The problem is, you HAVE to do this or you run the risk of having
the Makefile break.  "Make" has no business providing variable
semantics for Makefiles dependent on the user's environment.  I
suppose the original reason for this in Augmented Make was to
permit redefining CC for cross-compilation, etc. without having
to edit zillions of Makefiles.  Too bad SHELL is honored too.
