I didn't study the code emitted by C18 to see if it was optimal, but
extended mode code was definitely smaller than using standard mode
when access RAM wasn't part of the picture.

I'm sure it will depend on the application, but access RAM will always
provide a code size win, while the benefit of smaller stack code is
probably highly dependent on the application's use of function calls
and parameters.
