* macosx/tkMacOSXNotify.c: sync with tclUnixNotfy.c changes since

	2004-06-22, added compile time check for threaded tcl core, removed
	unthreaded code paths as they are never used anyway, fixed
	TkMacOSXAlertNotifier() implementation.

	* unix/Makefile.in: added TCL_STUB_LIB_FILE, needed for unexporting of
	symbols from libtclstub to avoid duplicate symbol warnings.

	* unix/tcl.m4 (Darwin): added configure checks for recently added linker
	flags -single_module and -search_paths_first to allow building with
	older tools (and on Mac OS X 10.1), use -single_module in SHLIB_LD and
	not just T{CL,K}_SHLIB_LD_EXTRAS, added unexporting from Tk of symbols
	from libtclstub to avoid duplicate symbol warnings, added PLAT_SRCS
	definition for Mac OS X, defined MODULE_SCOPE to __private_extern__.
	(SC_MISSING_POSIX_HEADERS): added caching of dirent.h check.

	* unix/configure: autoconf-2.59
