Checked the changes and they're all innocuous. This should hopefully
fix the "externally managed" pip error in these jobs that started
recently.

v5.2 didn't build with CMake. Other branches had
include(CMakePushCheckState) in top-level CMakeLists.txt
which made the build work.

IMPORTANT: This includes a security fix to command line tool
argument handling.
Some toolchains embed an application manifest by default to declare
UAC-compliance. Some also declare compatibility with Vista/8/8.1/10/11
to let the app access features newer than those of Vista.
We want all the above but also two more things:
- Declare that the app is long path aware to support paths longer
than 259 characters (this may also require a registry change).
- Force the code page to UTF-8. This allows the command line tools
to access files whose names contain characters that don't exist
in the current legacy code page (except unpaired surrogates).
The UTF-8 code page also fixes security issues in command line
argument handling which can be exploited with malicious filenames.
See the new file w32_application.manifest.comments.txt.

Thanks to Vijay Sarvepalli for reporting the issue to me.
Thanks to Kelvin Lee for testing with MSVC and helping with

Now the information in the "Details" tab in the file properties
dialog matches the naming convention of Cygwin and MSYS2. This
is only a cosmetic change.
(cherry picked from commit dad1530915)
Autotools-based build has always done this so this is for consistency.
However, the CMake build won't create the DEF file when building
for Cygwin or MSYS2 because in that context it should be useless.
(If Cygwin or MSYS2 is used to host building of normal Windows
binaries then the DEF file is still created.)

If common_w32res.rc is modified, the resource files need to be rebuilt.
In contrast, the liblzma*.map files truly are link dependencies.

The MB output can overflow with huge numbers. Most likely these are
invalid .lzma files anyway, but let's avoid garbage output.
lzmadec was adapted from LZMA Utils. The original code with this bug
was written in 2005, over 19 years ago.

Support for instruction "movzw" without suffix in "GNU as" was
added in commit [1] and stabilized in binutils 2.27, released
in August 2016. Earlier systems don't accept this instruction
without a suffix, making range_decoder.h's inline assembly
unable to build on old systems such as Ubuntu 16.04, creating
error messages like:
lzma_decoder.c: Assembler messages:
lzma_decoder.c:371: Error: no such instruction: `movzw 2(%r11),%esi'
lzma_decoder.c:373: Error: no such instruction: `movzw 4(%r11),%edi'
lzma_decoder.c:388: Error: no such instruction: `movzw 6(%r11),%edx'
lzma_decoder.c:398: Error: no such instruction: `movzw (%r11,%r14,4),%esi'
Change "movzw" to "movzwl" for compatibility.

(cherry picked from commit 6cd7c86078)
It won't be implemented. find + xargs is more flexible, for example,
it allows compressing small files in parallel. An example for that
has been included in the xz man page since 2010.

The liblzma target was recently changed to link against Threads::Threads
with the PRIVATE keyword. I had forgotten that xz itself depends on
pthreads too due to pthread_sigmask(). Thus, the build broke when
building shared liblzma and pthread_sigmask() wasn't in libc.
Thanks to Peter Seiderer for the bug report.

This addresses the issue I mentioned in
6c095a98fb and speeds up the Valgrind
job a bit, because non-xz tools aren't run unnecessarily with
Valgrind by the script tests.

It shouldn't make any difference because LIBS should be empty
at that point in configure. But prepending is the correct way
because in general the libraries being added might require other
libraries that come later on the command line.
(cherry picked from commit 2402e8a1ae)
It's more robust in case the compiler allows pre-C99 implicit function
declarations. If an x86 intrinsic is missing and gets treated as
implicit function, the linking step will very probably fail. This
isn't the only way to workaround implicit function declarations but
it might be the simplest and cleanest.
The problem hasn't been observed in the wild.
There are a couple more AC_COMPILE_IFELSE uses in configure.ac.
Of these, Landlock check calls prctl() and in theory could have
the same problem. In practice it doesn't as the check program
looks for several other things too. However, it was changed to
AC_LINK_IFELSE still to look more correct.
Similarly, m4/tuklib_cpucores.m4 and m4/tuklib_physmem.m4 were
updated although they haven't given any trouble either. They
have worked all these years because those check programs rely
on specific headers and types: if headers or types are missing,
compilation will fail. Using the linker makes these checks more
similar to the ones in cmake/tuklib_*.cmake which always link.
(cherry picked from commit 7bb46f2b7b)
AC_COMPILE_IFELSE needed -Werror because Clang <= 14 would merely
warn about the unsupported attribute and implicit function declaration.
Changing to AC_LINK_IFELSE handles the implicit declaration because
the symbol __crc32d is unlikely to exist in libc.
Note that the other part of the check is that #include <arm_acle.h>
must work. If the header is missing, most compilers give an error
and the linking step won't be attempted.
Avoiding -Werror makes the check more robust in case CFLAGS contains
warning flags that break -Werror anyway (but this isn't the only check
in configure.ac that has this problem). Using AC_LINK_IFELSE also makes
the check more similar to how it is done in CMakeLists.txt.
(cherry picked from commit 35eb57355a)
It's nice to keep these in sync. The use of main() will later allow
AC_LINK_IFELSE usage too which may avoid the more fragile -Werror.
(cherry picked from commit 5a728813c3)
I had missed this simpler method before. It does create a dependency
so that if .in.h changes the copying is done again.
(cherry picked from commit de215a0517)
It was weird to add CMAKE_THREAD_LIBS_INIT in CMAKE_REQUIRED_LIBRARIES
only if CLOCK_MONOTONIC is available. Alternative would be to remove
the thread libs from CMAKE_REQUIRED_LIBRARIES after the check for
pthread_condattr_setclock() but keeping the libs should be fine too.
Then it's ready in case more pthread functions were wanted some day.
(cherry picked from commit e620f35097)
In CMake, check_c_source_compiles() always links too. With
link-time optimization, unused functions may get omitted if
main() doesn't depend on them. Consider the following which
tries to check if somefunction() is available when <someheader.h>
has been included:
#include <someheader.h>
int foo(void) { return somefunction(); }
int main(void) { return 0; }
LTO may omit foo() completely because the program as a whole doesn't
need it and then the program will link even if the symbol somefunction
isn't available in libc or other library being linked in, and then
the test may pass when it shouldn't.
What happens if <someheader.h> doesn't declare somefunction()?
Shouldn't the test fail in the compilation phase already? It should
but many compilers don't follow the C99 and later standards that
prohibit implicit function declarations. Instead such compilers
assume that somefunction() exists, compilation succeeds (with a
warning), and then linker with LTO omits the call to somefunction().
Change the tests so that they are part of main(). If compiler accepts
implicitly declared functions, LTO cannot omit them because it has to
assume that they might have side effects and thus linking will fail.
On the other hand, if the functions/intrinsics being used are supported,
they might get optimized away but in that case it's fine because they
really are supported.
It is fine to use __attribute__((target(...))) for main(). At least
it works with GCC 4.9 to 14.1 on x86-64.

CC from environment is used to initialize CMAKE_C_COMPILER so

The syntax in ci_build.bash was broken in case one wished to put
spaces in CC.
(cherry picked from commit 0c1e6d900b)
This way pthread options aren't passed to the linker when linking
against shared liblzma but they are still passed when linking against
static liblzma. (Also, one never needs the include path of the
threading library to use liblzma since liblzma's API headers
don't #include <pthread.h>. But <pthread.h> tends to be in the
default include path so here this change makes no difference.)
One cannot mix target_link_libraries() calls that use the scope
(PRIVATE, PUBLIC, or INTERFACE) keyword and calls that don't use it.
The calls without the keyword are like PUBLIC except perhaps when
they aren't, or something like that... It seems best to always
specify a scope keyword as the meanings of those three keywords
at least are clear.
(cherry picked from commit ac05f1b0d7)
This shouldn't make much difference in practice as on Windows
no flags are needed anyway and unitialized variable (when threading
is disabled) expands to empty. But it's clearer this way.
