Would it work to provide storage for it in a static function inside the 
struct?  If you need to keep the same syntax you could create a proxy 
class to access it, something like this (untested):

struct myenum
{
    static struct
    {
    private:
        static char * namestorage (  )
        {
            static char namearray[] = { "yadda", "stuff", "etc" };
            return namearray;
        }

    public:
        char * operator [] ( int index )
        {
            return namestorage (  )[index];
        }

    } names;
};
