...which is almost a direct quote from the GNU make info pages.  Peng,
do you have access to the info pages?  Try running
    info make
or
    info 'gnu make'

and see if either gives you access to the documentation.  It seems
that most of the questions that you've asked here are answered
directly by that documentation.  Are you unable to access that
documentation?
