Define NetBSD and Darwin/macOS feature test macros. Autoconf defines
these too (and a few others).
Define the macros on Windows except with MSVC. The _GNU_SOURCE macro
makes a difference with mingw-w64.
Use a function instead of a macro. Don't take the TARGET_OR_ALL argument
because there's always global effect because the global variable
CMAKE_REQUIRED_DEFINITIONS is modified.
All translators know that --command-line-options must not be translated.
With some other strings it's not obvious when the untranslated string
must be preserved. These comments hopefully help.
The deprecated aliases are lzcmp, lzdiff, lzless, lzmore,
lzgrep, lzegrep, and lzfgrep. The commands that start with
the xz prefix have identical behavior, for example, both
lzgrep and xzgrep handle all supported file formats.
This doesn't affect lzma, unlzma, lzcat, lzmadec, or lzmainfo.
The last release of LZMA Utils was made in 2008, but the lzma
compatibility alias for the gzip-like tool is still in common use.
Deprecating it would cause unnecessary breakage.
Nowaways $(top_builddir)/lib/getopt.h depends on headers in
$(top_srcdir)/lib, so both have to be in the include path.
CMake-based build already did this.

Now one can pass gl_replace_getopt=yes to configure to force the use
of GNU getopt_long from the lib directory. This only checks that the
value of gl_replace_getopt is non-empty, so one cannot force the
replacement to be disabled.

Make it clearer that translations cannot be accepted if they don't
come via the Translation Project.
Column headings have been handled automatically for years and now --help
is autowrapped too, so the related instructions can be removed.
Make it work for out-of-tree builds without requiring one to specify
the location of the xz executable.
Add xz --filters-help.
Make the output shorter by reducing the number of xz -lvv test files.
Show the value of LANGUAGE environment variable.
Show the xz.git version using git describe --abbrev=8 instead of =4.
Since there are no spaces between words, the unsophisticated automatic
word wrapping code needs some help. Compared to the version in the
Translation Project, I added a few \t characters which the word
wrapping code interprets as zero width spaces (hopefully they are
placed correctly). These edits can be seen with this command:
grep -v ^# po/zh_TW.po | grep --color -F '\t'
Tabs have been converted to spaces and a "serial" number has been
added. The previous version was from 2008/2009. There are no functional
changes since then but now it's clearer that the copy in XZ Utils
isn't outdated.
The new file was picked from the Gnulib commit
81a4c1e3b7692e95c0806d948cbab9148ad85ef2. A later commit adds
a warranty disclaimer to the license, which obviously is fine,
but I didn't find a SPDX license identifier for the new license,
so for simplicity I used the earlier commit.
People may put -fsanitize in CC instead of CFLAGS so check both.
Landlock sandbox isn't compatible with sanitizers so it's nice
to catch the incompatible options at configure time.
Don't attempt to do the same in CMakeLists.txt; the check for
CMAKE_C_FLAGS / CFLAGS shall be enough there. The extra flags from
the CC environment variable go into the undocumented internal variable
CMAKE_C_COMPILER_ARG1 (all flags from CC go into that same variable).
Peeking the internal variable merely for improved diagnostics isn't
worth it.

The check can be skipped by passing SKIP_WERROR_CHECK=yes to configure.
It won't be documented anywhere else than in the error message.
Ways to test:
./configure CC=gcc CFLAGS=-Wunused-macros
./configure CC=clang CFLAGS=-Weverything
./configure CC=clang CFLAGS=-Weverything SKIP_WERROR_CHECK=yes
