Or limit it to values above -15? What does the manual say?

Thanks; I've increased the range now to 24bit from 15 for db() via Pow2. Also in the process, I discovered two outstanding static tables in aops.c, which we hadn't tracked down way back in 2004-5. I have moved them to be instance-based and modified the functions and macros to create and access them.
