Hm, don't think that's the (only) issue here. Basic .c -> .o  
dependencies appeared to work okay for me. -MMD might help for  
included files? I think the Forth dictionaries are part of the problem  
though. At least that was the problem I ran into some time ago.

Another dependency issue that's been annoying me is that the version  
files don't get updated. I was considering a patch that regenerates  
them as part of (not dependency of) the versions target. Alternatively  
we could print the Git hash or SVN revision rather than the ever- 
changing time.
