The old "-use-basis-library false" did have the primitive types in
scope (via the Env.addPrim function) and one could write _prim and
_ffi declarations.  It was useful for writing very small programs.

I'm confused.  It looks to me like this is what happens in the code
you checked in.

Oh, do you mean using the same prefix and suffix in the same basis no
matter what the -basis flag?

I'm still confused.  Do you mean that with your proposed change that
"more of the basis is used than is available" or that that is the case
right now?

Anyways, I'd be fine with having -basis none bind the primitive types,
tycons, and excons, as the old -use-basis-library false did.

Also, since the whole idea of -basis none is to keep the code as small
as possible, I'd vote for adding a call to Posix.Process.exit in the
suffix, but not OS.Proces.exit.
