Unstandardized and undefined are two different things. If the standard
says "this is implementation defined AKA undefined" is just as clear
and unambiguous as saying "this is defined so and so". Both statement
are equally clear as to determine if a code conforms to the standard
or not. The purpose of a standard is not to define everything but
define clearly certain things and make it equality clear what is not
defined and is left as an implementation detail.
