    I have no idea what Elf64_Sxword even is.  Some kind of structure or
    elf type?  Where is it supposed to be defined?
Okay, I got it backwards.  The other BSD's added Sxword after you forked
from FreeBSD4, as Peter says.  How do you feel about updating DFly to use
the more current elf definitions?  Would it be a huge job?
