I had the thought the deprecated feature could be a way to track or 
inquire about the home scope of particular identifier names. It should 
be the deprecated message follows the identifier around as long it 
exists. This being, perhaps, a use making the the feature more worthwhile.

Again I set up a scene hierarchy of:

     A.pov -> B.inc -> C.inc

Where I used #declare or #local I made use of the deprecated feature. In 
A.pov, for example, I set up identifiers A and B:

#declare deprecated "Referenced A 'declared' in file A.pov" A = "A\n"
#local deprecated "Referenced B 'localed' in file A.pov" B = "B\n"

and so on into C.inc where I added this #local declaration of A which is 
entirely local to C.inc:

#local deprecated "Referenced A 'localed' in file C.inc" A = "A_l\n"

What happens might or might not be the same bug. I'm not going to 
further debug and try and work up a fix. The 'deprecated' feature is 
going away in the povr fork.

For v3.8 b2:

Bug 1.
The #local 'A' creation in C.inc has nothing to do with the global 'A', 
however, POV-Ray issues the deprecated message as if the global 'A' in 
A.pov is being referenced. It does this whether or not the #local in 
C.inc of A uses the deprecated feature itself.

Bug 2. The follow on reference to the local A in C.inc returns the 
correct local to C.inc 'A' value, but no deprecated message at all - 
though I specified one. Other #local use where there is no name 
collision with a more global identifiers to work fine with the 
deprecated feature.

Aside: I previously mentioned the deprecated feature is not working with 
the 'global' and 'local' pseudo dictionaries in this thread:

Lastly, I've attached a tarball with the code I was using that exposed 
the bug(s).
