I installed MinGW, then 'mingw-get install mingw32-gmp' , got the gmp
5.1.2 properly.
The last release of the library is 6.1.2 .
unsigned long long c = 10307e7 - 1; // change c,start point
mpz_set_ui(b,c);
mpz_mul_ui(b,b,c);
mpz_powm_ui(d,a,c-1,b );
Look carefully at the documentation of the three mpz*_ui functions you
use.
They take an _unsigned long_ as their _ui argument.
You pass an _unsigned long long_ variable, the compiler implicitly
casts.
Does "mingw32" means unsigned long is a 32-bit type?
You should use an mpz variable to store values exceeding 2^32...
