GCC does not yet support ISO C11 atomic operations, but it has
compatible versions available as an extension. Use these for load and
store if they are available in order to avoid emitting a hard fence
instruction (since in many cases, we do not need it -- on x86, for
example).
For now we use the fully seqentially-consistent memory model, since
these APIs are documented rather explicitly: "This call acts as a full
compiler and hardware memory barrier".
In the future we can consider introducing new APIs for the more relaxed
memory models, if they are available (or fall back to stricter ones
otherwise).

g_type_is_fundamentally_a (see bug 730984) is a new API/ABI and is
marked with a version macro. We should therefore avoid its
unconditional use from G_IS_OBJECT() and G_IS_PARAM_SPEC() which are
APIs that have been around for a long time.
This prevents deprecation warnings from being emitted when these
functions are used with an older GLIB_VERSION_MAX_ALLOWED and also
prevents linking to the new ABI in that case (so that it's possible to
use the resulting binary with an older version of GLib).

Add a flag to prevent the automatic emission of the "notify" signal
during g_object_set_property().
If this flag is set then the class must explicitly emit the notify
for themselves. This is already standard practice on most classes, but
we cannot simply remove the existing behaviour because there are surely
many cases where it is needed.

Like the Visual Studio 2012 project files, the Visual Studio 2013 files are
largely the same as the Visual Studio 2010 project files, so support
Visual Studio 2013 by updating the autotools scripts that is used for
Visual Studio 2012. This means that project files for Visual Studio 2012
and Visual Studio 2013 can be maintained by simply maintaining the Visual
Studio 2010 project files, adding minimal maintenance overhead.
It turns out that due to a recent gdm change, the inherited
signal mask has SIGUSR1 blocked - which is bad news for
tests using SIGUSR1. Fix the test by explicitly checking the
signal mask before using SIGUSR1.
GResolver doesn't do full validation of its inputs, so in some of
these tests, the fact that we were getting back
G_RESOLVER_ERROR_NOT_FOUND is because the junk string was getting
passed to an upstream DNS resolver, which returned NXDOMAIN. But if
there's no network on the machine then we'd get
G_RESOLVER_ERROR_INTERNAL instead in that case.
This is done so that _WIN32_WINNT may be overridden in the project files,
if needed, so that one can access the Vista+ (or so) Windows APIs easier
by using "preprocessor defines" (or so) in the Visual C++ project files.
The mapping-test is failing under gnome-continuous. I suspect this
is simply due to running many tests in parallel, and mapping-test
being racy. Replace the blind sleep by signals, to avoid the
races.
Make use of if_indextoname() and if_nametoindex() when building against
Window Vista/Server 2008 or later, as these are provided by the system.
This is not turned on by default as we still want to support XP and
Server 2003-turn this on by changing _WIN32_WINNT to 0x600 or later prior
to compiling GLib.
