* gthr-dce.h: Do not gthrw-ify pthread_once_init,
pthread_key_delete. From John David Anglin. gthrw-ify
pthread_getunique_np only if it it's not a macro. Delete
UNUSED macro.
(__gthread_objc_condition_allocate, __gthread_objc_condition_deallocate,
__gthread_objc_condition_wait, __gthread_objc_condition_broadcast,
__gthread_objc_condition_signal, __gthread_key_delete): Add
"__attribute__ ((__unused__))" to unused arguments.
(__gthread_recursive_mutex_init_function): Add missing return.
* gthr-dce.h, gthr-tpf.h, gthr-solaris.h, gthr-posix.h,
gthr-posix95.h: Use macro-based approach for name redirection
on targets missing weakref.

* 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.

* gthr-dce.h, gthr-posix.h, gthr-posix95.h, gthr-solaris.h,
gthr-tpf.h: Define __gthrw. For all identifiers that might
be weak, introduce weakrefs or non-weak aliases with __gthrw,
and prefix all uses with __ghtrw.
