Yeah, I think I fixed that fairly soon after I posted the original patch.
A small but important change.

The problem with soft links is (as far as my experience goes), they don't
support dependency tracking by timestamp.  If files are soft linked and I
change one, the timestamp of the link itself does not change, make
fails to notice the change, and things don't get rebuilt.  Of course, I haven't
tried this in practice, so I don't know if it's really a problem or not.
