	* varasm.c (default_binds_local_p_1): Weakrefs don't bind locally.
	A hidden weak object does bind locally.  Strong linkonce data
	counts like any other strong symbol for binding.
	(weak_finish_1): Don't specially handle weakrefs, they no longer
	arrive here.
	(assemble_alias): Weakrefs can't be TREE_PUBLIC yet.
	* c-common.c (handle_alias_attribute): Allow static aliases
	of variables.
	(handle_weakref_attribute): Don't call declare_weak on weakrefs.
	* gthr-dce.h: Make weakrefs static.
	* gthr-tpf.h: Likewise.
	* gthr-solaris.h: Likewise.
	* gthr-posix.h: Likewise.
	* gthr-posix95.h: Likewise.
	* config/darwin.c (darwin_encode_section_info): static weakref
	variables are not necessarily defined in this translation unit.
	* doc/extend.texi (Function Attributes): Mention that an alias
	attribute creates a definition for the thing it's attached to.
	Change the documentation for weakref to say that the thing
	it's attached to must be static.
