With the following Makefile:

The first make invocation produces:

And the second make invocation:

So we are in a situation where:

  1. a makefile is included with the include directive (no -include),
  2. the included makefile is not found,
  3. make finds no rule to produce it and decides not to include it,
  4. make executes a recipe for a prerequisite of the included makefile that incidentally also produces the included makefile,
  5. as the included makefile is finally found make does not fail... but it does not read the included makefile.

This could be considered as contradictory with the documentation:

After all makefiles have been checked, if any have actually been changed, make starts with a clean slate and reads all the makefiles over again.

make should either fail or include the included makefile.
