Thanks.  I've got these on fixes now, I'll send them up tomorrow morning 
assuming the autobuilders don't find any issues.  Like I said in the 
other thread I wasn't getting these allmodconfig failures, so if there's 
an easy way to reproduce them I'd be happy to add it to my setup -- I 
don't really know anything about GCC plugins, I'm just using Debian's 
toolchain for my Linux test setup (haven't gotten around to merging it 
with my GCC test setup, and it's been a decade so I guess I should stop 
pretending that's going to happen ;)).
