    The native as on sysV68 cannot handle substractions of symbols (except in
    switch tables), but why do we use substractions here ?  Could exceptions not
    work with absolute addresses ? sysV68 does not support shared libraries,
    it that matters.

Philippe,

I believe, your attempt to support the native system/environment where
possible is very honest; but,  GNU  `as' and  `ld' on this  particular
system  are usable since one year  (at least)! Since we are interested
in the evolution of `GNU Software', I don't think supporting these old
tools is worth the effort, don't you?

Make the GNU system live!
