You can mark an enum "bitwise" (by making all of it's values be "bitwise"), and it will be considered a type of its own, yes. But then you also cannot do arithmetic on it (which _usually_ is what you want, but not necessarily always).
(You'd also need to pass in the "-Wbitwise" flag to sparse, to get the checks).
By the time you mark something "bitwise", you don't even need to use an enum, btw. You can just do a regular integer typedef and mark the typedef to be "bitwise" - that generates a unique type right there. That's what the endianness checking does.
