_len to compute
+	base length, not strlen; this means we cannot rely on memcpy
+	to null-terminate.
+
+	* same.c (STREQ): Remove.
+	(same_name): Handle the case where the basename ends in trailing '/'.
+
+	* stripslash.c (strip_trailing_slashes): Return nonzero if
+	a slash was stripped.  Do not strip the last slash after a
+	file system prefix.
+
+2001-04-08  Jim Meyering  <meyering@lucent.com>
+
+	* getdate.y (get_date): Set tm_isdst to -1 to ensure that it is
+	recomputed; that's necessary when the offset spans a DST transition.
+	Patch by David J. MacKenzie.  Reported by Hon-Yin Kok.
+
+2001-04-02  Jim Meyering  <meyering@lucent.com>

+
+2001-03-13  Jim Meyering  <meyering@lucent.com>

+	From Bruno Haible.
+
+2001-03-06  Bruno Haible  <haible@clisp.cons.org>
