gutils.[hc] is a bit of a grab bag, so lets start cleaning
things up by moving all the environment-related functions
into separate genviron.[hc] files.
The private _g_getenv_nomalloc has been moved to its sole caller.
When spawning a child process, it is not safe to call setenv() before
the fork() (because setenv() isn't thread-safe), but it's also not
safe to call it after the fork() (because it's not async-signal-safe).
So the only safe way to alter the environment for a child process from
a threaded program is to pass a fully-formed envp array to
exec*/g_spawn*/etc.
So, add g_environ_getenv(), g_environ_setenv(), and
g_environ_unsetenv(), which act like their namesakes, but work on
arbitrary arrays rather than working directly on the environment.

If gtk-doc sees 'Returns ...' written in the text of the documentation
for a macro, it thinks that you are talking about the return value.
Avoid doing that and use 'Returns:' explicitly if we mean to.
Use the opt-out mechanism introduced in gtk-doc 1.16 to work
around problems with the _utf8 renaming games that the win32
port is playing in our headers.

Bug 570501 - g_win32_get_system_data_dirs uses invalid conversion
of function pointer to object pointer
* glib/gutils.c (g_win32_get_system_data_dirs_for_module): Change
the type of the function's parameter to be explicitly a function
pointer.
* glib/gutils.h (_g_win32_get_system_data_dirs): Modify
declaration and the only caller, the inline
_g_win32_get_system_data_dirs(), accordingly. Add comments
pointing out these are internal GLib functions.

Bug 562638 – GDebugKey key member should be const
* glib/gutils.h: Change GDebugKey key member from gchar * to
const gchar *.

2008-09-13 Tor Lillqvist <tml@novell.com>
* glib/gutils.h
* glib/gwin32.h: Deprecate G_WIN32_DLLMAIN_FOR_DLL_NAME(),
g_win32_get_package_installation_directory() and
g_win32_get_package_installation_subdirectory() as their
documentation has warned for a while. Sorry that I forgot to do
this before 2.18.0.
* glib/gwin32.c (g_win32_get_package_installation_directory):
Print a warning if a non-NULL package parameter is passed to this
function, as that is deprecated usage, as the documentation says.

* glib/glib.h: #define __GLIB_H_INSIDE__ around including
everything.
* glib/*.h: check for that define instead of __G_LIB_H__ if
G_DISABLE_SINGLE_INCLUDES is defined.
* glib/gdatasetprivate.h: #include <glib.h> instead of
<glib/gdataset.h>
svn path=/trunk/; revision=6875
* glib/gutils.h: Use "__attribute__ ((__gnu_inline__))" for inlining
if either __GNUC_STDC_INLINE__ or __GNUC_GNU_INLINE__ are defined. In
gcc version prior to 4.3 no correct C99-inline was implemented which
has semantic differences to GNU inline.

* glib/*.h: make it possible to disable single-file includes by
defining G_DISABLE_SINGLE_INCLUDES when building against GLib.
Approved by Tim Janik.
* glib/glib.h: include <glib/gslice.h>.
* glib/gi18n.h
* glib/gi18n-lib.h
* glib/gprintf.h: include <glib.h> so the above works when these
files are included without including <glib.h> first.

* glib/gutils.h: Add a version of G_INLINE_FUNC for
__GNUC__ && __GNUC_STDC_INLINE__, patch by Jakub Jelinek
svn path=/trunk/; revision=6616
2008-02-24 Tor Lillqvist <tml@novell.com>
* glib/gutils.h: Mention G_WIN32_DLLMAIN_FOR_DLL_NAME() will be
deprecated in the future.
* glib/gutils.c: Drop use of G_WIN32_DLLMAIN_FOR_DLL_NAME(). Use a
minimal DllMain() instead that just saves the DLL handle.
(g_win32_get_system_data_dirs_for_module, _glib_get_locale_dir)
(get_module_share_dir): Use
g_win32_get_package_installation_directory_of_module().

* glib/gutils.h: don't define __GNUC_PREREQ which is not in the glib
namespace. for gcc, define G_INLINE_FUNC to "static inline" as with
all other C compilers, because newer GCC versions incompatibly
changed "extern inline" semantics.

Add support for a number of special directories, as
defined by the xdg-user-dirs specification. (#432651,
Bastien Nocera, Emmanuele Bassi, Michael Natterer)
* glib/glib.symbols:
* glib/gutils.[hc]: Add the GUserDirectory enum and
g_get_user_special_dir(), with implementations based
on the xdg-user-dirs spec and on native interfaces
for Win32 and Carbon.
* configure.in: Add Carbon checks.
* tests/tetsglib.c: Test g_get_user_special_dir().

__builtin_clzl for g_bit_storage if available (#371670).
* tests/Makefile.am:
* tests/bit-test.c: New test, to test g_bit_* operations against
naive and builtin implementations.

* glib/gslice.c (slice_config_init): initialize GSlice config from
G_SLICE environemtn variable. we support G_SLICE=always-malloc
currently, which forces all g_slice_*() allocations to use the system
malloc instead.
* glib/gutils.c:
g_parse_debug_string(): added a note about not using g_malloc() here.
_g_getenv_nomalloc(): getenv() variant that doesn't use g_malloc or
g_slice. contains only guesswork in the WIN32 branch.
2005-08-31 Tor Lillqvist <tml@novell.com>
* glib/gutils.h: Wrapping atexit() is a bad idea on Windows, where
the EXE and each DLL have their own atexit function chains.
#define g_atexit as atexit instead. This means it has a
better chance of doing what the caller wants. For instance,
gtkhtml calls g_atexit() registering a function in gtkhtml
itself. This caused a crash when g_atexit() was implemented as a
function in the GLib DLL. The gtkhtml DLL was already unloaded by
the time the GLib DLL got unloaded.
* glib/gutils.c: #undef the #define mentioned above, to also get a
real g_atexit() into the DLL for backward compatibility. Document
the Windows behaviour of g_atexit(), and document the varying ways
atexit() can behave in the context of dynamically loaded modules
on Unix.
2005-07-20 Tor Lillqvist <tml@novell.com>
* glib/gutils.h (g_win32_get_system_data_dirs): Make this an
inline function. Define it only if G_CAN_INLINE and not
C++. (#173098)
2005-06-22 Tor Lillqvist <tml@novell.com>
* glib/gutils.c (g_get_host_name): New function. Returns the
machine's name, or one of its names. Document that it is
best-effort only, and not guaranteed to be unique or anything.
(g_get_any_init): Get the host name here. On Unix use
gethostname(), on Windows use GetComputerName(). (#5200)
* glib/gutils.h
* glib/glib.symbols: Add here, too.
* tests/testglib.c: Test it.
2005-04-19 Tor Lillqvist <tml@novell.com>
* glib/gutils.h: Minor comment improvement.
2005-04-18 Tor Lillqvist <tml@novell.com>
* glib/gfileutils.c: No <sys/wait.h> on Win32. Definition of
save_errno was missing in one place.

Improve g_get_system_data_dirs() on Windows. A library that calls
g_get_system_data_dirs() might be installed in a different
top-level prefix than GLib or the application being run.
* glib/gutils.h (g_win32_get_system_data_dirs): New static
function defined in this header. Calls
g_win32_get_system_data_dirs_for_module() passing the address of
itself as parameter. g_get_system_data_dirs() is #defined as this
function.
* glib/gutils.c (g_win32_get_system_data_dirs_for_module): New
function. If the address parameter is non-NULL, the corresponding
module's installation location is used for one of the returned
path names, in addition to the COMMON_APPDATA, COMMON_DOCUMENTS,
glib top-level and application top-level folders.
(g_get_system_data_dirs): Now just for backward compatibility on
Win32. Just call g_win32_get_system_data_dirs_for_module(NULL).
* glib/glib.symbols: Add g_win32_get_system_data_dirs_for_module.
