In a Unix system I am designing, I am considering catering to bad
code. That is, like the VAX I propose to make location 0 contain a
readable 0. I think that code which gets ported to a Sun machine often
has to have this kind of thing cleaned up. 

What do people think of this? Is it kind of disgusting?

Just how much code has this problem? Did every program you ported to a
Sun have to be fixed, or 10%, or something in between? 

I'd like to do things right, but I'm also lazy. I think doing this
will save me a lot of work. Have I overlooked anything? The processor
has a relocatable vector area so I can easily map the vector table
somewhere else.
