Add a G_GNUC_INTERNAL macro to mark function declarations as internal and

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().
