Is there a better way? Are enums for array indexes out of fashion?

They are not, but you have declared a variable (reason_types) which you
don't use. You probably meant to create a enum named reason_types, like
this:

enum reason_types {
        NONE,
        BOOTLOADER,
        RECOVERY,
        OEM,
        MAX_REASONS
};

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!
