Patching from floam with some edits by myself:

I was working on a patch earlier to fix some more things up to be more
modern, and I added a couple lines from that cleanup patch I showed you
on irc. Some commented code was removed, some stuff was made to not be
broke (old head usage), the makefile should install things better, and a
a few GCC warnings were gagged. I also attempted to version it but
you'll probably want to change that to whatever versioning rules you
decide on using.
