It looked okay to me.  This might make a good test case for compiler
validation.  So long as you invoke offsetof() correctly, which it
appears that you did, offsetof() is supposed to expand to an integral
constant expression, which is a subset of "arithmetic constant
expression", which is one of the allowed initializer classes.
