Prior to the paging release of System V for the VAX (S5R2V2), S5 UNIX
suffered from the same problem as Berkeley UNIX - it allowed you to
reference location 0. By default, it still does, but there is a linker
switch to build an executable image with no page 0. John Bruner of Lawrence
Liverwurst Laboratory posted a set of kernel and linker changes to 4.2BSD
to make it support no-page-0 executables also.
