No, that's worse in that you get run-time errors instead
of compile-time errors.  To wit: 

  typedef struct { ... } va_list[1];
  void foo(va_list s)
  {
    va_list d;
    memcpy (&d, &s, sizeof(va_list));
  }

does not copy the contents of the incoming structure, but
rather the contents of the incoming pointer.

Franz posted a functional workaround.
