Excuse me. I have a question about Section 3.7 of the GNU Make Manual
Version 3.81 whose title is "How Makefiles Are Remade". It said
"After reading in all mkefiles, make will consider each as a goal target
and attempt to update it." But according to my experience, Make doesn't
only consider and execute the rules whose target is the Makefile itself,
but also the rules with Makefile itself as one of the prerequisites. So
I suggest it should be mentioned in the manual. Thank you very much.
