However existing code does have IRIX N32 emulations
structure, since its there I presumed it's working. I
think N32 will be of immediate interest to many
(atleast to +me).

O32 is already in place. some syscalls are working, i
guess that is the reason i am able to use N32 "sh". 

do we need to separate _N32 & _N64 support options??
Because I think the ABI layout is not different
between these two.

thanks.
girish.
