yes we use the PTR() macro to access the _mp_d field.

I'm not aware of those functions. Having public functions to access the mpz_t
fields would be useful.
Btw, in gmp_xrealloc_limbs you call gmp_reallocate_func with old_size=0,
which makes the memory management check in the MPFR tests fail. Please
could you fix that?
gmp_xrealloc_limbs (mp_ptr old, mp_size_t size)
assert (size > 0);
return (*gmp_reallocate_func) (old, 0, size * sizeof (mp_limb_t));
