There was a long tinkering process at farbfeld about this, but the sad truth is that it's the only way to make the Makefile truly portable. Listing it just as $(COM:=.o): config.mk $(REQ:=.h) omits the dependency on the c-file itself, which incurs that strictly speaking the object file is not depending on the source file, which is nonsense. You don't see strictly Posix compliant Makefiles around very often and most use nasty GNU-extensions everywhere. It is a good idea to go ahead as a fitting example and show how to write them portably.
