 <p>Windows XP is not a supported platform, but all newer Windows should be able to build the JDK.</p>
 <p>On Windows, it is important that you pay attention to the instructions in the <a href="#special-considerations">Special Considerations</a>.</p>
-<p>Windows is the only non-POSIX OS supported by the JDK, and as such, requires some extra care. A POSIX support layer is required to build on Windows. Currently, the only supported such layer is Cygwin. (Msys is no longer supported due to a too old bash; msys2 and the new Windows Subsystem for Linux (WSL) would likely be possible to support in a future version but that would require effort to implement.)</p>
+<p>Windows is the only non-POSIX OS supported by the JDK, and as such, requires some extra care. A POSIX support layer is required to build on Windows. Currently, the only supported such layers are Cygwin and MSYS2. (MSYS is no longer supported due to an outdated bash; While OpenJDK can be built with MSYS2, support for it is still experimental, so build failures and unusual errors are not uncommon.)</p>
 <p>Internally in the build system, all paths are represented as Unix-style paths, e.g. <code>/cygdrive/c/git/jdk/Makefile</code> rather than <code>C:\git\jdk\Makefile</code>. This rule also applies to input to the build system, e.g. in arguments to <code>configure</code>. So, use <code>--with-msvcr-dll=/cygdrive/c/msvcr100.dll</code> rather than <code>--with-msvcr-dll=c:\msvcr100.dll</code>. For details on this conversion, see the section on <a href="#fixpath">Fixpath</a>.</p>
 <h4 id="cygwin">Cygwin</h4>
 <p>A functioning <a href="http://www.cygwin.com/">Cygwin</a> environment is thus required for building the JDK on Windows. If you have a 64-bit OS, we strongly recommend using the 64-bit version of Cygwin.</p>

 <h3 id="building-for-armaarch64">Building for ARM/aarch64</h3>
 <p>A common cross-compilation target is the ARM CPU. When building for ARM, it is useful to set the ABI profile. A number of pre-defined ABI profiles are available using <code>--with-abi-profile</code>: arm-vfp-sflt, arm-vfp-hflt, arm-sflt, armv5-vfp-sflt, armv6-vfp-hflt. Note that soft-float ABIs are no longer properly supported by the JDK.</p>
 <p>The JDK contains two different ports for the aarch64 platform, one is the original aarch64 port from the <a href="http://openjdk.java.net/projects/aarch64-port">AArch64 Port Project</a> and one is a 64-bit version of the Oracle contributed ARM port. When targeting aarch64, by the default the original aarch64 port is used. To select the Oracle ARM 64 port, use <code>--with-cpu-port=arm64</code>. Also set the corresponding value (<code>aarch64</code> or <code>arm64</code>) to --with-abi-profile, to ensure a consistent build.</p>

+# "Circular on Matching the Hours of Governmental and Official Circles
+# in Provinces
+# Approved 1314/03/22 [=1935-06-13]
+# According to the ruling of the Honorable Cabinet, it is ordered that from
+# now on in all internal provinces of the country, governmental and official
+# circles set their time to match Tehran time (three hours and half before
+# Greenwich)....
+#
+# I still haven't found out when Tehran itself switched to +03:30....
+#
+# From Paul Eggert (2022-06-05):
+# Although the above says Tehran was at +03:30 before 1935-06-13, we don't
+# know when it switched to +03:30.  For now, use 1935-06-13 as the switch date.
+# Although most likely wrong, we have no better info.
+
+# From Roozbeh Pournader (2022-06-01):
+# This is from Kayhan newspaper, one of the major Iranian newspapers, from
+# March 20, 1978, page 2:
+#
+# "Pull the clocks 60 minutes forward
+# As we informed before, from the fourth day of the month Farvardin of the
+# new year [=1978-03-24], clocks will be pulled forward, and people's daily
+# work and life program will start one hour earlier than the current program.
+# On the 1st day of the month Farvardin of this year [=1977-03-21], they had
+# pulled the clocks forward by one hour, but in the month of Mehr
+# [=1977-09-23], the clocks were pulled back by 30 minutes.
+# In this way, from the 4th day of the month Farvardin, clocks will be ahead
+# of the previous years by one hour and a half.
+# According to the new program, during the night of 4th of Farvardin, when
+# the midnight, meaning 24 o'clock is announced, the hands of the clock must
+# be pulled forward by one hour and thus consider midnight 1 o'clock in the
+# forenoon."
+#
+# This implies that in September 1977, when the daylight savings time was
+# done with, Iran didn't go back to +03:30, but immediately to +04:00.
+#
+#
+# This is from the major Iranian newspaper Ettela'at, dated [1978-08-03]...,
+# page 32. It looks like they decided to get the clocks back to +4:00
+# just in time for Ramadan that year:
+#
+# "Tomorrow Night, Pull the Clocks Back by One Hour
+# At 1 o'clock in the forenoon of Saturday 14 Mordad [=1978-08-05], the
+# clocks will be pulled one hour back and instead of 1 o'clock in the
+# forenoon, Radio Iran will announce 24 o'clock.
+# This decision was made in the Cabinet of Ministers meeting of 25 Tir
+# [=1978-07-16], [...]
+# At the beginning of the year 2537 [=March 1978: Iran was using a different
+# year number for a few years then, based on the Coronation of Cyrus the
+# Great], the country's official time was pulled forward by one hour and now
+# the official time is one hour and a half ahead compared to last year,
+# because in Farvardin of last year [=March 1977], the official time was
+# pulled forward one hour and this continued until the second half of last
+# year [=September 1977] until in the second half of last year the official
+# time was pulled back half an hour and that half hour still remains."
+#
+# This matches the time of the true noon published in the newspapers, as they
+# clearly go from +05:00 to +04:00 after that date (which happened during a
+# long weekend in Iran).
+
+# From Roozbeh Pournader (2022-05-31):
+# [Movahedi S. Cultural preconceptions of time: Can we use operational time
+# to meddle in God's Time? Comp Stud Soc Hist. 1985;27(3):385-400]
+# https://www.jstor.org/stable/178704
+# Here's the quotes from the paper:
+# 1. '"Iran's official time keeper moved the clock one hour forward as from
+# March 22, 1977 (Farvardin 2, 2536) to make maximum use of daylight and save
+# in energy consumption. Thus Iran joined such other countries as Britain in
+# observing what is known as 'daylight saving.' The proposal was originally
+# put forward by the Ministry of Energy, in no way having any influence on
+# observing religious ceremonies. Moving time one hour forward in summer
+# means that at 11:00 o'clock on March 21, the official time was set as
+# midnight March 22. Then September 24 will actually begin one hour later
+# than the end of September 23 [...]." Iran's time base thus continued to be
+# Greenwich Mean Time plus three and one-half hours (plus four and one-half
+# hours in summer).'
+#
+# The article sources this from Iran Almanac and Book of Facts, 1977, Tehran:
+# Echo of Iran, which is on Google Books at
+# https://www.google.com/books/edition/Iran_Almanac_and_Book_of_Facts/9ybVAAAAMAAJ.
+# (I confirmed it by searching for snippets.)
+#
+# 2. "After the fall of the shah, the revolutionary government returned to
+# daylight-saving time (DST) on 26 May 1979."
+#
+# This seems to have been announced just one day in advance, on 25 May 1979.
+#
+# The change in 1977 clearly seems to be the first daylight savings effort in
+# Iran. But the article doesn't mention what happened in 1978 (which was
+# still during the shah's government), or how things continued in 1979
+# onwards (which was during the Islamic Republic).

+# https://www.diariooficial.interior.gob.cl/versiones-anteriores/do-h/19460715/#page/1
+# The decree contemplated "[t]hat this advancement of the Official Time, even
+# though it has been proposed for the cities of Santiago and Valparaíso only,
+# must be agreed with that of other cities, due to the connection of various
+# activities that require it, such as, for example, the operation of rail
+# services".  It was originally set to expire after 30 days but was extended
+# through 1946-08-31 by Decree 4,506, dated 1946-08-13.

+# Law Number 8,522, promulgated 1946-08-27, reunified Chilean clocks at their
+# new "Summer Time" of -04, reckoned as that of "the meridian of the
+# Astronomical Observatory of Lo Espejo, advanced by 42 minutes and 45
+# seconds".  Although this law specified the new Summer Time to start on 1
+# September each year, a special "transitional article" started it a few days
+# early, as soon as the law took effect.  As the law was to take force "from
+# the date of its publication in the 'Diario Oficial', which happened the
+# following day, presume the change took place in Santiago and its environs
+# from 24:00 -03 to 23:00 -04 on Wednesday 1946-08-28.  Although this was a
+# no-op for wall clocks in the north and south of the country, put their formal
+# start to DST an hour later when they reached 24:00 -04.
+# https://www.diariooficial.interior.gob.cl/versiones-anteriores/do-h/19460828/#page/1
+# After a brief "Winter Time" stint at -05 beginning 1947-04-01, Law Number
+# 8,777, promulgated 1947-05-17, established year-round -04 "from 23:00 on the
+# second day after it is published in the 'Diario Oficial'."  It was published
+# on Monday 1947-05-19 and so took effect from Wednesday 1947-05-21 23:00.
