The order of the terms in ParenType require implementing a special
case for ParenType. This case handles only the following:
<type> ( * id [ .* ] ) ( params )
i.e., a function pointer or an array of function pointers, and will fail
for any other cases. This is similar to the function used to print
ParenType in Pretty_print_c.
