Yes, it could be possible.

Moreover, I wonder if there are any program using old-style (libc5
style?) structure today.  Some ports do not use IPC_64 flag at all,
but I think they are using new-style structure anyway.  I suppose
killing all old-style crap from both kernel and libc will not hurt
many people.  (Who knows?)
