I don't think that "enum" has to mean "sequential integers", but rather
"an listing of related constants" as defined by Wikipedia:

    An enumeration is a complete, ordered listing of all
    the items in a collection.

Giving a list of related constants a name makes the code easier to
understand, especially when the variables have totally generic names
like "flags".  I'm not saying it isn't possible to figure out what
the possible values of that variable are, by hunting around the code
to see what is assigned to it, but making the code easier to understand
at first reading should have value by itself?

Cheers, Andreas
