This is for example one instance of a binary incompatible change.  If we 
want to be serious about stability in the future we need to watch out for 
these things.

(In this case the problem is, that this all defines an enum, hence 
numbers with a name and an association between those numbers and the 
strings.  The change above assigns to all strings behind the removed item 
a number one less than before.  So binary programs that e.g. used 
PRODUCT_REGISTER_TARGET to lookup attributes will now look for string 
"product:regrelease")  This doesn't yet matter with just the static 
library, when the applications are also recompiled with the new header.


Ciao,
Michael.
