Yes... In your code, and possibly your compiler. :-)

In general, you don't want to forward-declare enums. I'm not sure off the top 
of my head whether the syntax is even valid; even if it is, you shouldn't use 
it. C++ allows the size of an enumerant to depend on the range of values the 
enumeration must be able to hold. To derive this information, the compiler must 
be able to see the definition of the enumeration in each translation unit where 
the enumeration is used.
