In <https://sourceware.org/ml/libc-alpha/2014-06/msg00413.html> I noted
that I presumed the exclusion of IFF_* values not fitting in a "short"
flags field was deliberate.
Can you elaborate way? Do you fear that we might end up with an ABI
change if the enum promotes to int, not short? But doesn't do it that
already, due to the value IFF_DYNAMIC = 0x8000?
