* 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!!!
