G++ compiling with -mno-cygwin and mingw libraries doesn't link


I solved my problem of memory allocation beyond 128 meg of memory by using
the -mno-cygwin G++ flag.  So the program below compiles and executes
properly with
    g++ -mno-cygwin a.cpp

#include <string.h>
int sleep(int a);
int main()
{
char *p;
#define SIZE 450000000
        p = new char[SIZE];
        memset(p, 0, SIZE);
}

However, when I augment it with C++ cout statements (below), I cannot get it
to
link. I get errors to undefined references. I downloaded the mingw libraries
and include files
and while this helps, I still get link errors.

#include <stdlib.h>
#include <iostream>
#include <string.h>
int main()
{
char *p ;
#define SIZE 450000000
        p = new char[SIZE];
        memset(p, 0, SIZE );
        cout << p[244] << endl;
}

 Any help would be appreciated.
