When the function in the test program is inlined, all bets are
off whether the detection will work correctly or not. Make it
harder for the compiler to play games on us by making the
function recursive.

In Windows development environments that have it, <unistd.h> is mostly
just a wrapper around several other native headers (in particular,
<io.h>, which contains read(), close(), etc, and <process.h>, which
contains getpid()). But given that some Windows dev environments don't
have <unistd.h>, everything that uses those functions on Windows
already needed to include the correct Windows header as well, and so
there is never any point to including <unistd.h> on Windows.
Also, remove some <unistd.h> includes (and a few others) that were
unnecessary even on unix.

Assume unix platforms support the original POSIX.1 standard.
Specifically, assume that if G_OS_UNIX, then we have chown(),
getcwd(), getgrgid(), getpwuid(), link(), <grp.h>, <pwd.h>,
<sys/types.h>, <sys/uio.h>, <sys/wait.h>, and <unistd.h>.
Additionally, since all versions of Windows that we care about also
have <sys/types.h>, we can remove HAVE_SYS_TYPES_H checks everywhere.
Also remove one include of <sys/times.h>, and the corresponding
configure check, since the include is not currently needed (and may
always have just been a typo for <sys/time.h>).

Assume all supported platforms implement C90, and therefore they
(correctly) implement atexit(), memmove(), setlocale(), strerror(),
and vprintf(), and have <float.h> and <limits.h>.
(Also remove the configure check testing that "do ... while (0)" works
correctly; the non-do/while-based version of G_STMT_START and
G_STMT_END was removed years ago, but the check remained. Also, remove
some checks that configure.ac claimed were needed for libcharset, but
aren't actually used.)
Note that removing the g_memmove() function is not an ABI break even
on systems where g_memmove() was previously not a macro, because it
was never marked GLIB_AVAILABLE_IN_ALL or listed in glib.symbols, so
it would have been glib-internal since 2004.

Remove workarounds for NeXTStep (last released in 1995), SunOS (1994),
HP-UX 9.x (1992) and 10.x (1995), OSF/1 / Digital UNIX / Tru64 UNIX
4.x (1999), and AIX 4.x (1999).
HP-UX 11 implements dlopen(), so dropping support for earlier versions
also lets us remove the HP-UX-specific gmodule-dld.

Since the initial addition of BeOS support in 1999, there has only
been one update to it (in 2005, and it wasn't even very big). GLib is
known to not currently build on Haiku (or presumably actual BeOS)
without additional patching, and the fact that there isn't a single
G_OS_BEOS check in gio/ is suspicious.
Additionally, other than the GModule implementation, all of the
existing G_OS_BEOS checks are either (a) "G_OS_UNIX || G_OS_BEOS", or
(b) random minor POSIXy tweaks (include this header file rather than
that one, etc), suggesting that if we were going to support Haiku, it
would probably be simpler to treat it as a special kind of G_OS_UNIX
(as we do with Mac OS X) rather than as its own completely different
thing.
So, kill G_OS_BEOS.

AC_TRY_LINK should be used instead of AC_TRY_COMPILE because the code
will compile everywhere, either producing ``atomic'' code, or an
external reference to __sync_bool_compare_and_swap.

This was introduced for Solaris performance theoretically;
we have never been able to use it on Linux/glibc because
the UTF-16 BOM state isn't reset.
We have no data about Solaris performance; were some to
still exist, we could reintroduce the code with an explicit
check for Solaris, not a check for glibc.

...instead of detecting glibc and using _GNU_SOURCE manually. This
should fix the build when using glibc-emulating libraries; we can
defer portability work to autoconf.

Otherwise we have to rely on pthread_cond_timedwait() actually using
the monotonic clock, which might be true or not. On Android at least
it is using the realtime clock, no pthread_condattr_setclock() is available
but instead pthread_cond_timedwait_monotonic() can be used.
OS X's getaddrinfo() only supports IPv6 scope IDs that are interface
names, not numbers. So use if_indextoname() to get the name of an
interface and construct an address using that.

Extents-based filesystems like knowing in advance how much data will be
written to a file in order to prevent fragmentation. If we have it, use
posix_fallocate() before writing data in g_file_set_contents().

Perform a substantial cleanup of the build system with respect to
building and installing testcases.
First, Makefile.decl has been renamed glib.mk and substantially
expanded. We intend to add more stuff here in the future, like canned
rules for mkenums, marshallers, resources, etc.
By default, tests are no longer compiled as part of 'make'. They will
be built when 'make check' is run. The old behaviour can be obtained
with --enable-always-build-tests.
--disable-modular-tests is gone (because tests are no longer built by
default). There is no longer any way to cause 'make check' to be a
no-op, but that's not very useful anyway.
A new glibtests.m4 file is introduced. Along with glib.mk, this
provides for consistent handling of --enable-installed-tests and
--enable-always-build-tests (mentioned above).
Port our various test-installing Makefiles to the new framework.
This patch substantially improves the situation in the toplevel tests/
directory. Things are now somewhat under control there. There were
some tests being built that weren't even being run and we run those now.
The long-running GObject performance tests in this directory have been
removed from 'make check' because they take too long.
As an experiment, 'make check' now runs the testcases on win32 builds,
by default. We can't run them under gtester (since it uses a pipe to
communicate with the subprocess) so just toss them in TESTS. Most of
them are passing on win32.
Things are not quite done here, but this patch is already a substantial
improvement. More to come.
See https://live.gnome.org/GnomeGoals/InstalledTests for more
information.
The tests now support being run both uninstalled and installed, so
'make check' works for those who want it. For tests which need data
files, the way this works is they look in the compiled in value of
SRCDIR by default, and the generated tests use "env G_TEST_DATA=" to
override that.
This patch only converts glib/tests for now; if this patch looks good,
I'll do the rest of the tests.

This ancient code was attempting to cope with (unknown) systems whose
malloc() prototype was incompatible with the standard. This test was
fragile; it would break if the build environment provided -Wall in
CFLAGS.
Now that it's 2013, let's assume that target systems have a sane
malloc(). If someone complains, we can revisit this.

Some (broken) toolchains for example trip up
-Werror=missing-prototypes in system headers. This patch allows
people to skip the formerly hardcoded "baseline" warnings.
