Initialization error in VS2010 during array initialization

I need to assign an array of 6 arrays and its type set[maxSetLength]

#include "stdafx.h"
#include <stdio.h>
#include <stdlib.h>
#define maxSetLength 129

typedef short int set[maxSetLength]; 

int _tmain(int argc, _TCHAR* argv[]){
int i;
set a={0},b={0},c={0},d={0},e={0},f={0}; // Assigning 6 Sets (Arrays) initialized by zeros
set sets[6]={a,b,c,d,e,f}; //Inserting All Sets into one Array (Array Of Arrays)
}

CodeBlocks compiles without errors; in VS2010, this is not so, and these are errors:

6 times

error C2440: 'initializing' : cannot convert from 'set' to 'short'

6 times

IntelliSense: a value of type "short *" cannot be used to initialize an entity of type "short"

You need to use pointers (they are complex in C). Try the following code (I added some debugs, so change them to 0):

#include <stdio.h>
#include <string.h>

#define maxSetLength 129

typedef short int set[maxSetLength]; 

main()
{

int i;
set a={55},b={0},c={0},d={0},e={0},f={66}; // Assigning 6 Sets (Arrays) initialized by zeros
set sets[6]={*a,*b,*c,*d,*e,*f};

printf("%d\n", sets[0][0]);   // should be 55
printf("%d\n", sets[0][5]);   // should be 66

}
