I was thinking of looking at turning names to varchars/text in order to test
the performance hit [in the first instance]. However doing a
find . -name \*\.\[ch\] | xargs grep NAMEDATALEN | wc -l
gives 185 hits and some of those are setting other macros. It seems to me there
is a fair amount of work involved in just getting variable length names into
the system so that they can be tested.
