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.

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.

Now liblzma.pc can be relocatable only if using CMake >= 3.20
but that should be OK as now we shouldn't get broken liblzma.pc
if CMAKE_INSTALL_LIBDIR or CMAKE_INSTALL_INCLUDEDIR contain an
absolute path.
Thanks to Eli Schwartz.

On E2K the function compiles only due to compiler emulation but the
function is never used. It's cleaner to omit the function when it's
not needed even though it's a "static inline" function.
Thanks to Ilya Kurdyukov.

There is no need to make a similar change in configure.ac.
With Autoconf 2.72, the deprecated macro AC_PROG_CC_C99
is an alias for AC_PROG_CC which prefers a C11 compiler.

A similar one was already there for CRC64 but nowadays also CRC32
has a CLMUL implementation, so it's good to test it better too.

GCC 4.2 doesn't have __builtin_bswap16() and friends so tuklib_integer.h
tries to use OS-specific byte swap methods instead. On OpenBSD those
macros are swap16/32/64 instead of bswap16/32/64 like on other *BSDs
and Darwin.
An alternative to "#ifdef __OpenBSD__" could be "#ifdef swap16" as it
is a macro. But since OpenBSD seems to be a special case under this
special case of "*BSDs and Darwin", checking for __OpenBSD__ seems
the more conservative choice now.
Thanks to Christian Weisgerber and Brad Smith who both submitted
the same patch a few hours apart.

liblzma_VERSION has never existed in the repository. xz_VERSION from
the project() command was used for liblzma SOVERSION so use xz_VERSION
here too.
The wrong variable did no harm in practice as PROJECT_VERSION
was used as the fallback. It has the same value as xz_VERSION.

This is a mess because liblzma DLL outside Cygwin and MSYS2
is liblzma.dll instead of lzma.dll to avoid a conflict with
lzma.dll from LZMA SDK.
On Cygwin the name was "liblzma-5.dll" while "cyglzma-5.dll"
would have been correct (and match what Libtool produces).
MSYS2 likely was broken too as it uses the "msys-" prefix.
This change has no effect with MinGW-w64 because with that
the "lib" prefix was correct already.
With MSVC builds this is a small breaking change that requires developers
to adjust the library name when linking against liblzma. The liblzma.dll
name is kept as is but the import library and static library are now
lzma.lib instead of liblzma.lib. This is helpful when using pkgconf
because "pkgconf --msvc-syntax --libs liblzma" outputs "lzma.lib"
(it's converted from "-llzma" in liblzma.pc). It would be easy to
keep the liblzma.lib naming but the pkgconf compatibility seems worth
it in the long run. The lzma.lib name is compatible with MinGW-w64
too as -llzma will find also lzma.lib.
vcpkg had been patching CMakeLists.txt this way since 2022 but I
learned this only recently. The reasoning for the patch makes sense,
and while this is a small breaking change with MSVC, it seems like
a decent compromise as it keeps the DLL name the same.
2022 patch in vcpkg: 0707a17ecf/ports/liblzma/win_output_name.patch
See the discussion: https://github.com/microsoft/vcpkg/pull/39024
Thanks to Vincent Torri for confirming the naming issue on Cygwin.

The ancient /bin/tr on Solaris doesn't support '\n'.
With /usr/xpg4/bin/tr it works but it might not be in PATH.
Another problem was that sed was given input that didn't have a newline
at the end. Text files must end with a newline to be portable.
Fix both problems:
- Handle multiline input within sed itself to avoid one tr invocation.
The default sed even on Solaris does understand \n.
- Use octals in tr -d. \012 works for ASCII "line feed", it's even
used as an example in the Solaris man page. But we must strip
also ASCII "carriage return" \015 and EBCDIC "next line" \025.
The EBCDIC case got handled with \n previously. Stripping \012
and \015 on EBCDIC system won't matter as those control chars
won't be present in the string in the first place.
An awk-based solution could be an alternative but it might need
special casing on Solaris to used nawk instead of awk. The changes
in this commit are smaller and should have a smaller risk for
regressions. It's also possible that version.sh will be dropped
entirely at some point.

There's no real value in doing it via commit for official GH actions. We
can keep using pinned commits for unofficial actions. It's hassle for no
gain.
Maybe going forward we can limit this further by only being paranoid
for the jobs with any access to tokens.

Solaris' GCC can't understand that our use is fine, unlike modern compilers:
```
list.c: In function 'print_totals_basic':
list.c:1191:4: error: format not a string literal, argument types not checked [-Werror=format-nonliteral]
uint64_to_str(totals.files, 0));
^~~~~~~~~~~~~
cc1: all warnings being treated as errors
```
It's presumably because of older gettext missing format attributes.
This is with `gcc (GCC) 7.3.0`.

In the past this wasn't done before releases; the Git repository
just contained the files from the Translation Project. But this
way it is clearer when comparing release tarballs against the
Git repository. In future releases this might no longer be necessary
within a stable branch as the .po files won't change so easily anymore
when creating a tarball.
When po/xz.pot doesn't exist, running "make" or "make dist" will
create it. Then the .po files will be updated but only if they
actually would change more than the POT-Creation-Date line.
Then the .gmo files would be generated from the .po files.
This is the case before and after this commit.
However, "make dist" and thus "make mydist" did a forced update
to the files, updating them even if the only change was the
POT-Creation-Date line. This had pros and cons: It made it clear
that the .po file really is in sync with the recent strings in
the package. On the other hand, it added noise in form of changed
files in the source tree and distribution tarballs. It can be
ignored with something like "diff -I'^"POT-Creation-Date: '" but
it's still a minor annoyance *if* there's not enough value in
having the most recent timestamp.
Setting DIST_DEPENDS_ON_UPDATE_PO = no means that such forced
update won't happen in "make dist" anymore. However, the "mydist"
target will use xz.pot-update target which is the same target that
is run when xz.pot doesn't exist at all yet. Thus "mydist" will
ensure that the translations are up to date, without noise from
changes that would affect only the POT-Creation-Date line.
Note that po4a always uses msgmerge with --update, so POT-Creation-Date
in the man page translations is never the only change in .po files.
In that sense this commit makes the message translations behave more
similarly to the man page translations.
Distribution tarballs will still have non-reproducible POT-Creation-Date
in po/xz.pot and po4a/xz-man.pot but those are just two files. Even they
could be made reproducible from a Git timestamp if desired.
(cherry picked from commit 9284f1aea3)
The .po files from the Translation Project come with unwrapped
strings so this matches it.
This may reduce the noise in diffs too. When the beginning of
a paragraph had changed, the rest of the lines got rewrapped
in msgsid. Now it's just one very long line that changes when
a paragraph has been edited.
The --add-location=file option was removed as redundant. The line
numbers don't exist in the .pot file due to --porefs file and thus
they cannot get copied to the .po files either.
(cherry picked from commit 4beba1cd62)
This way the PO file diffs are less noisy but the locations of the
strings are still present at file level, just without line numbers.
The option is available since gettext 0.19 (2014).
configure.ac requires 0.19.6.
(cherry picked from commit fccebe2b4f)
Since the source strings have changed, these would get marked as
fuzzy and the original string would be used instead. The original
and translated strings are identical in this case so it wouldn't
matter. But patching the translations helps still because then
po4a will show the correct translation percentage.

One has to pass -DENABLE_X86_ASM=ON to cmake to enable the
CRC assembly code. Autodetection isn't done. Looking at
CMAKE_SYSTEM_PROCESSOR might not work as it comes from uname
unless cross-compilation is done using a CMake toolchain file.
On top of this, if the code is run on modern processors that support
the CLMUL instruction, then the C code should be faster (but then
one should also be using a x86-64 build if possible).
