I think this was intended as an internal function in mini-gmp, not an
implementation of the _mpz_realloc interface. Hence declared static.
We could add _mpz_realloc (and add mpz_realloc2, which is the
recommended gmp interface).
But both realloc functions would be of quite limited utility when using
mini-gmp, because many of the functions assign the result variable
using mpz_swap, making the caller's allocation irrelevant.
Do you depend on _mpz_realloc setting the result to zero if the value
doesn't fit? Otherwise,
#define _mpz_realloc(x, s)
#define mpz_realloc2(x, s)
might be a good enough substitute for mpfr (but it's not good enough, if
we want to define it in mini-gmp).
