So I had tried using a enum name as well, close to what you suggest
here, and still got the "warning: useless storage class specifier in
empty declaration" build warning.

Though trying again, it seems the problem was I was declaring it as
"static enum ...". Removing the static allows it to build w/o warnings
as a unnamed enum structure. Why, I don't know. :P

Thanks for the pointer!
