long long int array warning

[Erick Hallick]

Hello,

I am getting a strange warning which I believe is incorrect when declaring 
an array of long long int's.  Consider the following simple code:

#include <stdio.h>

int main()
{
  int i;
  long long int a[] =
  {
  1,
  2,
  2000000000,
  4000000000,
  8000000000,
  -8000000000
  };

  for(i=0;i<=5;i++)
    printf("a[%d] = %lld\n", i, a[i]);


  return 0;
}

I get the following error while compiling:

ehallick@netfinity:~ > gcc -Wall test.c
test.c: In function `main':
test.c:11: warning: decimal constant is so large that it is unsigned

However, then I execute the program, it appears that the array has been 
assigned correctly.  Here is the output:

ehallick@netfinity:~ > ./a.out
a[0] = 1
a[1] = 2
a[2] = 2000000000
a[3] = 4000000000
a[4] = 8000000000
a[5] = -8000000000

I've tried casting the constants to (long long int), but that doesn't get 
rid of the warning.  Does anyone know if I'm doing anything incorrectly?

Many thanks in advance,

P.S:
