What do mpz_powm and mpz_powm_ui return when the caller requests 0^0?
It is exponentiation in a ring, one should think of as quoting with the
last argument m, i.e., Z/mZ. When m = 0 this is plain old Z.
Is that not what you observe?
Are there restrictions on the value of the last arg (modulus)?
[can modulus be 0, 1, negative?]
The sign of m does not affect the result.
