Cenum is not a subtype of Integer

[melonedo]

With respect to JuliaLang/Downloads.jl#134, in the C language, enum is just an alias for some integer type. However, CEnum is not a subtype of Integer, and it does not support all integer methods, zero for example.

Integer is a Number, I don't think enum is a number because we usually use it in the style of a name, not a number(even though there is a number behind that name).

In practice, you could explicitly convert a Cenum to a Integer, so it doesn't matter whether Cenum is a subtype of Integer or not.
