Paul just explained that there is a way to make a variable seem like
it's set on the command line, when in fact it's not.
Here's a simple Makefile:
install:
@echo $(alpha)
@echo $(origin alpha)
From the shell:
export MAKEFLAGS="alpha=not-set-on-command-bline"
make
not-set-on-command-bline
command line
It's not a normal way of using Make, but it does deserve to be
examined.
