c++ mark enum value as deprecated?

Question

Is it possible to mark an enum value as deprecated?

e.g.

enum MyEnum {
    firstvalue = 0
    secondvalue,
    thirdvalue, // deprecated
    fourthva

You might be able to use some macro hackery.

enum MyEnum {
    firstvalue = 0
    secondvalue,
    real_thirdvalue, // deprecated
    fourthvalue
};

template 
struct real_value
{
    static MyEnum value()
    { 
        1 != 2U;  // Cause a warning in for example g++. Leave a comment behind for the user to translate this warning into "thirdvalue is deprecated"
        return v;
    }
};

#define thirdvalue (real_value::value());

This won't work in a context when a constant is needed.
