Function prototype counted as global variable.

Erroneous code

int (*grid(void))[8]; 

Additional infos
norminette 3.3.55

Notice: GLOBAL_VAR_DETECTED  (line:  15, col:   1):	Global variable present in file. Make sure it is a reasonable choice.
Error: GLOBAL_VAR_NAMING    (line:  15, col:   7):	Global variable must start with g_

int (*grid(int agrid[5][8]))[8] {

   // ... computation etc
    return agrid;
}
