This was causing g_param_value_defaults to return 1
for GVariant values even when the value is clearly
different from the default.
This was showing up as gtk-builder-tool stripping
non-default values for GtkActionable::action-target
from ui files.
It was previously a copy–paste of G_VALUE_COLLECT, which is wrong,
because it’s the inverse function of G_VALUE_COLLECT. Document that, so
the whole thing is a little less confusing (but by no means perfect).

not the typedef. glib-mkenums would then attempt to read the next line

The *_init() functions have prototypes incompatible with *InitFunc types they
are being cast to. This upsets GCC 8's -Wcast-function-type that's enabled by
default with -Wextra.
Let's not have the public header files emit a warning and neutralize it by
doing a void(*)(void) cast first.

It's not possible to subclass GValue, and by always explicitly casting
here it is easy to write broken code (e.g. passing a GValue**) without
the compiler warning about that.
By not casting, the compiler will error out if anything but a GValue* is
passed here.

gtk-doc doesn’t support them any more since it was ported to Markdown,

Properly define GLIB/GOBJECT_STATIC_COMPILATION when static build is enabled.
Use library() instead of shared_library() to allow selecting static builds.
https://bugzilla.gnome.org/show_bug.cgi?id=784995
This makes easier to write a module that can be both dynamic and static.
It will allow to statically build modules from glib-networking, for
example.
A module can rename its g_io_module_load() function to
g_io_<modulename>_load(), and then an application which links statically
against that module can call g_io_<modulename>_load(NULL) to register
types and extension points from the module. If a module is loaded
dynamically, its load() function will continue to be called with a
non-NULL GIOModule instance.

Weak-pointers are currently lacking g_set_object() & g_clear_object()

Conceptually, these functions clearly ought to be fine for a const
structure. This avoids _G_TYPE_CVH (the implementation of
G_TYPE_CHECK_VALUE_TYPE, G_VALUE_HOLDS, G_VALUE_HOLDS_BOXED etc.)
needing to cast to a mutable GValue, which causes
G_VALUE_HOLDS (cv, type) to issue warnings under gcc -Wcast-qual if
cv is a const GValue *.

The type propagation breaks the GRefPtr.h class in WebKitGTK, and in
any case existing C++ code calling the C API will need to perform an

When compiling code that includes gobject.h using GCC with the ISO
standard, the `typeof` keyword is disabled, as it's a GCC extension.
The GCC documentation recommends:

Currently, g_object_ref() and g_object_ref_sink() return a
gpointer which can mask issues when assigning to fields or
returning from a function.
To help catch these type of programming errors, we can propagate
the type of the parameter through the function call on GCC
using the typeof() C language extension.
This will cause offending code to have a warning, but will
continue to be source and binary compatible.
This is only enabled when GLIB_VERSION_MAX_ALLOWED is 2.56 or greater.

It's theoretically possible that we could have a case where this would
actually return NULL, but it's difficult to imagine a valid program that
would contain such a case.
