The motivation for going this route is that nothing about this type is
machine-dependent, and a further disadvantage of the current
<machine/ansi.h> model is the inability to use the private
(namespace-clean) type macro definition once it's been used to typedef
the public name, which is often desirable for private interfaces in
public headers or ambigousities in a standard concernding the
namespace used by a header.

I do want to use this model (among other things) to make visible off_t
in <stdio.h> in a non-invasive way; I think you'll agree with me that
adding a _BSD_OFF_T_ in <machine/ansi.h> is not the way to address
this issue.
