It's a somewhat weak inference from a footnote in 6.2.5.
Paragraph 4 says:
There may also be implementation-defined extended signed
integer types.
A footnote on that sentence (footnote 38 in N1570) says:
Implementation-defined keywords shall have the form of an
identifier reserved for any use as described in 7.1.3.
I don't see how to make sense of the association between that
sentence and that footnote without an implicit assumption that the
names of extended integer types are implementation-defined keywords.
You could argue that *some* extended integer types might have
different forms, but the standard doesn't mention that possibility.
Furthermore, if size_t is an extended unsigned integer type, then
there must be a corresponding signed integer type. The two types
*could* be called __ssize_t and size_t (where size_t would be an
identifier for something that can't be defined in the standard
language), but I'd find that a bit perverse.
