  perhaps precisely because without the patch you applied, it was wrong to
  use the __GMPZ_ and _GMP_ variants ? The only difference between __GMPZZ_
  and __GMPZ_ is the definition of compound operator with PODs as
  right-hand types (if you follow the macro maze).

  I _think_ that with the provided patch, it is safe to do s/ZZ/Z/ here. Or
  there's some hidden can of worms somewhere that I haven't seen. Can you
  use your cvs tree to track back these lines to their author ?
As far as I can tell, these lines come from Gerardo's original version.
