 7 Another ambiguity arises in a parameter-declaration-clause of a  func-
   tion  declaration,  or in a type-id that is the operand of a sizeof or
   typeid operator, when a type-name is nested in parentheses.   In  this
   case,  the  choice  is  between the declaration of a parameter of type
   pointer to function and the declaration of a parameter with  redundant
   parentheses  around  the declarator-id.  The resolution is to consider
   the type-name as a simple-type-specifier rather than a  declarator-id.
   [Example:
           class C { };
           void f(int(C)) { } // void f(int (*fp)(C c)) { }
                              // not: void f(int C);
