	* config/darwin-c.c (darwin_cpp_builtins): Define a '__weak'
	macro if Objective-C GC is being used.
	* config/darwin.c (darwin_handle_objc_gc_attribute): Correctly
	propagate GC attribute to ..._TYPE nodes, even for functions
	and arrays.
	* config/darwin.h (SUBTARGET_ATTRIBUTE_TABLE): Restrict use of
	GC attribute to ..._TYPE nodes.
	* doc/invoke.texi: Document '-fobjc-gc' switch.
