	* stdio/stdio.h (__validfp): Use ({...}) rather than a comma
 	expression, to avoid gcc's "value computed is not used" warning.

	* libc-symbols.h (_elf_set_element): Give the set-element variable
 	an `unused' attribute.

	* hurd/hurd/threadvar.h (__hurd_threadvar_location): Declare with
 	__attribute__ ((__const__)).
	* hurd/hurd/signal.h (_hurd_self_sigstate): Likewise.

	* hurd/hurd/userlink.h (_hurd_userlink_link): Properly set
 	LINK->resource.next->resource.prevp when appropriate, not
 	LINK->resource.next->thread.prevp!!!
