It seems to me that, because the standard doesn't specify that they are
typedefs, the requirements could be met by having the relevant header
contain the equivalent of the following:
#pragma activate_typename size_t
which activates recognition of size_t as the name of a type. This
differs from a typedef because there is no other name that can be used
for this type. That would be pretty pointless unless size_t has some
properties that differ from any of the basic standard types, which would
odd, but not impossible.
Of course, as far as strictly conforming code is concerned, having
another name that is a reserved identifier is indistinguishable from
having no other name, so I don't see any particular advantage to
implementing it this way - I'm just arguing that it's permitted.
