Assuming (b) is the correct interpretation of Question 3, if within a translation unit at a point where an “integer constant expression” is required to satisfy a language constraint - such as to specify the size of a bit-field member of a structure, the value of an enumeration constant, the size of an array, or the value of a case constant - does the use of the macro offsetof constitute:

a. a constraint violation?

or

b. the use of undefined behavior, which renders the translation unit to be not strictly conforming?

Response

The response to Question 1 makes this a moot question.
