It is not always needed to generate and install gmo files, for example
when building for Android or Windows that often doesn't have libintl to
use them anyway.
At least all GStreamer modules have this same option.
This is enough for most Debian buildds, including embedded devices
like mips and powerpcspe. It is not enough for hppa (PA-RISC), but that
architecture is so uniquely slow that it might make more sense to
special-case it downstream.

armv5 Linux systems implement __sync_bool_compare_and_swap() and
friends by calling a function provided by the kernel. This is not
technically an atomic intrinsic, so gcc doesn't define
__GCC_HAVE_SYNC_COMPARE_AND_SWAP_4 in this case, but it's good
enough for us. Extend the current Android special case to cover
GNU/Linux too.
The possibilities are:
* __sync_foo detected and __GCC_HAVE_SYNC_COMPARE_AND_SWAP_4 predefined:
calls to __atomic_foo or __sync_foo primitives are inlined into user
code by gatomic.h
* __sync_foo detected but __GCC_HAVE_SYNC_COMPARE_AND_SWAP_4 not
predefined: user code has an extern reference to g_atomic_foo(),
which calls __atomic_foo or __sync_foo because we defined
__GCC_HAVE_SYNC_COMPARE_AND_SWAP_4 when compiling GLib itself
* Windows: user code has an extern reference to g_atomic_foo(),
which calls InterlockedFoo()
* !defined(G_ATOMIC_LOCK_FREE): user code has an extern reference to
g_atomic_foo(), which emulates atomic operations with a mutex

Closes: #1576
FreeBSD 12 adds a new header, sys/auxv.h, to declare a function, elf_aux_info,
for public use, which was considered an internal function in previous releases.
This new function provides similar functionality with glibc getauxval, which is
also declared in the same header, but their interfaces are not compatible. Since
the only usage of sys/auxv.h is in g_check_setuid and FreeBSD already has
issetugid to provide the required functionality, we fixes the compilation error
by adding a check for getauxval function to prevent g_check_setuid from calling
getauxval when sys/auxv.h is found but getauxval is not available.

Partial revert of commit a7a6449f4d.
Checking for the availability of m4 for installing m4 macro files
creates an implicit dependency on m4 even if GLib does not need it; this
prevents building GLib and then installing Autotools in order to build a
project that depends on GLib.
Closes#1520
We already set -Wformat=2, which implies -Wformat-security, so there’s
no need to test for and set -Wformat-security separately.
The test for -Wformat-security never worked anyway, since gcc complains
if it’s specified without also setting -Wformat to some value. The
complaint causes configure.ac/meson.build to assume the option doesn’t
work.

I can’t see this being used anywhere in GLib, or in my /usr/include
directory. I’m also not sure how configure.ac ends up defining it — it’s
certainly as a side-effect of something, and not deliberate.

Previously we weren’t checking for it in meson.build (but were checking
for it in configure.ac, courtesy of glib-gettext.m4). Roughly emulate
the checks from glib-gettext.m4, checking for bind_textdomain_codeset()
in whichever libintl implementation we found ngettext() in.
meson.build still doesn’t implement the full set and order of checks in
glib-gettext.m4; there’s still a FIXME about that in meson.build.

Previously it was hard-coded to true, rather than being based on the
calculations actually made by meson.build.

This is equivalent to the AC_FUNC_PRINTF_UNIX98 macro which we use in
configure.ac. There may still be some obscure Unix platforms which don’t
natively support positional parameters, 20 years on.

This is what Autotools does, and it's what all consumers of the
GModule API expect. Without this change, people on macOS upgrading to
a GLib built with Meson will find that their plugins no longer load.
Projects that use Meson and the `g_module_build_path()` API such as
glib-networking should pass `name_suffix:` to `shared_module()` to
ensure that plugins continue to be called libfoo.so on macOS.
New GModule API will eventually be added to address this.

The goal of this commit is to reduce differences between the autotools and meson build.
With autotools AC_FUNC_ALLOCA was used which defines HAVE_ALLOCA_H, HAVE_ALLOCA,
C_ALLOCA. meson tried to replicate that with has_function() but alloca can be a macro
and and is named _alloca under Windows. Since we require a working alloca anyway
and only need to know if the header exists replace AC_FUNC_ALLOCA with a simple
AC_CHECK_HEADERS.
There is still one user of HAVE_ALLOCA in the embedded gnulib, but since alloca is
always provided through galloca.h just force define HAVE_ALLOCA there and add a comment.
The docs were mentioning alloca as an example for cross compiling. Since that variable no
longer exists now replace it with another one.
Check for compile warnings when assigning an int64_t* to a long*,
make gint64 a long long if they occur and assigning an int64_t* to
a long long* doesn't.
Modified by Philip Withnall <withnall@endlessm.com> to support Meson as
well as autotools.

The autotools build set it by default and we use off_t in various places,
even on Windows. Also set it with the meson build to avoid any regressions.
Ideally we shouldn't use off_t and use 64bit capable API on Windows instead, so
we get large file support with MSVC as well.

for a discussion on if/when we can start relying on Python 3 only.
Use Python 3.4 as a new requirement because that's the version used in
SLES 12 and Debian 8 and there is no good reason to require something newer
right now.
The new python module, added with 0.46, works with Python 2 and 3 and
allows to pass a path for the interpreter to use, if the need arises.
Previously the meson build set PYTHON, used in the shebang line of
the scripts installed by glib, to the full path of the interpreter.
The new meson module doesn't expose that atm, but we should set it to
a executable name anyway, and not a full path.
