There are the obvious examples. The harder cases to catch deal with
intent. What did the developer really intend this construct to do.
A growing problem is 32->16. People are starting to want to port
software written in a 32 bit environment to smaller processors.
Should I stick my neck out and claim that 16->32 is not a major
problem any more because most of the conversions have been made?

You might find some interesting pointers in various pages at
www.knosof.co.uk. However, this site does promote a commercial tool,
so it does not get involved in too many low level details.
