C++ code will not compile

[Greg Davis]

Hi guys,

I got this code from some forums:

#include <iostream>
using namespace std;
#include <gmp.h>

int main()
{
mpz_t x;
unsigned int y=126976;
mpz_init(x);
mpz_set_ui(x,4294967296);
cout << "\nx: " <<x << endl;
cout << "\ny: " <<y << endl ;
mpz_pow_ui(x, x, y);
cout << "x^y is  " << x << endl;
mpz_clear(x);
}

but when I try to compile it I get:

bignum.cpp:11: error: integer constant is too large for "long" type

Can anyone help me figure out why it does this? It seems to compile fine
on his computer.

Thanks for any help.
