Maybe changing the prototype of mpq_cmp_maybe_z to int mpq_cmp_maybe_z (mpq_srcptr op1, const void *op2, int op2_is_mpz) so that we can pass to it either an mpq_srcptr or an mpz_srcptr, then replace occurrences of NUM(op2) with ((mpz_srcptr) op2), and occurrences of DEN(op2) with DEN((mpq_srcptr) op2)...
