mpz_powm_ui () for 5.1.2

Hi, developer! I installed MinGW, then 'mingw-get install mingw32-gmp' , got the gmp 5.1.2 properly. mpz_powm_ui () give a wrong calculation as below (compared and confirmed by Python): // 2^(c-1) = 1 mod c^2, c = ? #include #include #include int main() { printf("hello, world!
