Not exactly ... since gcc 3.x supports ansi C99 (which permits effectively
to declare your variable whatever you want), ObjC with a gcc 3.x works
that way. What's very strange (to me) is that it let you declare your variable 
anywhere but in a loop !

Thus, the following is authorized :

void myfunction {
        printf ("test\n");
        int i;
        for (i= 0; i < 42; i++) {
                printf ("%d\n", i);
        }
}

but this :

void myfunction {
        printf ("test\n");
        for (int i= 0; i < 42; i++) {
                printf ("%d\n", i);
        }
}

is not authorized in C99 (and so, not in ObjC either)
