The function declaration we use changed a bit since then.
In particular, some arguments became const. See following commit.

It’s landed in kernel 5.9: http://lkml.iu.edu/hypermail/linux/kernel/2008.0/02649.html
Note, this is untested because I currently don’t have kernel 5.9. We can
fix anything up if it breaks once the new syscall is wrapped in glibc.

This currently just implements the same functionality as the existing
`stat()`/`fstat()`/`fstatat()`/`lstat()` calls, although where a reduced
field set is requested it may return faster.

cc.has_function() provide false positive for Android-20 and earlier; the fix is in Meson 0.54.2. People attempting to cross-compile previously wouldn’t have been able to get it to work without manual intervention, so the dependency bump for this platform is not an additional obstacle for them.
In cases where performance are critical it can be useful to disable
checks and asserts. GStreamer has those options too, using the same name
and setting them yielding means we can set those options on the main
project (e.g. gst-build) and glib will inherit the same value when built
as subproject.
`get_option('buildtype')` will return `'custom'` for most combinations
of `-Doptimization` and `-Ddebug`, but those two will always be set
correctly if only `-Dbuildtype` is set. So we should look at those
options directly.
For the two-way mapping between `buildtype` and `optimization`
+ `debug`, see this table:

The test code can be built on Windows using Cygwin or MSYS2.
Even though it's test code, it might bring assertion dialog box
for native Windows while meson configure.
There were a couple of custom paths which could end up being relative,
rather than absolute, due to not properly prefixing them with
`get_option('prefix')`.
The use of `join_paths()` here correctly drops all path components
before the final absolute path in the list of arguments. So if someone
configures GLib with an absolute path for `gio_module_dir`, that will be
used unprefixed; but if someone configures with a relative path, it will
be prefixed by `get_option('prefix)`.

This is required to be able to build the doc. The debian docker is still
pinned to 0.49.2 which ensure we can build with both versions of meson.
Meson 0.52.0 warns about adding -Wall flag manually, we can remove that
because warning_level=1 (the default) option already implies it.
By default (on POSIX) we would be inheriting thread priorities from the
thread that pushed a new task on non-exclusive thread pools and causes a
new thread to be created. This can cause any non-exclusive thread pool
to accidentally contain threads of different priorities, or e.g. threads
with real-time priority.
To prevent this, custom handling for setting the scheduler settings for
Linux and Windows is added and as a fallback for other platforms a new
thread is added that is responsible for spawning threads for
non-exclusive thread pools.

It's not supported on macOS' clang compiler and will fail the visibility
check and thus make the G_GNUC_INTERNAL attribute do nothing.

Checking if "GNU C visibility attributes test" compiles: NO
When choosing the type to base `size_t` on, check the compatibility of
passing pointers, as well as the width of the type, to avoid compiler
warnings in future.
For now, the code to do the checks is fairly ugly due to limitations in
Meson. In particular, the new checks are limited to gcc and clang (other
compilers will behave as before), and they are all duplicated. See the
comments in the code for links to Meson improvement requests.

Fixes: #1777
If we're cross-compiling, the installed-tests are useful even if we
can't run them on the build machine: we can copy them to the host
machine (possibly via a distro package like Debian's libglib2.0-tests)
and run them there.
While I'm changing the build-tests condition anyway, deduplicate it.
Based on a patch by Helmut Grohne.

We already depend on Meson 0.49.2, which depends on Python 3.5, so we’ve
actually implicitly had this requirement for a while. Might as well make
it explicit.

Instead of letting each directory to find its way to link with libdl,
it is easier to put the check in the top level, so its result can be
used by all directories.
It is a follow-up of https://gitlab.gnome.org/GNOME/glib/merge_requests/810.
Also set the Windows version to be 10 or newer when targeting UWP, since
the Windows 8 SDK does not have many of the APIs we need, such as
_beginthreadex.
We cannot bump to the latest stable version of Meson, even if it would
make our life easier. We can, though, use the version of Meson shipped
by the next, soon to be released Debian stable.
We're using the `install` argument for configure_file() all over the
place.
The support for an `install` argument for configure_file() was added in
Meson 0.50, but we haven't bumped the minimum version of Meson we
require, yet; which means we're getting compatibility warnings when
using recent versions of Meson, and undefined behaviour when using older
versions.
The configure_file() object defaults to `install: false`, unless an
install directory is used. This means that all instances of an `install`
argument with an explicit `true` or `false` value can be removed,
whereas all instances of `install` with a value determined from a
configuration option must be turned into an explicit conditional.
The plugin modules in these tests get statically linked with a separate
copy of GLib so they end up calling vfuncs in their own copy of GLib.
Fixes#1648
GLib checks for __sync_bool_compare_and_swap, and requires
__GCC_HAVE_SYNC_COMPARE_AND_SWAP_4 to be defined if the function is available,
except with special cases like Linux armv5.
Extend the existing workaround to unbreak on old gcc versions that implement
__sync_bool_compare_and_swap but don't provide __GCC_HAVE_* macros.
We need to enable building the dirent and gnulib sources for clang-cl,
as we are still using the Microsoft-style headers and lib's and CRT.
We need to also do this for the following, for similar reasoning:
-Symbol export (via __declspec(dllexport))
-Dependency discovery without pkg-config files
-long long and ssize_t detection
We do, however, enable the autoptr tests for clang-cl builds. Note that
at this point real MSVC builds are still better supported than clang-cl
builds, and it will likely remain so for at least the near future,
alhtough real MSVC builds of the GTK stack are consumable and are usable
by clang-cl.
We are still seeing occasional CI failures due to timeouts when heavily
loaded. It’s best to wait a little longer than to throw all the results
out when they’re almost done.
For example, see https://gitlab.gnome.org/tristan957/glib/-/jobs/331330.

The code in gunicollate uses __STDC_ISO_10646__ to check that wchar.h is avilable,
that it includes the wide character related functions and that sizeof(wchar_t) == 4.
cygwin defines __STDC_ISO_10646__ and has sizeof(wchar_t) == 2 and the C standard text isn't
that clear on whether wchar_t should always be 4 bytes in this case, so we better not use if for
assuming the size here.
Instead of relying on __STDC_ISO_10646__ add HAVE_WCHAR_H and SIZEOF_WCHAR_T macros.
With HAVE_WCHAR_H defined we assume wchar_t exists and wchar.h exists. With SIZEOF_WCHAR_T we
guard the parts where the size of wchar_t is assumed to be 4 (currently all of them).
Note that this doesn't make the collate tests pass under cygwin, they fail before and after this patch for me.
See !755 for related discussions.
The correct spelling is "_NL_ABALTMON_n" rather than "_NL_ALTMON_n".
The typo made Meson build think that _NL_ABALTMON_n constants are
not supported which was totally wrong. This made g_date_time_format()
output incorrect abbreviated month names in some languages.
The old configure.ac script was correct here.
Bug introduced in commit be4f96b650.
Closes: #1759
Currently, there is no way to prevent tests from building using meson.
When cross-compiling, building the tests isn't necessary.
Instead, only build the tests on the following conditions:
1) If not cross-compiling.
2) If cross-compiling, and there is an exe wrapper.
Instead of requiring the user to specify which option to use, which
they will not really know, nor should they need to know.
Search for each type of iconv (in the C library, as a separate
native library, as the GNU implementation) by default.

Add a missing ifdef from gfileutils.c that is needed for O_BINARY.
The other option was to remove O_BINARY, but i left it there for
the sake of completeness, as this is what g_file_get_contents() uses.
Instead of hardcoding /proc/self/cmdline use for __linux__ only,
do a configure-time test for it.
Specifically, this enables /proc/self/cmdline use on Cygwin.
The configure-time test is very primitive (just tests that the
file exists and that it's possible to read more than one byte from it),
relying on the testsuite for more extensive checks.
The test in the testsuite is modified to always run, even on platforms
where it isn't supposed to pass. If it fails there, the testing framework
skips it. If the test unexpectedly passes, that is reported too.
