Need to know the reason why GCC able to compile

[naveen yadav <yad.naveen@xxxxxxxxx>]

Dear All,

I am checking below code on gcc 4.4 and gcc 4.6

Below Code compile well.
#include<stdio.h>
int main()
{
struct a{
        int c;
        int b[];
        } d;
return 0;
}

Fail:

#include<stdio.h>
int main()
{
struct a{
        int b[];
        int c;
        } d;
return 0;
}
test.c: In function âmainâ:
test.c:5: error: flexible array member not at end of struct
