With implicit rules, there's no precedence.  You can have several
different implicit rules that can be applied to create the same
target.  Make will choose one of them, but not necessarily the last
one it sees.

The original makefile *did* include a rule to produce foo.o given
foo.cpp.  And that is what important, as far as Make is concerned.
