We don't need to define @bindir@, because gtester-report never
actually referred to it. We also don't need a definition of
GTESTER_REPORT for use by GLib itself, because its last use was removed
in 2013 (https://bugzilla.gnome.org/show_bug.cgi?id=709995).

The text about deallocation of GArrays with elements containing
dynamically-allocated memory was confusing. It initially mentioned
clear_func, but later said elements with dynamically allocated memory
"should be freed separately".
Clarify this by using the same structure as g_ptr_array_free —
highlight the need to set a clear_func by consolidating the text about
it in a separate paragraph.

Previously, in the case where 'kf' has more than one ref, calling
g_key_file_free(kf) would break it. For example, calling
g_key_file_has_key(kf, ...) would hit the following assertion:
g_hash_table_lookup: assertion 'hash_table != NULL' failed
This is because g_key_file_free() calls g_key_file_clear() which sets
self->groups and other fields to NULL; most lookup functions assume
these fields are non-NULL.
One fix would be to call g_key_file_init() right after
g_key_file_clear() in g_key_file_free(). However, in the case where
there are no other refs to the keyfile, this would mean allocating
many new hash tables which will be immediately destroyed when
g_key_file_unref() removes the last ref. Instead, inline the unref, and
re-initialize the internal state when the keyfile is still alive.
1) Creating a directory with 0666 does not prevent
traversal on Windows (ACL determines the possibility
of traversal, and Windows mkdir() does not translate
permission bits into ACL). Don't do the traversal check on Windows.
2) Creating a file with 0555 also isn't translated into
read-only ACL, Windows sets the read-only attribute instead,
which blocks all changes, including changes to file times.
Add the write permissions on Windows before changing file times.
It turns out that UCRT (which is the C runtime that Visual Studio
uses by default these days) quietly changed the semantics for
stat() functions and its variants. Previously they provided data
for the symlink (if the file queried was a symlink), now they
provide data for the target of the symlink.
glib used to call _wstat64() to get certain stat-ish data about
files, such as st_dev, since it was deemed that computing that
data in glib using custom code would be pointless, as _wstat64()
worked just fine.
With UCRT this is no longer true. This commit drops _wstat64() in
favour of a bunch of custom calls that populate the stat buffer
manually. This way glib correctly gets information about a symlink,
not its target.
The _fstat64() call is still being used, as it does not suffer
from this problem and thus remains untouched.
GMarkup is not to be used for untrusted input. It’s always been designed
for parsing application-provided data files, not random stuff sent to
you by an attacker.

Even if we're using a prime modulo for the initial probe, our table is
power-of-two-sized, meaning we can set the mask simply by subtracting one
from the size.
Sequential integers would be densely packed in the table, leaving the
high-index buckets unused and causing abnormally long probes for many
operations. This was especially noticeable with failed lookups and
when "aging" the table by repeatedly inserting and removing integers
from a narrow range using g_direct_hash() as the hashing function.
The solution is to multiply the hash by a small prime before applying
the modulo. The compiler optimizes this to a few left shifts and adds, so
the constant overhead is small, and the entries will be spread out,
yielding a lower average probe count.
Extended path prefix looks like "\\?\",
and NT object path prefix looks like "\??\".
Strip them only if they are followed by a character
(any character) and a colon (:), indicating that
it's a DOS path with a drive.
Otherwise stripping such prefix might result in a patch
that looks like a relative path.
For example, "\\?\Volume{GUID}\" becomes "Volume{GUID}\",
which is a valid directory name.
Currently it's up to the user to make sense of such paths.
When running a test as a subprocess and matching its output, it’s very
annoying for GLib to tell you that the output didn’t match your pattern,
*but not actually say what the output was*. Fix that.

Expands to the GNU C fallthrough statement attribute if the compiler is gcc.
This allows declaring case statement to explicitly fall through in switch
statements. To enable this feature, use -Wimplicit-fallthrough during
compilation.
It might not be immediately obvious that this is the case. Let's record
it in the description of `GTimeVal` itself and also in
`g_time_val_from_iso8601`.
We also drop an incorrect statement in the documentation for
`g_time_val_from_iso8601` stating that years up to 3000 were supported;
this is also not true for the same reason.
Related: #1509
On 32 bit systems, the size of a long might be the same as the size of
an int. In that case, we won't be able to get an overflow when
converting from a GTimeVal to a time_t. Skip the test for this in that
case.

If the given key is not found, clear the orig_key and value arguments to
NULL as well as returning FALSE. Then the caller can unconditionally
check them.
This makes the behaviour of g_hash_table_lookup_extended() consistent
with g_hash_table_steal_extended().

The goal of this commit is to reduce differences between the autotools and meson build.
With autotools AC_FUNC_ALLOCA was used which defines HAVE_ALLOCA_H, HAVE_ALLOCA,
C_ALLOCA. meson tried to replicate that with has_function() but alloca can be a macro
and and is named _alloca under Windows. Since we require a working alloca anyway
and only need to know if the header exists replace AC_FUNC_ALLOCA with a simple
AC_CHECK_HEADERS.
There is still one user of HAVE_ALLOCA in the embedded gnulib, but since alloca is
always provided through galloca.h just force define HAVE_ALLOCA there and add a comment.
The docs were mentioning alloca as an example for cross compiling. Since that variable no
longer exists now replace it with another one.
The new typeof() macro version of g_clear_pointer() was evaluating its
pointer argument more than once, meaning any side effects would be
evaluated multiple times.
The existing (other) macro version of g_clear_pointer() was evaluating
its argument exactly once. This mismatch could have confused people or
lead to subtle bugs.

These functions may be OK to leave the G_GNUC_MALLOC attribute on,
because the only valid pointers in the storage areas they return are,
themselves, new pointers.
However, it’s a lot easier to remove the attributes now than to try and
diagnose miscompilations in future. The performance impact of this is
likely to be unmeasurable. If there are performance problems caused by
this, then they can be profiled and fixed case-by-case in future,
bearing in mind the possibility for miscompilation if G_GNUC_MALLOC is
readded.

Thanks to some great investigation by Benjamin Moody, it’s clear that
our documentation and usage of G_GNUC_MALLOC has fallen behind GCC’s
interpretation of the malloc attribute, meaning that recent versions of
GCC could miscompile code which uses G_GNUC_MALLOC incorrectly.
Update the documentation of G_GNUC_MALLOC to match the current GCC
documentation (for GCC 8.2). Following commits will drop our use of
G_GNUC_MALLOC from inappropriate functions.
Specifically, the change in GCC’s interpretation of the malloc attribute
which could cause miscompilation is that returned storage areas are now
assumed to not contain valid pointers — so realloc() cannot have the
malloc attribute, and neither can a function which returns a newly
allocated structure with fields initialised to other pointers.

haven’t called abort() since about 2011, when commit
a04efe6afb63d54e12ff8f329cbaf458a2e31b26 changed the logic to use
SIGTRAP to make it possible to skip past fatal log messages in the
