+
+ fdopendir: fix a bug on systems lacking openat and /proc support
+ OpenBSD 4.7 is one such system. The most noticeable effect was
+ failure of any application making nontrivial use of fts: rm, du,
+ chown, chmod etc. E.g., "mkdir -p a/b; ./rm -rf a" would fail with
+ ./rm: traversal failed: `a': Bad file descriptor
+ Debugging that, you see that even though FD 6 was closed just
+ prior to the opendir call in fd_clone_opendir, its resulting
+ dir->dd_fd was 8, rather than the expected value of 6:
+
+ Breakpoint 3, fdopendir_with_dup (fd=6, older_dupfd=-1) at fdopendir.c:93
+ 93 close (fd);
+ (gdb) n
+ 94 dir = fd_clone_opendir (dupfd);
+ (gdb) n
+ 95 saved_errno = errno;
+ (gdb) p dir->dd_fd
+ $11 = 8
+
+ Notice how it closes FD 6, then gets a DIR* pointer using FD 8.
+ The problem is that on OpenBSD, fd_clone_opendir has to resort
+ to using the old-style save/restore CWD mechanism, due to its
+ lack of openat/proc support, and *that* would steal the FD (6)
+ that opendir was supposed to use.
+
+ The fix is to squirrel away the desired FD so that save_cwd uses a
+ different one, and then free the dest FD right before calling opendir.
+ That guarantees opendir will use the required file descriptor.
+
+ * lib/fdopendir.c (fd_clone_opendir): Handle the above.

+ Bison wants to include lib/gnulib.mk from the top-level makefile,

Important notes
---------------
+2010-09-04 gnulib-tool The option '--import' is no longer cumulative; it
+ now expects the complete list of modules and other
+ options on the command line. If you want to
+ augment (not set) the list of modules, use the
+ new option '--add-import' instead of '--import'.
+
User visible incompatible changes
---------------------------------
Date Modules Changes
+2010-10-05 getdate This module is deprecated. Please use the new
+ parse-datetime module for the replacement
+ function parse_datetime(), or help us write
+ getdate-posix for getdate(). Also, the header
+ "getdate.h" has been renamed "parse-datetime.h",
+ and doc/getdate.texi to doc/parse-datetime.texi.
+
+2010-09-29 sys_wait This module no longer provides the waitpid()
+ function. If you need this function, you now need
+ to request the 'waitpid' module.
+
+2010-09-17 utimens The function gl_futimens is removed, and its
+ signature has been migrated to fdutimens. Callers
+ of gl_futimens should change function name, and
+ callers of fdutimens should swap parameter order.
+
+2010-09-17 fdutimensat This function has a new signature: the fd now comes
+ first instead of the dir/name pair, and a new
+ atflag parameter is added at the end. Old code
+ should rearrange parameters, and pass 0 for atflag.
+
+2010-09-13 regex The module is not guaranteeing anymore support for
+ 64-bit regoff_t on 64-bit systems. The size of
+ regoff_t will always be 32-bit unless the program
+ is being configured --with-included-regex. This
+ may change again in the future once glibc provides
+ this feature as well.
+
+2010-09-12 savedir The fdsavedir function is now deprecated.
+
+2010-09-10 fcntl-h This module now defaults O_CLOEXEC to 0, and
+ it defaults O_EXEC and O_SEARCH to O_RDONLY.
+ Use "#if O_CLOEXEC" instead of "#ifdef O_CLOEXEC".
+
+2010-08-28 realloc This module is deprecated. Use 'realloc-gnu'
+ instead. It will be removed 2012-01-01.
+
+2010-08-28 calloc This module is deprecated. Use 'calloc-gnu'
+ instead. It will be removed 2012-01-01.
+
+2010-08-28 malloc This module is deprecated. Use 'malloc-gnu'
+ instead. It will be removed 2012-01-01.
+
2010-08-14 memxfrm This module is renamed to amemxfrm. The include
file is renamed to "amemxfrm.h". The function is
renamed to amemxfrm.

-@quotation
-Our units of temporal measurement, from seconds on up to months, are so
-complicated, asymmetrical and disjunctive so as to make coherent mental
-reckoning in time all but impossible. Indeed, had some tyrannical god
-contrived to enslave our minds to time, to make it all but impossible
-for us to escape subjection to sodden routines and unpleasant surprises,
-he could hardly have done better than handing down our present system.
-It is like a set of trapezoidal building blocks, with no vertical or
-horizontal surfaces, like a language in which the simplest thought
-demands ornate constructions, useless particles and lengthy
-circumlocutions. Unlike the more successful patterns of language and
-science, which enable us to face experience boldly or at least
-level-headedly, our system of temporal calculation silently and
-persistently encourages our terror of time.
-
-@dots{} It is as though architects had to measure length in feet, width
-in meters and height in ells; as though basic instruction manuals
-demanded a knowledge of five different languages. It is no wonder then
-that we often look into our own immediate past or future, last Tuesday
-or a week from Sunday, with feelings of helpless confusion. @dots{}

-@cindex items in date strings
-A @dfn{date} is a string, possibly empty, containing many items
-separated by whitespace. The whitespace may be omitted when no
-ambiguity arises. The empty string means the beginning of today (i.e.,
-midnight). Order of the items is immaterial. A date string may contain
-many flavors of items:
-
-@itemize @bullet
-@item calendar date items
-@item time of day items
-@item time zone items
-@item day of the week items
-@item relative items
-@item pure numbers.
-@end itemize
-
-@noindent We describe each of these item types in turn, below.
-
-@cindex numbers, written-out
-@cindex ordinal numbers
-@findex first @r{in date strings}
-@findex next @r{in date strings}
-@findex last @r{in date strings}
-A few ordinal numbers may be written out in words in some contexts. This is
-most useful for specifying day of the week items or relative items (see
-below). Among the most commonly used ordinal numbers, the word
-@samp{last} stands for @math{-1}, @samp{this} stands for 0, and
-@samp{first} and @samp{next} both stand for 1. Because the word
-@samp{second} stands for the unit of time there is no way to write the
-ordinal number 2, but for convenience @samp{third} stands for 3,
-@samp{fourth} for 4, @samp{fifth} for 5,
-@samp{sixth} for 6, @samp{seventh} for 7, @samp{eighth} for 8,
-@samp{ninth} for 9, @samp{tenth} for 10, @samp{eleventh} for 11 and
-@samp{twelfth} for 12.
-
-@cindex months, written-out
-When a month is written this way, it is still considered to be written
-numerically, instead of being ``spelled in full''; this changes the
-allowed strings.
-
-@cindex language, in dates
-In the current implementation, only English is supported for words and
-abbreviations like @samp{AM}, @samp{DST}, @samp{EST}, @samp{first},
-@samp{January}, @samp{Sunday}, @samp{tomorrow}, and @samp{year}.
-
-@cindex language, in dates
-@cindex time zone item
-The output of the @command{date} command
-is not always acceptable as a date string,
-not only because of the language problem, but also because there is no
-standard meaning for time zone items like @samp{IST}. When using
-@command{date} to generate a date string intended to be parsed later,
-specify a date format that is independent of language and that does not
-use time zone items other than @samp{UTC} and @samp{Z}. Here are some
-ways to do this:
-
-@example
-$ LC_ALL=C TZ=UTC0 date
-Mon Mar 1 00:21:42 UTC 2004
-$ TZ=UTC0 date +'%Y-%m-%d %H:%M:%SZ'
-2004-03-01 00:21:42Z
-$ date --iso-8601=ns | tr T ' ' # --iso-8601 is a GNU extension.
-2004-02-29 16:21:42,692722128-0800
-$ date --rfc-2822 # a GNU extension
-Sun, 29 Feb 2004 16:21:42 -0800
-$ date +'%Y-%m-%d %H:%M:%S %z' # %z is a GNU extension.
-2004-02-29 16:21:42 -0800
-$ date +'@@%s.%N' # %s and %N are GNU extensions.
-@@1078100502.692722128
-@end example
-
-@cindex case, ignored in dates
-@cindex comments, in dates
-Alphabetic case is completely ignored in dates. Comments may be introduced
-between round parentheses, as long as included parentheses are properly
-nested. Hyphens not followed by a digit are currently ignored. Leading
-zeros on numbers are ignored.
-
-Invalid dates like @samp{2005-02-29} or times like @samp{24:00} are
-rejected. In the typical case of a host that does not support leap
-seconds, a time like @samp{23:59:60} is rejected even if it
-corresponds to a valid leap second.
-
-
-@node Calendar date items
-@section Calendar date items
-
-@cindex calendar date item
-
-A @dfn{calendar date item} specifies a day of the year. It is
-specified differently, depending on whether the month is specified
-numerically or literally. All these strings specify the same calendar date:
-
-@example
-1972-09-24 # @sc{iso} 8601.
-72-9-24 # Assume 19xx for 69 through 99,
- # 20xx for 00 through 68.
-72-09-24 # Leading zeros are ignored.
-9/24/72 # Common U.S. writing.
-24 September 1972
-24 Sept 72 # September has a special abbreviation.
-24 Sep 72 # Three-letter abbreviations always allowed.
-Sep 24, 1972
-24-sep-72
-24sep72
-@end example
-
-The year can also be omitted. In this case, the last specified year is
-used, or the current year if none. For example:
-
-@example
-9/24
-sep 24
-@end example
-
-Here are the rules.
-
-@cindex @sc{iso} 8601 date format
-@cindex date format, @sc{iso} 8601
-For numeric months, the @sc{iso} 8601 format
-@samp{@var{year}-@var{month}-@var{day}} is allowed, where @var{year} is
-any positive number, @var{month} is a number between 01 and 12, and
-@var{day} is a number between 01 and 31. A leading zero must be present
-if a number is less than ten. If @var{year} is 68 or smaller, then 2000
-is added to it; otherwise, if @var{year} is less than 100,
-then 1900 is added to it. The construct
-@samp{@var{month}/@var{day}/@var{year}}, popular in the United States,
-is accepted. Also @samp{@var{month}/@var{day}}, omitting the year.
-
-@cindex month names in date strings
-@cindex abbreviations for months
-Literal months may be spelled out in full: @samp{January},
-@samp{February}, @samp{March}, @samp{April}, @samp{May}, @samp{June},
-@samp{July}, @samp{August}, @samp{September}, @samp{October},
-@samp{November} or @samp{December}. Literal months may be abbreviated
-to their first three letters, possibly followed by an abbreviating dot.
-It is also permitted to write @samp{Sept} instead of @samp{September}.
-
-When months are written literally, the calendar date may be given as any
-of the following:
-
-@example
-@var{day} @var{month} @var{year}
-@var{day} @var{month}
-@var{month} @var{day} @var{year}
-@var{day}-@var{month}-@var{year}
-@end example
-
-Or, omitting the year:
-
-@example
-@var{month} @var{day}
-@end example
-
-
-@node Time of day items
-@section Time of day items
-
-@cindex time of day item
-
-A @dfn{time of day item} in date strings specifies the time on a given
-day. Here are some examples, all of which represent the same time:
-
-@example
-20:02:00.000000
-20:02
-8:02pm
-20:02-0500 # In @sc{est} (U.S. Eastern Standard Time).
-@end example
-
-More generally, the time of day may be given as
-@samp{@var{hour}:@var{minute}:@var{second}}, where @var{hour} is
-a number between 0 and 23, @var{minute} is a number between 0 and
-59, and @var{second} is a number between 0 and 59 possibly followed by
-@samp{.} or @samp{,} and a fraction containing one or more digits.
-Alternatively,
-@samp{:@var{second}} can be omitted, in which case it is taken to
-be zero. On the rare hosts that support leap seconds, @var{second}
-may be 60.
-
-@findex am @r{in date strings}
-@findex pm @r{in date strings}
-@findex midnight @r{in date strings}
-@findex noon @r{in date strings}
-If the time is followed by @samp{am} or @samp{pm} (or @samp{a.m.}
-or @samp{p.m.}), @var{hour} is restricted to run from 1 to 12, and
-@samp{:@var{minute}} may be omitted (taken to be zero). @samp{am}
-indicates the first half of the day, @samp{pm} indicates the second
-half of the day. In this notation, 12 is the predecessor of 1:
-midnight is @samp{12am} while noon is @samp{12pm}.
-(This is the zero-oriented interpretation of @samp{12am} and @samp{12pm},
-as opposed to the old tradition derived from Latin
-which uses @samp{12m} for noon and @samp{12pm} for midnight.)
-
-@cindex time zone correction
-@cindex minutes, time zone correction by
-The time may alternatively be followed by a time zone correction,
-expressed as @samp{@var{s}@var{hh}@var{mm}}, where @var{s} is @samp{+}
-or @samp{-}, @var{hh} is a number of zone hours and @var{mm} is a number
-of zone minutes.
-The zone minutes term, @var{mm}, may be omitted, in which case
-the one- or two-digit correction is interpreted as a number of hours.
-You can also separate @var{hh} from @var{mm} with a colon.
-When a time zone correction is given this way, it
-forces interpretation of the time relative to
-Coordinated Universal Time (@sc{utc}), overriding any previous
-specification for the time zone or the local time zone. For example,
-@samp{+0530} and @samp{+05:30} both stand for the time zone 5.5 hours
-ahead of @sc{utc} (e.g., India).
-This is the best way to
-specify a time zone correction by fractional parts of an hour.
-The maximum zone correction is 24 hours.
-
-Either @samp{am}/@samp{pm} or a time zone correction may be specified,
-but not both.
-
-
-@node Time zone items
-@section Time zone items
-
-@cindex time zone item
-
-A @dfn{time zone item} specifies an international time zone, indicated
-by a small set of letters, e.g., @samp{UTC} or @samp{Z}
-for Coordinated Universal
-Time. Any included periods are ignored. By following a
-non-daylight-saving time zone by the string @samp{DST} in a separate
-word (that is, separated by some white space), the corresponding
-daylight saving time zone may be specified.
-Alternatively, a non-daylight-saving time zone can be followed by a
-time zone correction, to add the two values. This is normally done
-only for @samp{UTC}; for example, @samp{UTC+05:30} is equivalent to
-@samp{+05:30}.
-
-Time zone items other than @samp{UTC} and @samp{Z}
-are obsolescent and are not recommended, because they
-are ambiguous; for example, @samp{EST} has a different meaning in
-Australia than in the United States. Instead, it's better to use
-unambiguous numeric time zone corrections like @samp{-0500}, as
-described in the previous section.
-
-If neither a time zone item nor a time zone correction is supplied,
-time stamps are interpreted using the rules of the default time zone
-(@pxref{Specifying time zone rules}).
-
-
-@node Day of week items
-@section Day of week items
-
-@cindex day of week item
-
-The explicit mention of a day of the week will forward the date
-(only if necessary) to reach that day of the week in the future.
-
-Days of the week may be spelled out in full: @samp{Sunday},
-@samp{Monday}, @samp{Tuesday}, @samp{Wednesday}, @samp{Thursday},
-@samp{Friday} or @samp{Saturday}. Days may be abbreviated to their
-first three letters, optionally followed by a period. The special
-abbreviations @samp{Tues} for @samp{Tuesday}, @samp{Wednes} for
-@samp{Wednesday} and @samp{Thur} or @samp{Thurs} for @samp{Thursday} are
-also allowed.
-
-@findex next @var{day}
-@findex last @var{day}
-A number may precede a day of the week item to move forward
-supplementary weeks. It is best used in expression like @samp{third
-monday}. In this context, @samp{last @var{day}} or @samp{next
-@var{day}} is also acceptable; they move one week before or after
-the day that @var{day} by itself would represent.
-
-A comma following a day of the week item is ignored.
-
-
-@node Relative items in date strings
-@section Relative items in date strings
-
-@cindex relative items in date strings
-@cindex displacement of dates
-
-@dfn{Relative items} adjust a date (or the current date if none) forward
-or backward. The effects of relative items accumulate. Here are some
-examples:
-
-@example
-1 year
-1 year ago
-3 years
-2 days
-@end example
-
-@findex year @r{in date strings}
-@findex month @r{in date strings}
-@findex fortnight @r{in date strings}
-@findex week @r{in date strings}
-@findex day @r{in date strings}
-@findex hour @r{in date strings}
-@findex minute @r{in date strings}
-The unit of time displacement may be selected by the string @samp{year}
-or @samp{month} for moving by whole years or months. These are fuzzy
-units, as years and months are not all of equal duration. More precise
-units are @samp{fortnight} which is worth 14 days, @samp{week} worth 7
-days, @samp{day} worth 24 hours, @samp{hour} worth 60 minutes,
-@samp{minute} or @samp{min} worth 60 seconds, and @samp{second} or
-@samp{sec} worth one second. An @samp{s} suffix on these units is
-accepted and ignored.
-
-@findex ago @r{in date strings}
-The unit of time may be preceded by a multiplier, given as an optionally
-signed number. Unsigned numbers are taken as positively signed. No
-number at all implies 1 for a multiplier. Following a relative item by
-the string @samp{ago} is equivalent to preceding the unit by a
-multiplier with value @math{-1}.
-
-@findex day @r{in date strings}
-@findex tomorrow @r{in date strings}
-@findex yesterday @r{in date strings}
-The string @samp{tomorrow} is worth one day in the future (equivalent
-to @samp{day}), the string @samp{yesterday} is worth
-one day in the past (equivalent to @samp{day ago}).
-
-@findex now @r{in date strings}
-@findex today @r{in date strings}
-@findex this @r{in date strings}
-The strings @samp{now} or @samp{today} are relative items corresponding
-to zero-valued time displacement, these strings come from the fact
-a zero-valued time displacement represents the current time when not
-otherwise changed by previous items. They may be used to stress other
-items, like in @samp{12:00 today}. The string @samp{this} also has
-the meaning of a zero-valued time displacement, but is preferred in
-date strings like @samp{this thursday}.
-
-When a relative item causes the resulting date to cross a boundary
-where the clocks were adjusted, typically for daylight saving time,
-the resulting date and time are adjusted accordingly.
-
-The fuzz in units can cause problems with relative items. For
-example, @samp{2003-07-31 -1 month} might evaluate to 2003-07-01,
-because 2003-06-31 is an invalid date. To determine the previous
-month more reliably, you can ask for the month before the 15th of the
-current month. For example:
-
-@example
-$ date -R
-Thu, 31 Jul 2003 13:02:39 -0700
-$ date --date='-1 month' +'Last month was %B?'
-Last month was July?
-$ date --date="$(date +%Y-%m-15) -1 month" +'Last month was %B!'
-Last month was June!
-@end example
-
-Also, take care when manipulating dates around clock changes such as
-daylight saving leaps. In a few cases these have added or subtracted
-as much as 24 hours from the clock, so it is often wise to adopt
-universal time by setting the @env{TZ} environment variable to
-@samp{UTC0} before embarking on calendrical calculations.
-
-@node Pure numbers in date strings
-@section Pure numbers in date strings
-
-@cindex pure numbers in date strings
-
-The precise interpretation of a pure decimal number depends
-on the context in the date string.
-
-If the decimal number is of the form @var{yyyy}@var{mm}@var{dd} and no
-other calendar date item (@pxref{Calendar date items}) appears before it
-in the date string, then @var{yyyy} is read as the year, @var{mm} as the
-month number and @var{dd} as the day of the month, for the specified
-calendar date.
-
-If the decimal number is of the form @var{hh}@var{mm} and no other time
-of day item appears before it in the date string, then @var{hh} is read
-as the hour of the day and @var{mm} as the minute of the hour, for the
-specified time of day. @var{mm} can also be omitted.
-
-If both a calendar date and a time of day appear to the left of a number
-in the date string, but no relative item, then the number overrides the
-year.
-
-
-@node Seconds since the Epoch
-@section Seconds since the Epoch
-
-If you precede a number with @samp{@@}, it represents an internal time
-stamp as a count of seconds. The number can contain an internal
-decimal point (either @samp{.} or @samp{,}); any excess precision not
-supported by the internal representation is truncated toward minus
-infinity. Such a number cannot be combined with any other date
-item, as it specifies a complete time stamp.
-
-@cindex beginning of time, for @acronym{POSIX}
-@cindex epoch, for @acronym{POSIX}
-Internally, computer times are represented as a count of seconds since
-an epoch---a well-defined point of time. On @acronym{GNU} and
-@acronym{POSIX} systems, the epoch is 1970-01-01 00:00:00 @sc{utc}, so
-@samp{@@0} represents this time, @samp{@@1} represents 1970-01-01
-00:00:01 @sc{utc}, and so forth. @acronym{GNU} and most other
-@acronym{POSIX}-compliant systems support such times as an extension
-to @acronym{POSIX}, using negative counts, so that @samp{@@-1}
-represents 1969-12-31 23:59:59 @sc{utc}.
-
-Traditional Unix systems count seconds with 32-bit two's-complement
-integers and can represent times from 1901-12-13 20:45:52 through
-2038-01-19 03:14:07 @sc{utc}. More modern systems use 64-bit counts
-of seconds with nanosecond subcounts, and can represent all the times
-in the known lifetime of the universe to a resolution of 1 nanosecond.
-
-On most hosts, these counts ignore the presence of leap seconds.
-For example, on most hosts @samp{@@915148799} represents 1998-12-31
-23:59:59 @sc{utc}, @samp{@@915148800} represents 1999-01-01 00:00:00
-@sc{utc}, and there is no way to represent the intervening leap second
-1998-12-31 23:59:60 @sc{utc}.
-
-@node Specifying time zone rules
-@section Specifying time zone rules
-
-@vindex TZ
-Normally, dates are interpreted using the rules of the current time
-zone, which in turn are specified by the @env{TZ} environment
-variable, or by a system default if @env{TZ} is not set. To specify a
-different set of default time zone rules that apply just to one date,
-start the date with a string of the form @samp{TZ="@var{rule}"}. The
-two quote characters (@samp{"}) must be present in the date, and any
-quotes or backslashes within @var{rule} must be escaped by a
-backslash.
-
-For example, with the @acronym{GNU} @command{date} command you can
-answer the question ``What time is it in New York when a Paris clock
-shows 6:30am on October 31, 2004?'' by using a date beginning with
-@samp{TZ="Europe/Paris"} as shown in the following shell transcript:
-
-@example
-$ export TZ="America/New_York"
-$ date --date='TZ="Europe/Paris" 2004-10-31 06:30'
-Sun Oct 31 01:30:00 EDT 2004
-@end example
-
-In this example, the @option{--date} operand begins with its own
-@env{TZ} setting, so the rest of that operand is processed according
-to @samp{Europe/Paris} rules, treating the string @samp{2004-10-31
-06:30} as if it were in Paris. However, since the output of the
-@command{date} command is processed according to the overall time zone
-rules, it uses New York time. (Paris was normally six hours ahead of
-New York in 2004, but this example refers to a brief Halloween period
-when the gap was five hours.)
-
-A @env{TZ} value is a rule that typically names a location in the
-@uref{http://www.twinsun.com/tz/tz-link.htm, @samp{tz} database}.
-A recent catalog of location names appears in the
-@uref{http://twiki.org/cgi-bin/xtra/tzdate, TWiki Date and Time
-Gateway}. A few non-@acronym{GNU} hosts require a colon before a
-location name in a @env{TZ} setting, e.g.,
-@samp{TZ=":America/New_York"}.
-
-The @samp{tz} database includes a wide variety of locations ranging
-from @samp{Arctic/Longyearbyen} to @samp{Antarctica/South_Pole}, but
-if you are at sea and have your own private time zone, or if you are
-using a non-@acronym{GNU} host that does not support the @samp{tz}
-database, you may need to use a @acronym{POSIX} rule instead. Simple
-@acronym{POSIX} rules like @samp{UTC0} specify a time zone without
-daylight saving time; other rules can specify simple daylight saving
-regimes. @xref{TZ Variable,, Specifying the Time Zone with @code{TZ},

+Our units of temporal measurement, from seconds on up to months, are so
+complicated, asymmetrical and disjunctive so as to make coherent mental
+reckoning in time all but impossible. Indeed, had some tyrannical god
+contrived to enslave our minds to time, to make it all but impossible
+for us to escape subjection to sodden routines and unpleasant surprises,
+he could hardly have done better than handing down our present system.
+It is like a set of trapezoidal building blocks, with no vertical or
+horizontal surfaces, like a language in which the simplest thought
+demands ornate constructions, useless particles and lengthy
+circumlocutions. Unlike the more successful patterns of language and
+science, which enable us to face experience boldly or at least
+level-headedly, our system of temporal calculation silently and

+
+@cindex items in date strings
+A @dfn{date} is a string, possibly empty, containing many items
+separated by whitespace. The whitespace may be omitted when no
+ambiguity arises. The empty string means the beginning of today (i.e.,
+midnight). Order of the items is immaterial. A date string may contain
+many flavors of items:
+
+@itemize @bullet
+@item calendar date items
+@item time of day items
+@item time zone items
+@item day of the week items
+@item relative items
+@item pure numbers.
+@end itemize
+
+@noindent We describe each of these item types in turn, below.
+
+@cindex numbers, written-out
+@cindex ordinal numbers
+@findex first @r{in date strings}
+@findex next @r{in date strings}
+@findex last @r{in date strings}
+A few ordinal numbers may be written out in words in some contexts. This is
+most useful for specifying day of the week items or relative items (see
+below). Among the most commonly used ordinal numbers, the word
+@samp{last} stands for @math{-1}, @samp{this} stands for 0, and
+@samp{first} and @samp{next} both stand for 1. Because the word
+@samp{second} stands for the unit of time there is no way to write the
+ordinal number 2, but for convenience @samp{third} stands for 3,
+@samp{fourth} for 4, @samp{fifth} for 5,
+@samp{sixth} for 6, @samp{seventh} for 7, @samp{eighth} for 8,
+@samp{ninth} for 9, @samp{tenth} for 10, @samp{eleventh} for 11 and
+@samp{twelfth} for 12.
+
+@cindex months, written-out
+When a month is written this way, it is still considered to be written
+numerically, instead of being ``spelled in full''; this changes the
+allowed strings.
+
+@cindex language, in dates
+In the current implementation, only English is supported for words and
+abbreviations like @samp{AM}, @samp{DST}, @samp{EST}, @samp{first},
+@samp{January}, @samp{Sunday}, @samp{tomorrow}, and @samp{year}.
+
+@cindex language, in dates
+@cindex time zone item
+The output of the @command{date} command
+is not always acceptable as a date string,
+not only because of the language problem, but also because there is no
+standard meaning for time zone items like @samp{IST}. When using
+@command{date} to generate a date string intended to be parsed later,
+specify a date format that is independent of language and that does not
+use time zone items other than @samp{UTC} and @samp{Z}. Here are some
+ways to do this:
+
+@example
+$ LC_ALL=C TZ=UTC0 date
+Mon Mar 1 00:21:42 UTC 2004
+$ TZ=UTC0 date +'%Y-%m-%d %H:%M:%SZ'
+2004-03-01 00:21:42Z
+$ date --iso-8601=ns | tr T ' ' # --iso-8601 is a GNU extension.
+2004-02-29 16:21:42,692722128-0800
+$ date --rfc-2822 # a GNU extension
+Sun, 29 Feb 2004 16:21:42 -0800
+$ date +'%Y-%m-%d %H:%M:%S %z' # %z is a GNU extension.
+2004-02-29 16:21:42 -0800
+$ date +'@@%s.%N' # %s and %N are GNU extensions.
+@@1078100502.692722128
+@end example
+
+@cindex case, ignored in dates
+@cindex comments, in dates
+Alphabetic case is completely ignored in dates. Comments may be introduced
+between round parentheses, as long as included parentheses are properly
+nested. Hyphens not followed by a digit are currently ignored. Leading
+zeros on numbers are ignored.
+
+Invalid dates like @samp{2005-02-29} or times like @samp{24:00} are
+rejected. In the typical case of a host that does not support leap
+seconds, a time like @samp{23:59:60} is rejected even if it
+corresponds to a valid leap second.
+
+
+@node Calendar date items
+@section Calendar date items
+
+@cindex calendar date item
+
+A @dfn{calendar date item} specifies a day of the year. It is
+specified differently, depending on whether the month is specified
+numerically or literally. All these strings specify the same calendar date:
+
+@example
+1972-09-24 # @sc{iso} 8601.
+72-9-24 # Assume 19xx for 69 through 99,
+ # 20xx for 00 through 68.
+72-09-24 # Leading zeros are ignored.
+9/24/72 # Common U.S. writing.
+24 September 1972
+24 Sept 72 # September has a special abbreviation.
+24 Sep 72 # Three-letter abbreviations always allowed.
+Sep 24, 1972
+24-sep-72
+24sep72
+@end example
+
+The year can also be omitted. In this case, the last specified year is
+used, or the current year if none. For example:
+
+@example
+9/24
+sep 24
+@end example
+
+Here are the rules.
+
+@cindex @sc{iso} 8601 date format
+@cindex date format, @sc{iso} 8601
+For numeric months, the @sc{iso} 8601 format
+@samp{@var{year}-@var{month}-@var{day}} is allowed, where @var{year} is
+any positive number, @var{month} is a number between 01 and 12, and
+@var{day} is a number between 01 and 31. A leading zero must be present
+if a number is less than ten. If @var{year} is 68 or smaller, then 2000
+is added to it; otherwise, if @var{year} is less than 100,
+then 1900 is added to it. The construct
+@samp{@var{month}/@var{day}/@var{year}}, popular in the United States,
+is accepted. Also @samp{@var{month}/@var{day}}, omitting the year.
+
+@cindex month names in date strings
+@cindex abbreviations for months
+Literal months may be spelled out in full: @samp{January},
+@samp{February}, @samp{March}, @samp{April}, @samp{May}, @samp{June},
+@samp{July}, @samp{August}, @samp{September}, @samp{October},
+@samp{November} or @samp{December}. Literal months may be abbreviated
+to their first three letters, possibly followed by an abbreviating dot.
+It is also permitted to write @samp{Sept} instead of @samp{September}.
+
+When months are written literally, the calendar date may be given as any
+of the following:
+
+@example
+@var{day} @var{month} @var{year}

+@cindex time of day item
+
+A @dfn{time of day item} in date strings specifies the time on a given
+day. Here are some examples, all of which represent the same time:
+
+@example
+20:02:00.000000
+20:02
+8:02pm
+20:02-0500 # In @sc{est} (U.S. Eastern Standard Time).
+@end example
+
+More generally, the time of day may be given as
+@samp{@var{hour}:@var{minute}:@var{second}}, where @var{hour} is
+a number between 0 and 23, @var{minute} is a number between 0 and
+59, and @var{second} is a number between 0 and 59 possibly followed by
+@samp{.} or @samp{,} and a fraction containing one or more digits.
+Alternatively,
+@samp{:@var{second}} can be omitted, in which case it is taken to
+be zero. On the rare hosts that support leap seconds, @var{second}
+may be 60.
+
+@findex am @r{in date strings}
+@findex pm @r{in date strings}
+@findex midnight @r{in date strings}
+@findex noon @r{in date strings}
+If the time is followed by @samp{am} or @samp{pm} (or @samp{a.m.}
+or @samp{p.m.}), @var{hour} is restricted to run from 1 to 12, and
+@samp{:@var{minute}} may be omitted (taken to be zero). @samp{am}
+indicates the first half of the day, @samp{pm} indicates the second
+half of the day. In this notation, 12 is the predecessor of 1:
+midnight is @samp{12am} while noon is @samp{12pm}.
+(This is the zero-oriented interpretation of @samp{12am} and @samp{12pm},
+as opposed to the old tradition derived from Latin
+which uses @samp{12m} for noon and @samp{12pm} for midnight.)
+
+@cindex time zone correction
+@cindex minutes, time zone correction by
+The time may alternatively be followed by a time zone correction,
+expressed as @samp{@var{s}@var{hh}@var{mm}}, where @var{s} is @samp{+}
+or @samp{-}, @var{hh} is a number of zone hours and @var{mm} is a number
+of zone minutes.
+The zone minutes term, @var{mm}, may be omitted, in which case
+the one- or two-digit correction is interpreted as a number of hours.
+You can also separate @var{hh} from @var{mm} with a colon.
+When a time zone correction is given this way, it
+forces interpretation of the time relative to
+Coordinated Universal Time (@sc{utc}), overriding any previous
+specification for the time zone or the local time zone. For example,
+@samp{+0530} and @samp{+05:30} both stand for the time zone 5.5 hours
+ahead of @sc{utc} (e.g., India).
+This is the best way to
+specify a time zone correction by fractional parts of an hour.
+The maximum zone correction is 24 hours.
+
+Either @samp{am}/@samp{pm} or a time zone correction may be specified,
+but not both.
+
+
+@node Time zone items
+@section Time zone items
+
+@cindex time zone item
+
+A @dfn{time zone item} specifies an international time zone, indicated
+by a small set of letters, e.g., @samp{UTC} or @samp{Z}
+for Coordinated Universal
+Time. Any included periods are ignored. By following a
+non-daylight-saving time zone by the string @samp{DST} in a separate
+word (that is, separated by some white space), the corresponding
+daylight saving time zone may be specified.
+Alternatively, a non-daylight-saving time zone can be followed by a
+time zone correction, to add the two values. This is normally done
+only for @samp{UTC}; for example, @samp{UTC+05:30} is equivalent to
+@samp{+05:30}.
+
+Time zone items other than @samp{UTC} and @samp{Z}
+are obsolescent and are not recommended, because they
+are ambiguous; for example, @samp{EST} has a different meaning in
+Australia than in the United States. Instead, it's better to use
+unambiguous numeric time zone corrections like @samp{-0500}, as
+described in the previous section.
+
+If neither a time zone item nor a time zone correction is supplied,
+time stamps are interpreted using the rules of the default time zone
+(@pxref{Specifying time zone rules}).
+
+
+@node Day of week items
+@section Day of week items
+
+@cindex day of week item
+
+The explicit mention of a day of the week will forward the date
+(only if necessary) to reach that day of the week in the future.
+
+Days of the week may be spelled out in full: @samp{Sunday},
+@samp{Monday}, @samp{Tuesday}, @samp{Wednesday}, @samp{Thursday},
+@samp{Friday} or @samp{Saturday}. Days may be abbreviated to their
+first three letters, optionally followed by a period. The special
+abbreviations @samp{Tues} for @samp{Tuesday}, @samp{Wednes} for
+@samp{Wednesday} and @samp{Thur} or @samp{Thurs} for @samp{Thursday} are
+also allowed.
+
+@findex next @var{day}
+@findex last @var{day}
+A number may precede a day of the week item to move forward
+supplementary weeks. It is best used in expression like @samp{third
+monday}. In this context, @samp{last @var{day}} or @samp{next
+@var{day}} is also acceptable; they move one week before or after
+the day that @var{day} by itself would represent.
+
+A comma following a day of the week item is ignored.
+
+
+@node Relative items in date strings
+@section Relative items in date strings
+
+@cindex relative items in date strings
+@cindex displacement of dates
+
+@dfn{Relative items} adjust a date (or the current date if none) forward
+or backward. The effects of relative items accumulate. Here are some
+examples:
+
+@example
+1 year
+1 year ago
+3 years
+2 days
+@end example
+
+@findex year @r{in date strings}
+@findex month @r{in date strings}
+@findex fortnight @r{in date strings}
+@findex week @r{in date strings}
+@findex day @r{in date strings}
+@findex hour @r{in date strings}
+@findex minute @r{in date strings}
+The unit of time displacement may be selected by the string @samp{year}
+or @samp{month} for moving by whole years or months. These are fuzzy
+units, as years and months are not all of equal duration. More precise
+units are @samp{fortnight} which is worth 14 days, @samp{week} worth 7
+days, @samp{day} worth 24 hours, @samp{hour} worth 60 minutes,
+@samp{minute} or @samp{min} worth 60 seconds, and @samp{second} or
+@samp{sec} worth one second. An @samp{s} suffix on these units is
+accepted and ignored.
+
+@findex ago @r{in date strings}
+The unit of time may be preceded by a multiplier, given as an optionally
+signed number. Unsigned numbers are taken as positively signed. No
+number at all implies 1 for a multiplier. Following a relative item by
+the string @samp{ago} is equivalent to preceding the unit by a
+multiplier with value @math{-1}.
+
+@findex day @r{in date strings}
+@findex tomorrow @r{in date strings}
+@findex yesterday @r{in date strings}
+The string @samp{tomorrow} is worth one day in the future (equivalent
+to @samp{day}), the string @samp{yesterday} is worth
+one day in the past (equivalent to @samp{day ago}).
+
+@findex now @r{in date strings}
+@findex today @r{in date strings}
+@findex this @r{in date strings}
+The strings @samp{now} or @samp{today} are relative items corresponding
+to zero-valued time displacement, these strings come from the fact
+a zero-valued time displacement represents the current time when not
+otherwise changed by previous items. They may be used to stress other
+items, like in @samp{12:00 today}. The string @samp{this} also has
+the meaning of a zero-valued time displacement, but is preferred in
+date strings like @samp{this thursday}.
+
+When a relative item causes the resulting date to cross a boundary
+where the clocks were adjusted, typically for daylight saving time,
+the resulting date and time are adjusted accordingly.
+
+The fuzz in units can cause problems with relative items. For
+example, @samp{2003-07-31 -1 month} might evaluate to 2003-07-01,
+because 2003-06-31 is an invalid date. To determine the previous
+month more reliably, you can ask for the month before the 15th of the
+current month. For example:
+
+@example
+$ date -R
+Thu, 31 Jul 2003 13:02:39 -0700
+$ date --date='-1 month' +'Last month was %B?'
+Last month was July?
+$ date --date="$(date +%Y-%m-15) -1 month" +'Last month was %B!'
+Last month was June!
+@end example
+
+Also, take care when manipulating dates around clock changes such as
+daylight saving leaps. In a few cases these have added or subtracted
+as much as 24 hours from the clock, so it is often wise to adopt
+universal time by setting the @env{TZ} environment variable to
+@samp{UTC0} before embarking on calendrical calculations.
+
+@node Pure numbers in date strings
+@section Pure numbers in date strings
+
+@cindex pure numbers in date strings
+
+The precise interpretation of a pure decimal number depends
+on the context in the date string.
+
+If the decimal number is of the form @var{yyyy}@var{mm}@var{dd} and no
+other calendar date item (@pxref{Calendar date items}) appears before it
+in the date string, then @var{yyyy} is read as the year, @var{mm} as the
+month number and @var{dd} as the day of the month, for the specified
+calendar date.
+
+If the decimal number is of the form @var{hh}@var{mm} and no other time
+of day item appears before it in the date string, then @var{hh} is read
+as the hour of the day and @var{mm} as the minute of the hour, for the
+specified time of day. @var{mm} can also be omitted.
+
+If both a calendar date and a time of day appear to the left of a number
+in the date string, but no relative item, then the number overrides the
+year.
+
+
+@node Seconds since the Epoch
+@section Seconds since the Epoch
+
+If you precede a number with @samp{@@}, it represents an internal time
+stamp as a count of seconds. The number can contain an internal
+decimal point (either @samp{.} or @samp{,}); any excess precision not
+supported by the internal representation is truncated toward minus
+infinity. Such a number cannot be combined with any other date
+item, as it specifies a complete time stamp.
+
+@cindex beginning of time, for @acronym{POSIX}
+@cindex epoch, for @acronym{POSIX}
+Internally, computer times are represented as a count of seconds since
+an epoch---a well-defined point of time. On @acronym{GNU} and
+@acronym{POSIX} systems, the epoch is 1970-01-01 00:00:00 @sc{utc}, so
+@samp{@@0} represents this time, @samp{@@1} represents 1970-01-01
+00:00:01 @sc{utc}, and so forth. @acronym{GNU} and most other
+@acronym{POSIX}-compliant systems support such times as an extension
+to @acronym{POSIX}, using negative counts, so that @samp{@@-1}
+represents 1969-12-31 23:59:59 @sc{utc}.
+
+Traditional Unix systems count seconds with 32-bit two's-complement
+integers and can represent times from 1901-12-13 20:45:52 through
+2038-01-19 03:14:07 @sc{utc}. More modern systems use 64-bit counts
+of seconds with nanosecond subcounts, and can represent all the times
+in the known lifetime of the universe to a resolution of 1 nanosecond.
+
+On most hosts, these counts ignore the presence of leap seconds.
+For example, on most hosts @samp{@@915148799} represents 1998-12-31
+23:59:59 @sc{utc}, @samp{@@915148800} represents 1999-01-01 00:00:00
+@sc{utc}, and there is no way to represent the intervening leap second
+1998-12-31 23:59:60 @sc{utc}.
+
+@node Specifying time zone rules
+@section Specifying time zone rules
+
+@vindex TZ
+Normally, dates are interpreted using the rules of the current time
+zone, which in turn are specified by the @env{TZ} environment
+variable, or by a system default if @env{TZ} is not set. To specify a
+different set of default time zone rules that apply just to one date,
+start the date with a string of the form @samp{TZ="@var{rule}"}. The
+two quote characters (@samp{"}) must be present in the date, and any
+quotes or backslashes within @var{rule} must be escaped by a
+backslash.
+
+For example, with the @acronym{GNU} @command{date} command you can
+answer the question ``What time is it in New York when a Paris clock
+shows 6:30am on October 31, 2004?'' by using a date beginning with
+@samp{TZ="Europe/Paris"} as shown in the following shell transcript:
+
+@example
+$ export TZ="America/New_York"
+$ date --date='TZ="Europe/Paris" 2004-10-31 06:30'
+Sun Oct 31 01:30:00 EDT 2004
+@end example
+
+In this example, the @option{--date} operand begins with its own
+@env{TZ} setting, so the rest of that operand is processed according
+to @samp{Europe/Paris} rules, treating the string @samp{2004-10-31
+06:30} as if it were in Paris. However, since the output of the
+@command{date} command is processed according to the overall time zone
+rules, it uses New York time. (Paris was normally six hours ahead of
+New York in 2004, but this example refers to a brief Halloween period
+when the gap was five hours.)
+
+A @env{TZ} value is a rule that typically names a location in the
+@uref{http://www.twinsun.com/tz/tz-link.htm, @samp{tz} database}.
+A recent catalog of location names appears in the
+@uref{http://twiki.org/cgi-bin/xtra/tzdate, TWiki Date and Time
+Gateway}. A few non-@acronym{GNU} hosts require a colon before a
+location name in a @env{TZ} setting, e.g.,
+@samp{TZ=":America/New_York"}.
+
+The @samp{tz} database includes a wide variety of locations ranging
+from @samp{Arctic/Longyearbyen} to @samp{Antarctica/South_Pole}, but
+if you are at sea and have your own private time zone, or if you are
+using a non-@acronym{GNU} host that does not support the @samp{tz}
+database, you may need to use a @acronym{POSIX} rule instead. Simple
+@acronym{POSIX} rules like @samp{UTC0} specify a time zone without
+daylight saving time; other rules can specify simple daylight saving
+regimes. @xref{TZ Variable,, Specifying the Time Zone with @code{TZ},

+avoid a conflict with the alternative Posix function @code{getdate},
+and a later rename to @code{parse_datetime}. The Posix function
+@code{getdate} can parse more locale-specific dates using
+@code{strptime}, but relies on an environment variable and external

Regex provides three groups of functions with which you can operate on

-but not completely compatible with the other two, namely the @sc{posix}

We wrote this chapter with programmers in mind, not users of
programs---such as Emacs---that use Regex. We describe the Regex
In any particular syntax for regular expressions, some characters are
always special, others are sometimes special, and others are never
special. The particular syntax that Regex recognizes for a given
-regular expression depends on the value in the @code{syntax} field of
-the pattern buffer of that regular expression.
+regular expression depends on the current syntax (as set by
+@code{re_set_syntax}) when the pattern buffer of that regular expression
+was compiled.
You get a pattern buffer by compiling a regular expression. @xref{GNU
-Pattern Buffers}, and @ref{POSIX Pattern Buffers}, for more information
-on pattern buffers. @xref{GNU Regular Expression Compiling}, @ref{POSIX
+Pattern Buffers}, for more information on pattern buffers. @xref{GNU
Regular Expression Compiling}, and @ref{BSD Regular Expression
Compiling}, for more information on compiling.
-Regex considers the value of the @code{syntax} field to be a collection
-of bits; we refer to these bits as @dfn{syntax bits}. In most cases,
-they affect what characters represent what operators. We describe the
-meanings of the operators to which we refer in @ref{Common Operators},

For reference, here is the complete list of syntax bits, in alphabetical
order:
it is the beginning of a valid interval and the syntax bit
@code{RE_INTERVALS} is set.
+@cnindex RE_CONTEXT_INVALID_DUP
+@item RE_CONTEXT_INVALID_DUP
+If this bit is set, then an open-interval operator cannot occur at the
+start of a regular expression, or immediately after an alternation,
+open-group or close-interval operator.
+
@cnindex RE_CONTEXT_INVALID_OPS
@item RE_CONTEXT_INVALID_OPS
If this bit is set, then repetition and alternation operators can't be
Whether or not they will in fact be operators in certain positions
depends on other syntax bits.
+@cnindex RE_DEBUG
+@item RE_DEBUG
+If this bit is set, and the regex library was compiled with
+@code{-DDEBUG}, then internal debugging is turned on; if unset, then
+it is turned off.
+
@cnindex RE_DOT_NEWLINE
@item RE_DOT_NEWLINE
If this bit is set, then the match-any-character operator matches
If this bit is set, then the match-any-character operator doesn't match
a null character; if this bit isn't set, then it does.
+@cnindex RE_HAT_LISTS_NOT_NEWLINE
+@item RE_HAT_LISTS_NOT_NEWLINE
+If this bit is set, nonmatching lists @samp{[^...]} do not match
+newline; if not set, they do.
+
+@cnindex RE_ICASE
+@item RE_ICASE
+If this bit is set, then ignore case when matching; otherwise, case is
+significant.
+
@cnindex RE_INTERVALS
@item RE_INTERVALS
If this bit is set, then Regex recognizes interval operators; if this bit
isn't set, then it doesn't.
+@cnindex RE_INVALID_INTERVAL_ORD
+@item RE_INVALID_INTERVAL_ORD
+If this bit is set, a syntactically invalid interval is treated as a
+string of ordinary characters. For example, the extended regular
+expression @samp{a@{1} is treated as @samp{a\@{1}.
+
@cnindex RE_LIMITED_OPS
@item RE_LIMITED_OPS
If this bit is set, then Regex doesn't recognize the match-one-or-more,
point collates lower than its starting point is invalid; if this bit
isn't set, then Regex considers such a range to be empty.

+@item RE_NO_GNU_OPS
+If this bit is set, GNU regex operators are not recognized; otherwise,
+they are.
+
+@cnindex RE_NO_POSIX_BACKTRACKING
+@item RE_NO_POSIX_BACKTRACKING
+If this bit is set, succeed as soon as we match the whole pattern,
+without further backtracking. This means that a match may not be
+the leftmost longest; @pxref{What Gets Matched?} for what this means.
+
+@cnindex RE_NO_SUB
+@item RE_NO_SUB
+If this bit is set, then @code{no_sub} will be set to one during
+@code{re_compile_pattern}. This causes matching and searching routines
+not to record substring match information.

-If the syntax bit @code{RE_NO_EMPTY_ALTS} is set, then if either of the regular

-
-@itemize @bullet

-be first or last in a regular expression;

surrounding regular expressions. (Put another way, it has the lowest
precedence of any regular expression operator.)

then it would be content to match just @samp{fooqbar}.

+The @code{start} and @code{end} arrays are allocated in one of two ways.
The simplest and perhaps most useful is to let the matcher (re)allocate
enough space to record information for all the groups in the regular
-expression. If @code{regs_allocated} is @code{REGS_UNALLOCATED},
-@vindex REGS_UNALLOCATED
-the matcher allocates @math{1 + @var{re_nsub}} (another field in the
-pattern buffer; @pxref{GNU Pattern Buffers}). The extra element is set
-to @math{-1}, and sets @code{regs_allocated} to @code{REGS_REALLOCATE}.
-@vindex REGS_REALLOCATE
-Then on subsequent calls with the same pattern buffer and @var{regs}
-arguments, the matcher reallocates more space if necessary.
-
-It would perhaps be more logical to make the @code{regs_allocated} field
-part of the @code{re_registers} structure, instead of part of the
-pattern buffer. But in that case the caller would be forced to
-initialize the structure before passing it. Much existing code doesn't
-do this initialization, and it's arguably better to avoid it anyway.
-
-@code{re_compile_pattern} sets @code{regs_allocated} to
-@code{REGS_UNALLOCATED},
-so if you use the GNU regular expression
-functions, you get this behavior by default.
-
-xx document re_set_registers
-
-@sc{posix}, on the other hand, requires a different interface: the
-caller is supposed to pass in a fixed-length array which the matcher
-fills. Therefore, if @code{regs_allocated} is @code{REGS_FIXED}
-@vindex REGS_FIXED
-the matcher simply fills that array.
+expression. If @code{re_set_registers} is not called before searching
+or matching, then the matcher allocates two arrays each of @math{1 +
+@var{re_nsub}} elements (@var{re_nsub} is another field in the pattern
+buffer; @pxref{GNU Pattern Buffers}). The extra element is set to
+@math{-1}. Then on subsequent calls with the same pattern buffer and
+@var{regs} arguments, the matcher reallocates more space if necessary.
+
+The function:
+
+@findex re_set_registers
+@example
+void
+re_set_registers (struct re_pattern_buffer *@var{buffer},
+ struct re_registers *@var{regs},
+ size_t @var{num_regs},
+ regoff_t *@var{starts}, regoff_t *@var{ends})
+@end example
+
+@noindent sets @var{regs} to hold @var{num_regs} registers, storing
+them in @var{starts} and @var{ends}. Subsequent matches using
+@var{buffer} and @var{regs} will use this memory for recording
+register information. @var{starts} and @var{ends} must be allocated
+with malloc, and must each be at least @math{@var{num_regs} *
+@code{sizeof (regoff_t)}} bytes long.
+
+If @var{num_regs} is zero, then subsequent matches should allocate
+their own register data.
+
+Unless this function is called, the first search or match using
+@var{buffer} will allocate its own register data, without freeing the
+old data.
The following examples illustrate the information recorded in the
@code{re_registers} structure. (In all of them, @samp{(} represents the
open-group and @samp{)} the close-group operator. The first character
in the string @var{string} is at index 0.)

If the regular expression has an @w{@var{i}-th}

@code{@w{@var{regs}->}start[@var{i}]} to the index in @var{string} where
the substring matched by the @w{@var{i}-th} group begins, and

-@subsection POSIX Matching
-
-Matching the @sc{posix} way means trying to match a null-terminated
-string starting at its first character. Once you've compiled a pattern
-into a pattern buffer (@pxref{POSIX Regular Expression Compiling}), you
-can ask the matcher to match that pattern against a string using:
-
-@findex regexec
-@example
-int
-regexec (const regex_t *@var{preg}, const char *@var{string},
- size_t @var{nmatch}, regmatch_t @var{pmatch}[], int @var{eflags})
-@end example
-
-@noindent
-@var{preg} is the address of a pattern buffer for a compiled pattern.
-@var{string} is the string you want to match.
-
-@xref{Using Byte Offsets}, for an explanation of @var{pmatch}. If you
-pass zero for @var{nmatch} or you compiled @var{preg} with the
-compilation flag @code{REG_NOSUB} set, then @code{regexec} will ignore
-@var{pmatch}; otherwise, you must allocate it to have at least
-@var{nmatch} elements. @code{regexec} will record @var{nmatch} byte
-offsets in @var{pmatch}, and set to @math{-1} any unused elements up to
-@math{@var{pmatch}@code{[@var{nmatch}]} - 1}.
-
-@var{eflags} specifies @dfn{execution flags}---namely, the two bits
-@code{REG_NOTBOL} and @code{REG_NOTEOL} (defined in @file{regex.h}). If
-you set @code{REG_NOTBOL}, then the match-beginning-of-line operator
-(@pxref{Match-beginning-of-line Operator}) always fails to match.
-This lets you match against pieces of a line, as you would need to if,
-say, searching for repeated instances of a given pattern in a line; it
-would work correctly for patterns both with and without
-match-beginning-of-line operators. @code{REG_NOTEOL} works analogously
-for the match-end-of-line operator (@pxref{Match-end-of-line
-Operator}); it exists for symmetry.
-
-@code{regexec} tries to find a match for @var{preg} in @var{string}
-according to the syntax in @var{preg}'s @code{syntax} field.
-(@xref{POSIX Regular Expression Compiling}, for how to set it.) The
-function returns zero if the compiled pattern matches @var{string} and
-@code{REG_NOMATCH} (defined in @file{regex.h}) if it doesn't.
-
-@node Reporting Errors
-@subsection Reporting Errors
-
-If either @code{regcomp} or @code{regexec} fail, they return a nonzero
-error code, the possibilities for which are defined in @file{regex.h}.
-@xref{POSIX Regular Expression Compiling}, and @ref{POSIX Matching}, for
-what these codes mean. To get an error string corresponding to these
-codes, you can use:
-
-@findex regerror
-@example
-size_t
-regerror (int @var{errcode},
- const regex_t *@var{preg},
- char *@var{errbuf},
- size_t @var{errbuf_size})
-@end example
-
-@noindent
-@var{errcode} is an error code, @var{preg} is the address of the pattern
-buffer which provoked the error, @var{errbuf} is the error buffer, and
-@var{errbuf_size} is @var{errbuf}'s size.
-
-@code{regerror} returns the size in bytes of the error string
-corresponding to @var{errcode} (including its terminating null). If
-@var{errbuf} and @var{errbuf_size} are nonzero, it also returns in
-@var{errbuf} the first @math{@var{errbuf_size} - 1} characters of the
-error string, followed by a null.
-@var{errbuf_size} must be a nonnegative number less than or equal to the
-size in bytes of @var{errbuf}.
-
-You can call @code{regerror} with a null @var{errbuf} and a zero
-@var{errbuf_size} to determine how large @var{errbuf} need be to
-accommodate @code{regerror}'s error string.
-
-@node Using Byte Offsets
-@subsection Using Byte Offsets
-
-In @sc{posix}, variables of type @code{regmatch_t} hold analogous
-information, but are not identical to, @sc{gnu}'s registers (@pxref{Using

-@code{regexec} a nonzero @var{pmatch} of type @code{regmatch_t}, i.e.,
-the address of a structure of this type, defined in
-@file{regex.h}:
-
-@tindex regmatch_t

+dnl gives unlimited permission to copy and/or distribute it,

+
+dnl From Bruno Haible and Sam Steingold.
+
+dnl Sets the HOST_CPU_C_ABI variable to the canonical name of the CPU with its
+dnl C language ABI (application binary interface).
+dnl Also defines __${HOST_CPU_C_ABI}__ as a C macro in config.h.
+dnl
+dnl This canonical name can be used to select a particular assembly language
+dnl source file that will interoperate with C code on the given host.
+dnl
+dnl For example:
+dnl * 'i386' and 'sparc' are different canonical names, because code for i386
+dnl will not run on SPARC CPUs and vice versa. They have different
+dnl instruction sets.
+dnl * 'sparc' and 'sparc64' are different canonical names, because code for
+dnl 'sparc' and code for 'sparc64' cannot be linked together: 'sparc' code
+dnl contains 32-bit instructions, whereas 'sparc64' code contains 64-bit
+dnl instructions. A process on a SPARC CPU can be in 32-bit mode or in 64-bit
+dnl mode, but not both.
+dnl * 'mips' and 'mipsn32' are different canonical names, because they use
+dnl different argument passing and return conventions for C functions, and
+dnl although the instruction set of 'mips' is a large subset of the
+dnl instruction set of 'mipsn32'.
+dnl * 'mipsn32' and 'mips64' are different canonical names, because they use
+dnl different sizes for the C types like 'int' and 'void *', and although
+dnl the instruction sets of 'mipsn32' and 'mips64' are the same.
+dnl * 'arm' and 'armel' are different canonical names, because they use
+dnl different memory ordering for the C types like 'int', and although
+dnl the instruction sets of 'arm' and 'armel' are the same.
+dnl * The same name 'i386' is used for CPUs of type i386, i486, i586
+dnl (Pentium), AMD K7, Pentium II, Pentium IV, etc., because
+dnl - Instructions that do not exist on all of these CPUs (cmpxchg,
+dnl MMX, SSE, SSE2, 3DNow! etc.) are not frequently used. If your
+dnl assembly language source files use such instructions, you will
+dnl need to make the distinction.
+dnl - Speed of execution of the common instruction set is reasonable across
+dnl the entire family of CPUs. If you have assembly language source files
+dnl that are optimized for particular CPU types (like GNU gmp has), you
+dnl will need to make the distinction.
+dnl See <http://en.wikipedia.org/wiki/X86_instruction_listings>.
