Yup, I'll just do that. I'll fix up my patch to be more complete (ie the a.out-core.h removal Jann pointed out). I'll talk about removing a.out support entirely in the commit message. I'd be ok for that to be a total removal, but maybe there are some architectures that still have that as a "main" format? Or I could just apply your patch after removing the core-dumping. Comments?
