I think we're SOL until I get autotools going.

There is this ugly hack I just barfed up though (kinda what makedeps
from the XFree86 project does):

For now though, I'd suggest just using 'include .depend' and for those
using gnumake, just be sure to 'touch .depend && make depend' before
you get to play.
