    Benjamin> 1. Were these created by BIND? 

They were created by the name server, It uses temporary files to store
in-progress inbound zone transfers. When the zone transfer completes
successfully, the temporary files get renamed to whatever was
specified as the filename for the zone in the slave name server's
configuration. These temporary files might be left behind when a
zone transfer doesn't complete properly: for instance because the TCP
connection breaks.

    Benjamin> 2. Is it safe for me to delete them?

Yes, provided nothing has the files open. lsof is your friend.

Why? Doesn't the 9.3 source compile on your chosen OS?
