Correct.

Maybe the person writing the makefiles _WANTS_ to include them twice.


If you want to protect against this you can, using the same methods you
would use in C, for example:

    ifndef __INCLUDED_makefile1
    __INCLUDED_makefile1 := 1

    include makefile2

        ... contents of the makefile

    endif

etc.
