+ * pwd/fgetpwent.c: Don't include ../nss/nss_files/files-parse.c to
+ define parse_line function.
+ (parse_line): #define to _nss_files_parse_pwent and
+ add extern decl for that.
+
+ * nss/nss_files/files-XXX.c (internal_getent): Return
+ NSS_STATUS_TRYAGAIN for ERANGE error.
+
+ * sysdeps/i386/strtok.S (LreturnNULL): Save current state ptr instead
+ of null, so next round returns null again instead of bombing. Fix
+ from drepper.
+
+ * nss/nss_files/files-parse.c (LINE_PARSER): Take new first arg EOLSET.
+ Remove ; after `ENTDATA_DECL (data)'.
+ Truncate line at strpbrk (line, EOLSET "\n").
+ (ENTDATA_DECL): Put ; at end.
+ (MIDLINE_COMMENTS): Macro removed.
+ * nss/nss_files/files-ethers.c: Pass new argument.

+ * nss/nss_files/files-pwd.c: Get parse_line with extern decl, since
+ fgetpwent.c already defines it.
+ * nss/nss_files/files-grp.c: Likewise.
+
+ * elf/dl-load.c (_dl_map_object): Use any object with matching l_name
+ as well as any matching with l_libname. Fix DT_SONAME lookup to use
+ string table properly.
+
+ * elf/rtld.c (dl_main): Set _dl_rtld_map.l_name from _dl_argv[0] when
+ invoked directly, and l_libname from that if PT_INTERP missing.
+ Set l_name from l_libname only if not set from argv.
+
+ * time/europe, time/northamerica: Updated from ADO 96i.

+# From Paul Eggert (1996-06-12):
+# Summer Time was first seriously proposed by William Willett (1857-1915),
+# a London builder who circulated a pamphlet ``Waste of Daylight'' (1907)
+# that proposed advancing clocks 20 minutes on each of four Sundays in April,
+# and retarding them by the same amount on four Sundays in September.
+# A bill was drafted in 1909 and introduced in Parliament several times,
+# but it met with ridicule and opposition, especially from farming interests.
+# One-hour Summer Time was eventually adopted as a wartime measure in 1916.
+
# From Arthur David Olson (January 19, 1989):
#
# A source at the British Information Office in New York avers that it's
# who provided the wartime regulations and a snippet of Hansard explaining
# why double summer time started on a Monday in 1945 (it was Easter).
+# From Peter Ilieve <peter@aldie.co.uk> (1996-05-29):
+# I have now got a copy of the British Standard Time Act 1968.
+# It says (S4(2)) that it expires at 02:00 GMT on 31 October 1971 unless
+# an Order in Council was passed in Parliament to make the Act permanent.
+# No Order was passed, so 02:00 1971-10-31 it is...
+#
+# Interestingly, it says baldly `This Act shall come into force on
+# 27 October 1968', without giving a time. As S1 of the Act merely
+# stated that `The time for general purposes in the United Kingdom
+# (to be known as British standard time) shall be one hour in
+# advance of Greenwich mean time throughout the year; ...' you could
+# possibly argue that the start time of BStandardT was 00:00 1968-10-27,
+# especially as the Act repealed the Summer Time Acts 1916--1947 in toto,
+# thereby destroying the authority of the Summer Time Order specifying
+# summer time in 1968....
+
# From Peter Ilieve <peter@memex.co.uk> (November 18, 1993)
#
# Here is a revised version of my tabrules file for the perl script I sent
# To maintain strict historical accuracy you could start a new UK ending rule
# of Oct Sun>=22 in 1990.
-# From Paul Eggert <eggert@twinsun.com> (November 18, 1993):
+# From Paul Eggert <eggert@twinsun.com> (1996-06-12):
#
# As Ilieve remarks, the date `20 April 1924' in the table of ``Summer Time: A
# Consultation Document'' (Cm 722, 1989) table is a transcription error;
# It actually just had one transition.
# * Northern Ireland used single daylight savings time throughout WW II.
# Actually, it conformed to Britain.
+# * GB-Eire changed standard time to 1 hour ahead of GMT on 1968-02-18.
+# Actually, that date saw the usual switch to summer time.
+# Standard time was not changed until 1968-10-27 (the clocks didn't change).
#
-# The following claim by Shanks is possible though doubtful;
-# we'll ignore it for now.
+# The following claims by Shanks are possible though doubtful;
+# we'll ignore them for now.
# * Jersey, Guernsey, and the Isle of Man did not switch from GMT
# to daylight savings time until 1921 Apr 3, when they began to
# conform with Great Britain.
+# * Dublin's 1971-10-31 switch was at 02:00, even though London's was 03:00.
+#
#
# Whitman says Dublin Mean Time was -0:25:21, which is more precise than Shanks.
+# From an anonymous contributor (1996-06-02):
+# The law governing time in Ireland is under Statutory Instrument SI 395/94,
+# which gives force to European Union 7th Council Directive # 94/21/EC.
+# Under this directive, the Minister for Justice in Ireland makes appropriate
+# regulations. I spoke this morning with the Secretary of the Department of

+# From Paul Eggert (1996-06-12):
+# Daylight Saving Time was first suggested as a joke by Benjamin Franklin
+# in his whimsical essay ``Turkey vs Eagle, McCauley is my Beagle'' (1784).
+# Not everyone is happy with the results:
+#
+# I don't really care how time is reckoned so long as there is some
+# agreement about it, but I object to being told that I am saving
+# daylight when my reason tells me that I am doing nothing of the kind.
+# I even object to the implication that I am wasting something
+# valuable if I stay in bed after the sun has risen. As an admirer
+# of moonlight I resent the bossy insistence of those who want to
+# reduce my time for enjoying it. At the back of the Daylight Saving
+# scheme I detect the bony, blue-fingered hand of Puritanism, eager
+# to push people into bed earlier, and get them up earlier, to make
+# them healthy, wealthy and wise in spite of themselves.
+#
+# -- Robertson Davies, The Diary of Samuel Marchbanks (1947), XIX, Sunday
+
# From Arthur David Olson:
# US Daylight Saving Time ended on the last Sunday of *October* in 1974.
# See, for example, the front page of the Saturday, October 26, 1974
# Canada
-# Canada is reportedly lots easier than the US--leastways since 1951.
-# I don't know what they did before then.
-# 4.3BSD claims that it's perfectly regular.
-# According to a posting in "comp.bugs.misc", "comp.unix.wizards", etc.
-# on February 8, 1987, by Dave Sherman of the Law Society of Upper Canada,
-# "...Canada (well, Ontario and at least some of the other provinces) are
-# adopting the new daylight savings time rules...". We assume all of
-# Canada is doing so.

-# From Bob Devine (January 28, 1988):
-# All of Canada did have DST from your first rule except Saskatchewan.
-# Which parts did not observe DST is hard to pinpoint but most of the
-# province follows the rules.
-# NOTE: those that didn't have DST for that rule, also
-# probably did not have it for several years previous.
-
-# From U. S. Naval Observatory (January 19, 1989):
-# CANADA NEW FDL 3.5H BEHIND UTC ST.JOHN'S
-# CANADA NEW FDL 1.5H BEHIND UTC APR 3 - OCT 29
-# CANADA ATLANTIC 4 H BEHIND UTC HALIFAX
-# CANADA ATLANTIC 3 H BEHIND UTC APR 3 - OCT 29

-# CANADA PACIFIC 8 H BEHIND UTC VANCOUVER
-# CANADA PACIFIC 7 H BEHIND UTC APR 3 - OCT 29
-# CANADA YUKON SAME AS PACIFIC DAWSON
-
-# From Arthur David Olson (January 21, 1989):
-# April 3 fell on a Sunday in 1988; October 29 fell on a Sunday in 1989. Ahem.
-# Note claim that there's double DST in Newfoundland and that Yukon should
-# be same as Pacific.
-
-# From W. Jones (jones@skdad.usask.ca) (November 6, 1992):
-# The. . .below is based on information I got from our law library, the
-# provincial archives, and the provincial Community Services department.
-# A precise history would require digging through newspaper archives, and
-# since you didn't say what you wanted, I didn't bother.
-#
-# Saskatchewan is split by a time zone meridian (105W) and over the years
-# the boundary became pretty ragged as communities near it reevaluated
-# their affiliations in one direction or the other. In 1965 a provincial
-# referendum favoured legislating common time practices.
-#
-# On 15 April 1966 the Time Act (c. T-14, Revised Statutes of
-# Saskatchewan 1978) was proclaimed, and established that the eastern
-# part of Saskatchewan would use CST year round, that districts in
-# northwest Saskatchewan would by default follow CST but could opt to
-# follow Mountain Time rules (thus 1 hour difference in the winter and
-# zero in the summer), and that districts in southwest Saskatchewan would
-# by default follow MT but could opt to follow CST.
-#
-# It took a few years for the dust to settle (I know one story of a town
-# on one time zone having its school in another, such that a mom had to
-# serve her family lunch in two shifts), but presently it seems that only
-# a few towns on the border with Alberta (e.g. Lloydminster) follow MT
-# rules any more; all other districts appear to have used CST year round
-# since sometime in the 1960s.
-#
-# Here's how I would summarize things. Establish a "Saskatchewan" CST
-# time zone, and note that it officially exists as of 15 April 1966. Any
-# current exceptions can put themselves in the "Mountain" zone, since
-# those are the rules they follow. Any past exceptions can be forgotten,
-# since that's what those who live here have done.
-
-# From Arthur David Olson (November 21, 1992):
-# East-Saskatchewan kept to avoid problems for folks using that zone by name;
-# plain Saskatchewan added.
-
# From Alain LaBont<e'> <ALB@immedia.ca> (1994-11-14):
# I post here the time zone abbreviations standardized in Canada
# for both English and French in the CAN/CSA-Z234.4-89 standard....
# From Paul Eggert <eggert@twinsun.com> (1994-11-22):
# Alas, this sort of thing must be handled by localization software.
