Usually it's deep in *** somewhere in the gcc install directory
/usr/lib/gcc/*/include
I thought it's figured out by configure but it doesn't seem so.
Instead you can use template&macro magic to find out:

#include <iostream>
#include <cstddef>

#define PICK(TYPE) void pick(TYPE) { std::cout << #TYPE << '\n'; }
PICK(unsigned int)
PICK(unsigned long)
PICK(unsigned long long)
int main ()
{
  pick (size_t ());
}

I expect you get "unsigned long long", right?
