Here is a directory listing after I ran "make libraries", dependency 
files should now have been created, but they aren't:

good question, since I copied it from the book I don't know. Maybe to 
prevent writing *.d files if there were errors in the *.tmp file? 
Mecklenburg doesn't explain this practice in his book.

Since that's a bad explanation, I removed the $(MV) part and now write 
directly to $@, which makes no difference.
