Re: forward declaration of an enumerated type

Hi Ben,
Thank you very much for your pointing out.

I am awfully sorry for this bad reply. I misunderstand the conception
before.
No matter struct and enum types can be forwarded declared. I
performed a test for clarifying my mistake and hope that it helps for
this issue.

//=====x.h=============
#pragma once
struct X {int a;};

enum Color{
Red = 0,
Blue = 1,
Green = 2
};

//======y.h==============
#pragma once

struct X;
enum Color;
void print(X& x);
void print(X& x, ENU enu);
