Good catch. This has been sitting unused for quite some time. I wonder if there is a way to convince the compiler to tell us about unused struct fields. I guess that would imply a view of the whole linked program (though in this case the type is local to a single translation unit). And would probably produce a horrible number of false positives for structs defined in system headers. Possibly static analyzers like coverity could help here, but it does not seem to find this case (or if it did, I could not find it amidst all of the false positives). Anyway, your patch is obviously the right thing to do. :) -Peff
