>I see SNAPBUILD_STATE_INCR more as an "offset" (to get the lowest enum value to be at lookup index [0]) than an "increment" (between the enum values), so I'd be naming that differently. But, maybe I am straying into just personal opinion instead of giving useful feedback, so let's say I have no more review comments. Patch v9 looks OK to me. ====== Kind Regards, Peter Smith.
