Unfortunately no. This code has been there for quite a while. The issue is 
basically that we were doing performance analysis of ausearch/report and 
libauparse. We found that the integer to string lookups were causing a 
performance hit. Mirek wrote some code to turn these from a serial search into 
a sorted list that I think are now searched using a b-tree algorithm. So, at 
compile time what happens is these tables are sorted so that later they are 
fast. This improved performance quite a bit.
