This should help getting static builds working on mingw.
Based on a patch by Volker Grabsch, bug 619126.
At the same time, drop the unnecessary GLIB_RT_LIBS variable;
we are already adding -lrt to G_THREAD_LIBS.
If we don't do the cast to the proper size in 32 bits, things like below
doesn't work:
uint8_t u = 20;
void *p;
p = GUINT_TO_POINTER(u);

Add GNetworkMonitor and its associated extension point, provide a base
implementation that always claims the network is available, and a
netlink-based implementation built on top of that that actually tracks
the network state.

For some reason, the setting of g_atomic_lock_free wasn't making it down
to the lower part of the configure script where glibconfig.h was being
generated when building using mingw32-configure.
If we prefix glib_cv_ to the start of the variable name (like everyone
else is doing) then it magically starts working.
I love you, automake.
We clean up the detection of if we should do 'real' atomic operations or
mutex-emulated ones with the introduction of a new (public) macro:
G_ATOMIC_LOCK_FREE. If defined, our atomic operations are guaranteed to
be done in hardware.
We need to use __GCC_HAVE_SYNC_COMPARE_AND_SWAP_4 to determine if our
compiler supports GCC-style atomic operations from the gatomic.h header
because we might be building a program against GLib using a different
set of compiler options (or a different compiler) than was used to build
GLib itself.
Unfortunately, this macro is not available on clang, so it has currently
regressed to using the mutex emulation. A bug about that has been
opened here:
http://llvm.org/bugs/show_bug.cgi?id=11174
These were meant to provide the ability to use GLib directly out of its
build tree but have a couple of rather serious limitations that prevent
their serious use:
- these files only worked with programs built using libtool
- for non-trivial uses, other environment variables will need to be
setup to allow GLib to function properly
- the system doesn't stack well when attempting to use multiple
libraries all uninstalled
The jhbuild --prefix= style system works much better in every way, so we
remove this old hack.
We can just assume that strerror/strsignal are available
nowadays. At the same time, drop use of thread-private storage.
Instead, always return interned strings.

Now that GMutex is exposed we can avoid the dance we did in ./configure
to allocate the correct amount of space for it within the GStaticMutex.
Remove the checks and move the definitions to gthread.h, trying very
hard to keep ABI-stable (even though we will be deprecating this soon).
Implement g_ascii_strto{d,ll,ull} and g_ascii_formatd using
xlocale functions where available. This is slightly faster
and a lot less icky than our homegrown code.

configure.ac defined G_THREAD_SOURCE and gthread-impl would #include it.
Instead, since we only have two thread implementations now, and since we
always use the Windows one only on Windows, move the logic to the
Makefile, predicated on 'if OS_WIN32'. Then have the chosen backend do
the #include "gthread-impl.c" from there.
Remove the G_THREAD_SOURCE define from configure.ac.
In particular, remove the libasyncns import, which was only used by
GUnixResolver, which is only used when threads are not available.
Likewise remove GWin32Resolver, and the hacky broken non-threaded
parts of GIOScheduler.

G_THREADS_ENABLED still exists, but is always defined. It is still
possible to use libglib without threads, but gobject (and everything
above it) is now guaranteed to be using threads (as, in fact, it was
before, since it was accidentally impossible to compile with
--disable-threads).
