Dear Guys,
(specially Satoshi:)

	Does the following make sense?
	The directive name needs polishing and the informational
text too. However, does it cut it?
	At least, it might help decrease the amount of
patching needed around. Besides, the best part, being optional.
	Furthermore, I really think -e should be avoided for
both gmake and make.

MAKE(1)
     -e      Specify that environment values override macro assignments within
             makefiles for all variables.

MAKE(1L)
       -e   Give  variables taken from the environment precedence
            over variables from makefiles.

	It might touch things we do not want touched.
	Just a thought.
