Add a G_GNUC_INTERNAL macro to mark function declarations as internal and

Browse Source 
2004-08-02  Matthias Clasen  <mclasen@redhat.com>

	* glib/gmacros.h: Add a G_GNUC_INTERNAL macro to mark function
	declarations as internal and avoid PLT indirections for
	them.  (#145465, Arjan van de Ven)

	* glib/gunicodeprivate.h:
	* glib/gthreadinit.h:
	* glib/gmessages.h:
	* glib/gdebug.h:
	* glib/gconvert.c: Use G_GNUC_INTERNAL for _g_charset_get_aliases(),
	_g_debug_init(), _g_log_fallback_handler(), _g_mem_thread_init(),
	_g_messages_thread_init(), _g_convert_thread_init(),
	_g_rand_thread_init(), _g_main_thread_init(), _g_atomic_thread_init(),
	_g_mem_thread_private_init(), _g_messages_thread_private_init(),
	_g_utf8_normalize_wc() and _g_unichar_combining_class().

	* glib/gatomic.c: Include gthreadinit.h here to see the declaration
	for _g_atomic_thread_init().

Expands to the GNU C <literal>visibility(hidden)</literal> attribute if the
compiler is <command>gcc</command>. This attribute can be used for marking
library functions as being used internally to the lib only, to not create
inefficient PLT entries. Note that static functions do not need to be marked
as internal in this way. See the GNU C documentation for details.
