That is exactly what is happening.

If I do my usual tests and get the looping process started 
and then as the looping runs, monitor the time stamp on 
include/asterisk/version.h, the time stamp chages with the 
time on the system clock. So if it did its first build at 
13:05 and I let the loop continue, the time stamp will 
eventually change to 13:06 and then 13:07 etc..

As I understand it, it seems that since the version.h 
build section has the dependency of FORCE listed and 
FORCE: is balnk, Make will assume that FORCE: has changed 
every time and cause the include/asterisk/version.h: 
section to rebuild every time.

I seem to be able to fix the problem simply by removing 
the FORCE dependency from the include/asterisk/version.h: 
then things seem to build like they should.

I just do not have all the insight that I need in order to 
know for sure when the version.h should and should not 
rebuild.
