Otherwise, you could have a stale refcounter program lying around after an svn up.
Alternatively the refcounter could be moved to is own rm line and commented as removing legacy build objects.</pre>

Since it has benefit only for developers looking to fix bugs, I'm proposing it for Asterisk 1.8+. The removal of refcounter should be done in trunk only.
Asterisk uses reference counted objects. A lot. As their use has spread, the bugs related to reference counting errors has grown as well. Central to resolving reference counting issues is the usage of REF_DEBUG; unfortunately, REF_DEBUG has had several problems:
(1) It could not be enabled through menuselect
(2) When not enabled globally, updates to objects were often lost, resulting in insufficient data to resolve problems
(3) The format of the ref debug log file was not suitable for parsing
This patch changes REF_DEBUG in the following ways:
(1) It makes REF_DEBUG a meneselect item when Asterisk is compiled with --enable-dev-mode
(2) The ref debug log file is now created in the AST_LOG_DIR directory. Every run will now blow away the previous run (as large ref files sometimes caused issues). We now also no longer open/close the file on each write, instead relying on fflush to make sure data gets written to the file (in case the ao2 call being performed is about to cause a crash)
(3) It goes with a comma delineated format for the ref debug file. This makes parsing much easier.
(4) It throws out the refcounter utility and goes with a python script instead.</pre>
