That can't be done with an truly opaque FILE; any code that uses those
#defines has to have the underlying type visible enough to know its
size at the very least.

Well, provided your changes don't change the ABI - for example,
switching to "#define FILE void" for stdio would change the ABI on
machines where void * is wider than struct pointers.

Oh, certainly. This discussion has veered off into mostly-theoretical
weeds, and I think we agree on the pieces we're still discussing.
