Ok, so after spending the evening learning about just how 
all of this works, I have one last question.

For the section include/asterisk/version.h:, does it 
really have to have FORCE as a dependency? If I leave all 
code in the Makefile as is, and remove the FORCE, then 
evertyhing seems to compile correctly.

It seems that with FORCE as a dependency, it is forcing 
the version.h file to change evertime this section is run. 
In doing so, the .depend section runs, anbd thus you get 
into a loop with the implicit .depend that is setup in the 
beginning of the Makefile.
