Yeah, I was really disappointed to discover the broken gcc case Arnd
had while I was testing the new ..._AUTO option. I thought I was going
to be able to throw away a whole bunch of the complexity too. :( And
this was on top of the recent discussion about raising the minimum gcc
level to a place where there wasn't any need for the "old broken gcc"
stack-protectors checks. But, no, that would have been too easy. :(
