Those lines are not valid C++, since no typedef name is provided. Sun C++ accepts them as an extension, but issues a warning because the code is not valid.
Examples:
typedef int Int;
Int is declared to be a synonym for int.
typedef int;
Invalid: no name is provided as a synonym for int.
enum Foo { a, b, c};
Foo is declared to be an enumerated type with enumerators a, b, c.
Typedef Foo Bar;
Bar is declared to be a synonym for Foo
typedef enum { d, e, f } E1;
E1 is a synonym for the unnamed enumerated type with enumerators d, e, and f. This is a C style declaration, which serves no useful purpose in C++.
typedef enum E2 { g, h, i } E3;
E2 is declared to be an enumerated type with enumerators g, h, i, and a synonym E3.
typedef enum E4 { j, k, l };
Invalid declaration. No name is provided as a synonym for E4. Remove the "typedef" and you have a valid declaration of E4 as an enumerated t ype.
