It doesn't require historical memory. The test is there is so rules
like

   include lib bin sbin etc:
           mkdir $@ && cd $@ && $(MAKE) -f $(SRC)/$@/Makefile

are not mishandled as inclusions. Use the bmake include syntax; it was
put there for a reason.

If you're trying to write a portable makefile, you should limit
yourself to reliable constructions; I very much doubt your own example
will work reliably in vintage make dialects.
