groff defaults to SGR escapes. Using -P-c passes -c to grotty
which restores the old behavior. Perhaps there is a better way to
get pure plain text output but this works for now.
signal.h in WASI SDK doesn't currently provide sigprocmask()
or sigset_t. liblzma doesn't need them so this change makes
liblzma and xzdec build against WASI SDK. xz doesn't build yet
and the tests don't either as tuktest needs setjmp() which
isn't (yet?) implemented in WASI SDK.

(The original commit was edited a little by Lasse Collin.)
The CMake build will try to create broken symlinks on Unix and Unix-like
platforms. Cygwin and MSYS2 are Unix-like, but may not be able to create
broken symlinks. The value of the CYGWIN or MSYS environment variables
determine if broken symlinks are valid.
The default for MSYS2 does not allow for broken symlinks, so the CMake
build has been broken for MSYS2 since commit
80a1a8bb83.
All of the MSYS2 environments need make, and it does not come with the
toolchain package. The toolchain package will install the needed
compiler toolchains since without this package CMake cannot properly
generate the Makefiles.
The default for many of the MSYS2 environments is for CMake to create
Ninja build files. This would complicate the build script since we would
need a different command to run the tests. Its simpler to always use
Unix Makefiles so that "make test" is always a usable target for
testing.
To workaround Automake lacking Windows resource compiler support, an
empty source file is compiled to overwrite the resource files for static
library builds. Translation units without an external declaration are
not allowed by the C standard and result in a warning when used with
-Wempty-translation-unit (Clang) or -pedantic (GCC).
Only a subset of the tests run by the Linux and MacOS Autotools builds
are run. The most interesting tests are the ones that disable threads,
encoders, and decoders.
The Windows runner will only be run manually since these tests will
likely take much longer than the Linux and MacOS runners. This runner
should be used before merging any large features and before releases.
Currently the clang64 environment fails to due to a warning and
-Werror is enabled for the CI tests. This is still an early version
since the CMake build can be done for MSVC and optionally each of the
MSYS2 environments. GitHub does not allow manually running the CI tests
unless the workflow is checked on the default branch so checking in a
minimum version is a good idea.
Thanks to Arthur S for the original proposing the original patch.

Clang 16.0.0 and earlier have a bug that the ifunc resolver function
triggers the -Wunused-function warning. The resolver function is static
and only "used" by the __attribute__((__ifunc()__)).
At this time, the bug is still unresolved, but has been reported:
https://github.com/llvm/llvm-project/issues/63957
This is not a problem in GCC.
This further improves the documentation from commit
f36ca7982f. The previous wording of
"supported options" was slightly misleading since the options that are
printed are the ones that are relevant for encoding/decoding. It is not
about which options can or must be specified.
The new Tests section describes basic information about the tests, how
to run them, and important details when cross compiling. We have had a
few questions about how to compile the tests without running them, so
hopefully this information will help others with the same question in the
future.

The Memory limit information section described three output
columns when it actually has six. This was reworded to
"multiple" to make it more future proof.
* Moved max_block_list_size from a global to local variable.
* Reworded error message in validate_block_list_filter().
* Removed helper function filter_chain_error().
* Changed 1 << X to 1U << X in many places
The order is now consistent with the order the command line arguments
are documented earlier in the man page. The new order is:
1. --list
2. --info-memory
3. --version
Instead of the previous order:
1. --version
2. --info-memory
3. --list
