By using a bitmask I think there is an implication that the flags can
be combined...
Perhaps it is not a problem today, but later you may want more flags. e.g.
#define SUBSCRIPTION_REL_STATE_READY 0x02 /* READY relations */
then the bitmask idea falls apart because IIUC you have no intentions
to permit things like:
(SUBSCRIPTION_REL_STATE_NOT_READY | SUBSCRIPTION_REL_STATE_READY)
IMO using an enum might be a better choice for that parameter.
