Supports %OB (alternative, standalone, nominative) month name along
with the old %B (primary, in a complete date format context, genitive)
month name. Similarly %Ob and %Oh for abbreviated month names.
Depending on the underlying operating system uses nl_langinfo()
or provides our custom implementation.

Since commit 96ebcee8c4, we don’t actually need libmount 2.28. Lower our
dependency to 2.23 so that we can continue to build against CentOS 7.

Building against libmount installed into a non-default prefix wasn’t
working, as we were using #include <libmount/libmount.h> rather than
the correct #include <libmount.h> — all the mount.pc pkg-config files
set `Cflags: -I${includedir}/libmount`.
Fixing this while retaining the fallback support for versions of
libmount without a pkg-config file would have been tricky (we would need
to work out a suitable -I flag to set in LIBMOUNT_CFLAGS) to still be
able to use the correct #include path). Thankfully, libmount gained
pkg-config support a long time ago, so I think we can safely drop the
fallback code. In particular, Debian Jessie, Ubuntu Trusty, and CentOS 5
all ship a mount.pc file.

res_query() uses global state in the form of the struct __res_state
which contains the contents of resolv.conf (and other things). On Linux,
this state seems to be thread-local, so there is no problem. On OS X,
however, it is not, and hence multiple res_query() calls from parallel
threads will compete and return bogus results.
The fix for this is to use res_nquery(), introduced in BIND 8.2, which
takes an explicit state argument. This allows us to manually store the
state thread-locally. If res_nquery() isn’t available, we fall back to
res_query(). It should be available on OS X though. As a data point,
it’s available on Fedora 27.
There’s a slight complication in the fact that OS X requires the state
to be freed using res_ndestroy() rather than res_nclose(). Linux uses
res_nclose().
(See, for example, the NetBSD man page:
https://www.unix.com/man-page/netbsd/3/res_ninit/. The Linux one is
incomplete and not so useful:
http://man7.org/linux/man-pages/man3/resolver.3.html.)
The new code will call res_ninit() once per res_nquery() task. This is
not optimal, but no worse than before — since res_query() was being
called in a worker thread, on Linux, it would implicitly initialise the
thread-local struct __res_state when it was called. We’ve essentially
just made that explicit. In practical terms, this means a
stat("/etc/resolv.conf") call per res_nquery() task.
In future, we could improve this by using an explicit thread pool with
some manually-created worker threads, each of which initialises a struct
__res_state on spawning, and only updates it on receiving
the #GResolver::reload signal.

The chmod of all the scripts we generate from a template via configure
is necessary because configure will not preserve the bits of the
template when generating a new file.
There's no explanation for it, and you have to hunt it down the commit
history. Since Meson does the right thing, we added the executable bit
on the templates, but we cannot remove the AC_CONFIG_COMMANDS macro from
the Autotools build without breaking it. Let's document this, to avoid
nasty surprises.
GLib makes various assumptions about aliasing throughout its codebase,
and compiling with -fstrict-aliasing has been demonstrated to cause
problems (for example, bug #791622). Explicitly disable strict aliasing
as a result.

SystemTap tapsets are architecture-specific, as they include the full
path to the .so file for each probe they reference. Hence, we should
install them in an architecture-specific path, or multiarch systems will
suffer from collisions between them.
A better long-term solution, using $libdir rather than the
non-architecture-specific $datadir, is under discussion upstream:
https://sourceware.org/bugzilla/show_bug.cgi?id=20264; but this will do
for now.

Passing -z nodelete without the shared library flags on Solaris results in
ld: fatal: option '-z nodelete' is incompatible with building a dynamic executable
which causes the configure test to falsely report its not supported.

Specifically controlling the location of this file, rather than simply
using $libdir, allows one to avoid conflicting with the same default
location as the gnulib localcharset module uses.

It is outdated and no longer effectively used. It was originally in
place to prevent rebuilding generated files (from a tarball) if the
right build tools (awk, Perl, indent) were not available. However, we no
longer use indent, we have hard-required awk for a while, and the only
places the @REBUILD@ substitution was still used were for
glib-genmarshal, which has recently been rewritten in Python (so no
longer depends on whether Perl is available).
Drop the whole lot.

We're eventually going to drop Autotools, but in the meantime we should
probably use idiomatic options and reduce warnings.
GLib is pretty much already safe for subdir-objects to be enabled,
except in the GIO tests, where the build references files that are
generated in a different level. For that, we can use the same solution
employed by GTK+, and link the appropriate file in the right
sub-directory.

Instead of requiring --enable-compile-warnings or
--enable-compile-warnings=yes, allow any value which is not ‘no’. This
enables compile warnings for --enable-compile-warnings=maximum or
--enable-compile-warnings=error, which are common values for other GNOME
projects. While we don’t change our behaviour for [yes, maximum, error],
at least it means the warnings are enabled now, rather than disabled.

Python 2.7 is the last stable release of the 2.x series, as per PEP
404: http://legacy.python.org/dev/peps/pep-0404/
Python 2.7 is also 7 years old, and maintained until 2020.
We're in the process or rewriting other tools in Python to reduce the
number of dependencies of GLib.
Additionally, making glib-genmarshal a Python script reduces the
complexity when cross-compiling, as we don't need a native build to
generate the marshallers.
