| Many, many people have made address 0 result in an address fault (who said

| it work, simply to placate stupid programmer, such as you appear to be.
| Frankly, I would *much* rther have my OS complain, so I can track down the
| error (for that's what it is) during development.  (SCO, for example, has
| address 0 readable and writable, because too many applications people
| bitched about it.  I prefer having a core dump, myself.)
+---------------

Whatever happened to (System V) ld using a default ld script in /lib?  Plexus
System V did this, and it was trivial to change it from the default to not
mapping page 0 (they even provided a script for this, and a special ld option
that used that script instead; but changing the default script worked fine).
