If you change a trap number, resolving old object and shared library files
ends up with the new trap, not the old one.
If you rename a symbol, you can still link old object & shared libraries.
But this is exactly the same as introducing a new function and has nothing
whatsoever to do with changing system types. It's the cleanest solution
until you decide you don't want the old stuff any more, then you find that
you've got an open32() system call and no open() !
