If I remember right, that was never the case. Back in the early days
the thing that made compiling apps for suns a bitch was that they were
the platform that shook out all the NULL vs '\0' bugs in all the
software. Reading page zero caused a fault. I remember having this
trouble on the Sun 1's and Sun 2's at Columbia all the time -- got
very good at finding that sort of bug.

Of course, I could just be getting senile.
