Consider the following:

    struct color {
	enum { red, green, blue }   type;
    };

    main()
    {
	struct color favourite;

	favourite.type = red;
    }

If this piece of code is compiled with g++ (1.35.0) or AT&T cfront (1.20)
both compilers complain about `red' in line 10 being undefined or
undeclared, resp.

gcc (1.35.0) and Sun cc compile without problems.

The C++ book by Stroustrup says nothing about an enumerators scope
being restricted.

Is this a compiler bug or a difference between c and c++?

Thanks in advance.
