Yeah, if it were up to me to decide this, I think we should go for 32 bit
offsets. 64k just aint enough these days. One of the things I was really
hoping for when the -mbaserel stuff was incorporated into gcc, was to be
able to make sharable versions of the _good_ shells (bash, tcsh), emacs and
the like. This is unfortunately impossible with only 16 bit offset.
How about making the whole concept of sharable libraries only available on
68020+ machines ?

(Guess I got a few enemies there...)
