The output of the %p type is implementation defined and on Windows we get
leading zeros depending on the pointer type size. Instead of adding
ifdeffery use g_snprintf() to generate the expected message.

g_steal_pointer is both an inline function, returning gpointer, and a
macro that casts the return value to the type of its argument. The first
version of the macro uses '0 ? (*(pp)) : (g_steal_pointer) (pp)' to cast
the return value to the type of *pp, but this fails to yield warnings
about incompatible pointer types with current gcc. Apparently the
ternary operator is optimized away before the type of the expression is
determined.
The typeof() (or __typeof__()) operator allows an explicit cast.

Previous version of this function started with a call to g_utf8_to_utf16(),
which also served as a NULL check, since g_utf8_to_utf16() just returns NULL
on NULL strings. Current version of this function does some filename string
checks first and converts it to utf16 only after these checks are done, and
these checks do not take into account the possibility of filename being NULL.
Fix this by explicitly checking for NULL.
- Compiler checks were failing because it were using C compiler to build
objc code.
- xdgmime is needed on osx too.
- -DGIO_COMPILATION must be passed to objc compiler too.
- gapplication doesn't build on osx, it is excluded in autotools too.
We have to be careful when we use add_project_link_arguments(): All
targets are built using link arguments for the C language, except for
libgio on osx which use the objc language, because it contains some ".m"
source files. See https://github.com/mesonbuild/meson/issues/3585.
https://bugzilla.gnome.org/show_bug.cgi?id=796214
Those files got renamed to .c to work around an automake issue, but
Meson needs them to have .m extension. Better rename them at build time
in Makefile.am since that's where the workaround is needed.

Some compilers, particularly Android on armv5 and old versions of Clang
provide atomic ops, but don't define __GCC_HAVE_SYNC_COMPARE_AND_SWAP_4
so we need to define it ourselves.
This matches what configure does, with the exception that now it's only
done for Android since clang defines __GCC_HAVE_SYNC_COMPARE_AND_SWAP_4
now.
https://bugzilla.gnome.org/show_bug.cgi?id=796325
The latest patches have fixed the atomic check, which
uses __sync_bool_compare_and_swap , and thus fails on
MSVC.
As a result, in gatomic.c, we ended up trying to include
pthread.h, which failed.
This mimics the old behaviour a bit more closely, where
G_ATOMIC_LOCK_FREE was always defined in the win32
glibconfig.h

The 'no-builtin' checks were just plain wrong. For accurate detection of
functions, use has_function with a header in the prefix. This fixes
posix_memalign detection on Android and on MinGW32, MSYS-MinGW-w64, and
old versions of MSYS2-MinGW-w64.
Using the header in the `prefix:` is generally a good idea because of
how macOS does targetting of specific macOS releases at compile time.
This also allows cross-files to override the result by setting
`has_function_stpcpy = false`, etc in [extra properties]

The comment stated that the test isn't good enough, but it correctly
detects a C99 printf when I build with -D__USE_MINGW_ANSI_STDIO=1
and an incompatible printf without it.
Using mingw-w64 from current MSYS2.
https://bugzilla.gnome.org/show_bug.cgi?id=795569
The current docs implied, by using the printf name, that the macros would
be compatible with printf(), but that's not always the case.
On Windows we use gnulib if the system printf isn't good enough.
This can happen on MinGW without __USE_MINGW_ANSI_STDIO set or with MSVC
with a varrying degree of incompatibility.

Commit 3e96523e6b did not entirely fix the test, as the compiled test
code did not have a main() function, so failed to link with:
/usr/lib/gcc/x86_64-redhat-linux/7/../../../../lib64/crt1.o: In function `_start':

collect2: error: ld returned 1 exit status
This caused an invalid mixtures of builtin and non-builtin atomics/locks

This allows building with posix threads on Windows. It is generally

GVfsUDisks2VolumeMonitor handles x-gvfs-hide/x-gvfs-show mount options
used to overwrite our heuristics whether the mount should be shown, or
hidden. Unfortunately, it works currently only for mounts with
corresponding fstab entries, because the options are read over
g_unix_mount_point_get_options. Let's introduce g_unix_mount_get_options
to allow reading of the options for all sort of mounts (e.g. created
over pam_mount, or manually mounted).

__MINGW32__ is defined on all MinGW variants including MinGW-w64.
__MINGW64_VERSION_MAJOR is only defined on MinGW-w64.
This difference is important because on MinGW-w64 we must #include
winternl.h because including ntdef.h results in compiler errors
about symbol redefinition, and the header warns that it is deprecated
and may be removed in the future.

Do not add support for its subtypes, since all their constructors return
GParamSpec*, and g_param_spec_unref() takes a GParamSpec* rather than a
gpointer — adding G_DEFINE_AUTOPTR_CLEANUP_FUNC() for subtypes of
GParamSpec results in compiler warnings about mismatched parameter
types (GParamSpecBoolean* vs GParamSpec*, for example).

If using g_ptr_array_remove*() with a non-NULL GDestroyNotify function,
the value returned will probably be freed memory (depending on what the
GDestroyNotify) function actually does. Warn about that in the
documentation. We can’t just unconditionally return NULL in these cases,
though, since the user might have set the GDestroyNotify to a nifty
function which doesn’t actually free the element; so returning it might
still be valid and useful.
Also add missing (nullable) annotations to that documentation.

The -fstack-protector-strong used in many distributions by default has a
rather drastic slowdown of the fast path in generated _get_type()
functions using G_DEFINE_* macros. The amount can vary by architecture,
GCC version, and compiler flags.
To work around this, and ensure a higher probability that our fast-path
will match what we had previously, we need to break out the slow-path
(registering the type) into a secondary function that is not a candidate
for inlining.
This ensures that the common case (type registered, return the GType id)
is the hot path and handled in the prologue of the generated assembly even
when -fstack-protector-strong is enabled.
