Since M4 is basically a short CMMI install at 0.2 SBU and 10M disk, I'd prefer 
to see it retained in Chapter 5 and moved.  It may not be strictly necessary but 
the overhead of doing so is really negligible and the more we build using our 
own tools without relying on the host's tools, the better.
