How distressing.  Would you please say more?  That sounds like it coule
be a serious bug, in which case I'd rather we go after that than try to
work around this just for the Solaris native assembler.  On the other
hand, perhaps GNU as is smart enough to create relocations in this case,
in which case something like your patch might be best -- though it still
sounds like we might need a more general
AS_ALLOWS_SUBTRACTION_OF_LABELS_IN_DIFFERENT_SECTIONS macro, or some such.
