+Subject: [PATCH 52/N] Cygwin: try to avoid recalling offline files
+
+Chances are high that Cygwin recalls offline files from remote
+storage, even if the file is only accessed during stat(2) or
+readdir(3).
+
+To avoid this
+- make sure Cygwin is placeholder-aware,
+- open files in path_conv handling, as well as in stat(2)/readdir(3)
+  scenarios with FILE_OPEN_NO_RECALL, and
+- during symlink checking or testing for executablility, don't even
+  try to open the file if one of the OFFLINE attributes is set.

+Subject: [PATCH 55/N] Cygwin: console: Fix exit code for non-cygwin process.
+
+If non-cygwin process is executed in console, the exit code is not
+set correctly. This is because the stub process for non-cygwin app
+crashes in fhandler_console::set_disable_master_thread() due to NULL
+pointer dereference. This bug was introduced by the commit:
+3721a756b0d8 ("Cygwin: console: Make the console accessible from
+other terminals."), that the pointer cons is accessed before fixing
+when it is NULL. This patch fixes the issue.

+Subject: [PATCH 61/N] Avoid sharing cygheaps across Cygwin versions
+
+It frequently leads to problems when trying, say, to call from MSYS2's
+Bash into Cygwin's or Git for Windows', merely because sharing that data
+is pretty finicky.
+
+For example, using the MSYS2' Bash using the MSYS2 runtime version that
+is current at time of writing, trying to call Cygwin's programs fails
+in manners like this:
+
+    $ /c/cygwin64/bin/uname -r
+      0 [main] uname (9540) child_copy: cygheap read copy failed, 0x800000000..0x800010BE0, done 0, windows pid 9540, Win32 error 6
+    680 [main] uname 880 C:\cygwin64\bin\uname.exe: *** fatal error - couldn't create signal pipe, Win32 error 5
+
+with the rather misleading exit code 127 (a code which is reserved to
+indicate that a command was not found).
+
+Let's just treat the MSYS2 runtime and the Cygwin runtime as completely
+incompatible with one another, by virtue of using a different
+magic constant than merely `CHILD_INFO_MAGIC`.
+
+By using the msys2-runtime commit to modify that magic constant, we can
+even spawn programs using a different MSYS2 runtime (such as Git for
+Windows') because the commit serves as the tell-tale whether two MSYS2
+runtime versions are compatible with each other. To support building in
+the MSYS2-packages repository (where we do not check out the
+`msys2-runtime` but instead check out Cygwin and apply patches on top),
+let's accept a hard-coded commit hash as `./configure` option.
+
+One consequence is that spawned MSYS processes using a different MSYS2
+runtime will not be visible as such to the parent process, i.e. they
+cannot share any resources such as pseudo terminals. But that's okay,
+they are simply treated as if they were regular Win32 programs.
+
+Note: We have to use a very rare form of encoding the brackets in the
+`expr` calls: quadrigraphs (for a thorough explanation, see
+https://www.gnu.org/savannah-checkouts/gnu/autoconf/manual/autoconf-2.70/html_node/Quadrigraphs.html#Quadrigraphs).
+This is necessary because it is apparently impossible to encode brackets
+in `configure.ac` files otherwise.

+From: Johannes Schindelin <johannes.schindelin@gmx.de>
+Date: Tue, 21 Feb 2023 16:36:36 +0100
+Subject: [PATCH 62/N] uname: report msys2-runtime commit hash, too
+
+Having just Cygwin's version in the output of `uname` is not helpful, as
+both MSYS2 as well as Git for Windows release intermediate versions of
+the MSYS2 runtime much more often than Cygwin runtime versions are
+released.
