You should use <iostream> in place of iostream.h. For cout, you can
use
using std::cout;

Two errors in this step (when instantiation of D<char> is done):-
1)C++ does not permit implicit conversion from int type to enum type.
That is you cannot write
enum R{A,B};
R x = 1;

2)basefield is an l-value, that is it is an integral constant, a
lvalue. So you cannot assign
any thing to it.
