It was the 'CP=cp -i' that I was referring to. The "-n" should indeed
prevent any commands from actually being run. However, the volume of
output you get from an autotools-generated Makefile with "-n" would make
it easy to miss something important, particularly given that some of the
output could include complex if/then type arrangements.
