There is another point worth making here.  The Standard must be
subjected to more than mere "linguistic analysis" in order to
understand what it is saying; there is a gestalt that must be
acquired, and it goes beyond the simple expansion of words in
terms of their definitions, just as concepts in general embody
much more than is found in their literal definitions.

For instance, although "(int*)0" does indeed have type "pointer
to int", it does not point to an int.  Moreover, no pointer of
type "void*" points to any datum having type "void"; there are
no void objects in C as specified by the Standard (despite
arguments from some of us that there should be).  Yet simple
elaboration of "pointer to X" might mislead one to think that
such a thing points to X.  These technical terms are used in
subtly tricky ways, and must be understood in the total context
of the language specification.
