    Silencing cast-function-type warnings
    
    A lot of code cast function pointer to incorrect types. There is no
    other way but silencing the warning. Follows an example of such cast:
    
    glib/glist.c: In function ‘g_list_free_full’:
    glib/glist.c:223:25: error: cast between incompatible function types from ‘GDestroyNotify’ {aka ‘void 
(*)(void *)’} to ‘void (*)(void *, void *)’ [-Werror=cast-function-type]
       g_list_foreach (list, (GFunc) free_func, NULL);
                             ^
