/* Check if array arguments of ObjC methods are decayed to pointer types
2
   in a proper fashion:
3
     (1) The _encodings_ for the array arguments should remain to be '[4i]' and
4
         such, since this has been the case since at least gcc 3.3.
5
     (2) However, when building the static C functions out of ObjC method signatures,
6
         we need to decay the arrays into pointers (as C does).
7
     (3) If array size is not known (e.g., 'int a[]'), then the type shall be
8
         encoded as a pointer.  */
