	  * builtins.c (expand_builtin_setjmp): Mark next_lab as used.

     buf_addr = expand_expr (TREE_VALUE (arglist), NULL_RTX, VOIDmode, 0);

     next_lab = gen_label_rtx ();
  +  LABEL_PRESERVE_P (next_lab) = 1;
     cont_lab = gen_label_rtx ();

     expand_builtin_setjmp_setup (buf_addr, next_lab);

Even with this workaround patch I still get a crash using a cross
compiler, so I guess I'll have to wait for Jeff's reworking of Bernd's
patch.

Thanks,
