Solaris/OpenSolaris/OpenIndiana define FIONREAD in sys/filio.h.
This commit adds a configure check for this header, and includes
it conditionally in gio/gsocket.c.
Patch by Fabian Groffen, bug 675524.
Default to generate man pages if the required tools and
stylesheets are found. Error out if --enable-man is given
but tools or stylesheets are missing.
The "-framework" linker flag takes a second word as a parameter. If
they are passed separated with whitespace, some flag-handling routines
may not know to keep the two words together as a single unit. Use
-Wl,, to pass multiple words without embedded whitespace.

Not doing so is an evil trap, sadly. This patch has been
compile-checked on Fedora 16, and I've verified that the generated
config.status and config.h is exactly the same.

This way any prerequisites for e.g. AC_CHECK_HEADER are always executed
before the 'if'.

If action-if-found is not specified, AC_CHECK_LIB will append the library
to LIBS. As we don't want to link everything against libelf, reset LIBS
after doing the checks.
When cross-compiling with gcc >= 4.5 AC_CHECK_ALIGNOF fails to detect the
correct alignment. Without a previous AC_CHECK_TYPE for the same type, the
alignment is silently set to '0'.
This makes sure that configure fails and reports the problem.

These binaries are now only used by the test suite. glib-genmarshal
*used* to be required to generate marshallers, but isn't anymore now
that we use libffi (via g_cclosure_marshal_generic).

This patch solves two problems:
First, it allows builders to optionally cut the circular dependency
between dbus and glib by disabling the modular tests (just like how
the tests can be disabled in dbus).
Second, the tests are entirely pointless to build if cross-compiling.
It also moves us slightly closer to the long term future we want where
the tests are a separate ./configure invocation and run against the
INSTALLED glib, not the one in the source tree. This would allow us to
run the tests constantly, not just when glib is built.

This is needed because glib-mkenums doesn't handle #ifdef values in
enums, and so it needs to have all values always defined in the enum.
When not available, define the missing values to a negative value.
It seems that there is quite a bit of variation out there, in
terms of libelf versions and API. Make the checks more thorough,
by not only checking for elf_begin, but also some of the shdr function
that we need. Also, explicitly check for libelf.h.
This should address bug 673132 and 673253.
On some systems gelf.h may not be stored under the top level include
directory in which case we need to add the correct include paths in
cflags by using pkg-config(1).
When inserting custom code to AC_CHECK_ALIGNOF, make sure to not replace
the default includes, but instead append to them.
This fixes ALIGNOF_GUINT32 and ALIGNOF_GUINT64 that were both 0 when cross
compiling. The third 'unsigned long' test wasn't affected because the
AC_CHECK_ALIGNOF call didn't specify the optional 2nd parameter.
We need a stable sort, and we might as well always use it rather
than have multiple sort versions. This picks up the glibc
merge sort implementation which it uses by default for qsort,
except we don't fall back to non-stable quicksort in some cases
like glibc

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

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.
