The m4 and bash completion items are usable and relevant
depending on the host system's configuration. So, we check for the
presence of the programs that these items depend on, and only install
them when those programs are found.
For the Valgrind suppression files, we don't install them on Windows as
Valgrind is currently not supported on Windows.
Als fix the path where the GDB helpers are installed, as the path is
incorrectly constructed.
This will fix the "install" stage when building on Visual Studio at
least as there are some post-install steps that are related to them,
which will make use of these programs.

We want to set _WIN32_WINNT so that functions will be properly found in
the headers, to target the NT6.1+ (Windows 7+) APIs.
Also improve the checks for if_nametoindex() and if_indextoname() on
Windows as they are supported in Windows Vista+, but they have
to be checked by linking against iphlpapi.lib (or -liphlpapi). On other
platforms, they are still checked as they were before.

Instead of hardcoding -DPCRE_STATIC into the CFLAGS of GLib, do the
following on Windows only (since PCRE_STATIC only matters on Windows):
-If there is no installed PCRE, use the included PCRE copy and
enable -DPCRE_STATIC, as we did before.
-If there is a installed PCRE, check whether the PCRE build is a static
or DLL build by checking the linkage against pcre_free() with
PCRE_STATIC defined works. If it does, enable -DPCRE_STATIC.
-On non-Windows builds, do not enable -DPCRE_STATIC

The HAVE_GOOD_PRINTF config variable determines whether we are able to
use the CRT-supplied *printf() functions directly, by determining whether
the CRT-supplied vsnprintf() and snprintf() functions support C99 well
enough.
This means, we need to build the gnulib subdir as a static lib in GLib, and use
the gnulib *printf() functions when:
-We are on Windows
-The CRT's vsnprintf() and snprintf() is not sufficiently C99-compliant.
This will fix the problem when the *printf() functions cause a CRT
abort() call on pre-2015 Visual Studio builds at least, and ensures that
the Visual Studio 2015+ builds will pass the printf tests in GLib, since
the *printf() in Visual Studio 2015/2017's CRT does not support the %n
format specifier, nor the positional parameters (which requires
different _*printf_p*() functions), as indicated by
glib/tests/test-printf.c.

Copy the msvc_recommended_pragmas.h helper header when we build for
Windows, so that people developing/using GLib on Windows can make use
of them in Visual Studio, so that unwanted compiler noise can be
filtered out and code with potentially-problematic warnings can be
attended to.

Some of the dependencies' build systems for Visual Studio do not provide a
pkg-config file upon build, so we use find_library() for them when the
corresponding pkg-config files are not found during Visual Studio builds,
so that one will not need to make up pkg-config files for them, which
could be error-prone. These .lib names match the names that are built
with the officially supported build system that is used by their
respective Visual Studio support.
For ZLib, this will make gio-2.0.pc reflect on the zlib .lib based on
what is found, or whether we use the fallback/bundled ZLib, when we
don't have a pkg-config file for ZLib on MSVC. We still need to depend
on Meson to be updated to put the correct link argument for linking ZLib
in the pkg-config case.

Without this, GNU-specific symbols won't be defined and the compiler
check will pass because GCC will assume that you know what you're
doing since it doesn't know what the symbol prototype is and compiler
checks aren't built with -Wall -Werror.
This will then cause a build failure because the wrong prototype will
be used.
We use it pretty much everywhere in order to get feature detection, and
that's also what the AC_USE_SYSTEM_EXTENSIONS m4 macro defines in the
Autotools build.
https://bugzilla.gnome.org/show_bug.cgi?id=785955
The Meson build has fallen a bit behind the Autotools one, when it comes
to the internally built tools like glib-mkenums and glib-genmarshals.
We don't need to generate gmarshal.strings any more, and since the
glib-genmarshal tool is now written in Python it can also be used when
cross-compiling, and without indirection, just like we use glib-mkenums.
We can also coalesce various rules into a simple array iteration, with
minimal changes to glib-mkenums, thus making the build a bit more
resilient and without unnecessary duplication.
On Visual Studio, the compilation of the check program for va_copy() and
__va_copy() succeeds even though they may not be really available. So,
make sure we include msvc_recommended_pragmas.h which helps us to detect
this situation by bailing out when warning C4013 (which means this
function is really not available) is encountered.
Also make sure that on Visual Studio builds we always include
msvc_recommended_pragmas.h is included so that it helps us to find out
problems in the build, and update comments for dirent.h and sys/time.h
as they are not shipped with any Visual Studio.

This reduces the build-time dependencies of glib to only Python 3,
Meson, and git. Git is also optional if you provide a tarball in
which the subproject directories already exist.
The Python port was done by Jussi Pakkanen on bugzilla:
https://bugzilla.gnome.org/show_bug.cgi?id=779332
This version contains some fixes from that and also changes all
instances of `@` to `\u0040` because Meson does not yet provide a
configure_file() mode that ignores unknown @MACRO@ values.
This is a stub-only library that can be used while building against
MSVC and contains no i18n machinery at all.
The dependencies added indirectly use the libintl.h header, and when
built as a subproject, the header won't be in a path known the
pre-processor.
When no 'name:' kwarg is specified for cc.run, no output is printed.
This makes it difficult to figure out what is causing a pause in the
configure process.
By default, only build man pages and gtk-doc if the build-deps were
found. To force-enable, pass -Dwith-docs=yes and -Dwith-man=yes.
Also use a foreach loop for man pages instead of listing them all
manually
Don't use it project-wide for building everything. Otherwise
symbols for shared modules won't be exposed, e.g. in the
resourceplugin used by the gio resource unit test.
Disable gio tests on Windows, fix .gitignore to not ignore
config.h.meson, and add more things to it.
Rename the library file naming and versioning to match what Autotools
outputs, e.g., libglib-2.0.so.0.5000.2 on Linux, libglib-2.0-0.dll and
glib-2.0-0.dll on Windows with MSVC.
Several more tiny fixes, more executables built and installed, install
pkg-config and m4 files, fix building of gobject tests.
Changes to gdbus-codegen to support out-of-tree builds without
environment variables set (which you can't in Meson). We now add the
build directory to the Python module search path.
