There are cases when it should be possible to define at compile time
what range of functions and types should be used, in order to get,
or restrict, the compiler warnings for deprecated or newly added
types or functions.
For instance, if GLib introduces a deprecation warning on a type in
version 2.32, application code can decide to specify the minimum and
maximum boundary of the used API to be 2.30; when compiling against
a new version of GLib, this would produce the following results:
- all deprecations introduced prior to 2.32 would emit compiler
warnings when used by the application code;
- all deprecations introduced in 2.32 would not emit compiler
warnings when used by the application code;
- all new symbols introduced in 2.32 would emit a compiler warning.
Using this scheme it should be possible to have fairly complex
situations, like the following one:
assuming that an application is compiled with:
GLIB_VERSION_MIN_REQUIRED = GLIB_VERSION_2_30
GLIB_VERSION_MAX_ALLOWED = GLIB_VERSION_2_32
and a GLib header containing:
void function_A (void) GLIB_DEPRECATED_IN_2_26;
void function_B (void) GLIB_DEPRECATED_IN_2_28;
void function_C (void) GLIB_DEPRECATED_IN_2_30;
void function_D (void) GLIB_AVAILABLE_IN_2_32;
void function_E (void) GLIB_AVAILABLE_IN_2_34;
any application code using the above functions will get the following
compiler warnings:
function_A: deprecated symbol warning
function_B: deprecated symbol warning
function_C: no warning
function_D: no warning
function_E: undefined symbol warning
This means that it should be possible to gradually port code towards
non-deprecated API gradually, on a per-release basis.

This lets you poke at resources in elf files and
standalone resource bundles. So far, only listing
and extracting resources is supported. The support
for elf files requires libelf.
In non-UTF-8 locales, the translations and nl_langinfo() return values
must be converted to UTF-8 before being returned to the caller.
Likewise, when making a recursive call to expand a format like '%x',
the format string must first be converted to UTF-8.

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:

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.
