I've been able to do similar with (untried in this case):
* ( int ** ) & ip.miscitems = &miscitems; /* Try casting on the left. */
...
That solution may introduce unnecessary reference-and-dereference instructions,
depending on the optimization level at compile time. I find it far easier to
coerce the subject to the target, in this case with a simple (char **) in ILP32
mode. IMHO that should make the assignment much simpler for the compiler to
generate optimally, and for the next programmer looking at it to decipher.
ip.__miscitems = (char **)&miscitems;
YMMV, and TMTOWTDI.
