This is a partial change of the previous work[0].
On 64 bit Android since android-23, 'handle = dlopen(NULL); dlsym(handle)'
doesn't work. Instead, only 'dlsym(RTLD_DEFAULT)' returns a valid pointer.
However, RTLD_DEFAULT is defined as '(void *) 0x0' on 64bit Android which
is usually used for invalid value so this patch allows the specific case.

For versions of GCC which support it (≥ 4), define G_MODULE_EXPORT as
__attribute__((visibility("default"))). This is normally a no-op, unless
compiling with -fvisibility=hidden, in which case it marks a symbol to
be publicly exported from the library, which is what G_MODULE_EXPORT is
for. Previously G_MODULE_EXPORT has only worked on Windows.
The compatibility check for whether the compiler supports
__attribute__((visibility)) is based on the __GNUC__ define, and is
similar to the check done in configure.ac for defining G_GNUC_INTERNAL.

If we have an input parameter (or return value) we need to use (nullable).
However, if it is an (inout) or (out) parameter, (optional) is sufficient.
It looks like (nullable) could be used for everything according to the
Annotation documentation, but (optional) is more specific.
Since we are no longer using sgml mode, using /* */ to
escape block comments inside examples does not work anymore.
Switch to using line comments with //
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.

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.

Back in the far-off twentieth century, it was normal on unix
workstations for U+0060 GRAVE ACCENT to be drawn as "‛" and for U+0027
APOSTROPHE to be drawn as "’". This led to the convention of using
them as poor-man's ‛smart quotes’ in ASCII-only text.
However, "'" is now universally drawn as a vertical line, and "`" at a
45-degree angle, making them an `odd couple' when used together.
Unfortunately, there are lots of very old strings in glib, and also
lots of new strings in which people have kept up the old tradition,
perhaps entirely unaware that it used to not look stupid.
Fix this by just using 'dumb quotes' everywhere.

All locks are now zero-initialised, so we can drop the G_*_INIT macros
for them.
Adjust various users around GLib accordingly and change the docs.

* gmodule.symbols: New file.
* gmodule.c: Bypass the Windows ABI compatibility symbols on
64-bit Windows. Thus no need to keep the file name in system
codepage around on 64-bit Windows either.
* Makefile.am: Produce gmodule.def from gmodule.symbols. Dist
gmodule.symbols instead of gmodule.def.
* gmodule.def: Drop from SVN.
svn path=/trunk/; revision=7259
2008-05-05 Michael Natterer <mitch@imendio.com>
* Makefile.am. build with G_DISABLE_SINGLE_INCLUDES to prevent
code from being checked in that breaks the build of applications
which use G_DISABLE_SINGLE_INCLUDES.
* gmodule.c: #include "glib.h" instead of "glibconfig.h"

* gmodule.c (g_module_open): Include the module file

fails. (#448484, Gustavo Carneiro)

* gmodule.c: applied patch from Christian Persch to support
G_DEBUG flags resident-modules and bind-now-modules, bug #345099.
2004-12-31 Tor Lillqvist <tml@iki.fi>
* gmodule.c (g_module_open): It's wrong to call g_file_test() with
more than one test (both G_FILE_TEST_EXISTS and _IS_REGULAR). (It
would succeed even if the pathname existed as a nonregular file.)
Just G_FILE_TEST_IS_REGULAR works fine. (#162594)
2004-11-04 Tor Lillqvist <tml@iki.fi>
* gmodule-win32.c (_g_module_open): Argument is in UTF-8. Use wide
character Win32 API if present.
* gmodule.c (parse_libtool_archive, g_module_open): Convert file
name to UTF-8 before storing in the error message string.
* gmodule.c (parse_libtool_archive): Use g_open().

* configure.in: Set the gmodule suffix to 'a' for aix and
use the aix gmodule implementation. (#85930, Laurent Vivier)
Bug #85930, Laurent Vivier:
* gmodule-ar.c: Implementation of native module management for AIX.
* gmoduleconf.h.in:
* gmodule.c: Support gmodule-ar.c
Fri Feb 20 02:39:03 2004 Tim Janik <timj@gtk.org>
* applied patch from David Schleef <ds@schleef.org> which implements
a G_MODULE_BIND_LOCAL flag to g_module_open() to disable global
symbol registration.

* gmodule.c (g_module_open): Fix typo when checking
if file + module_suffix exists. (Miroslaw Dobrzanski-Neumann,
