Right. Given that the only cost of allowing the generated code to
work in both 26 and 32 bit modes is a single MOV instruction your're
probably right.

Doing this would have the further advantage that we could build
future releases as 32 bit so we don't need to maintain two builds
as users move to 32 bit environments.
