	I think I saw in an earlier message that you were going to shoot
for a wastage of 0 bytes.  I think it might be wiser to accept anything
with 4k or so.  Although I don't really see how it could happen, it'd be
quite horrible to find a system where the amount of puresize increased a
bit on a subsequent build, and it needed to rebuild a 3rd time.  I guess
I'm leery of any iterative dynamic process that has 0 tolerance.

	Certainly seems great.  Now if it would automatically rebuild,
w/o me having to wake up to type `make' again... :)
