Re: sun3 port different then many others

Does this mean that the sun2 port is more up to date ?  (it seems to
have that structure rather than the one the sun3 port has)

Also, of interest I see it builds with -msoft_float ... shouldn't it
have -m68881 ?

What would be involved in bringing the sun3 port up to speed with the
way the rest of the ports work ?  (I'm guessin it would be a quite a bit
of work)  Is there any docs on the old structure vs the new structure ?
