Yes.  The point is to have one configuration for 32-bit machines and one
for 64-bit, not three possible configurations on 32-bit and four on
64-bit.

I don't actually envision changing the C code much at all; we might want
to resurrect the old code at some point.  I just want to reduce the number
of supported configurations.

Agreed.  It'd still be possible to manually force this, it just wouldn't
be a documented/supported configuration.
