Well not much work. I asked Sebastian if you knew
and he said you did.  Didn't fix it. :)

That matches what I thought.

I figured as much since I hadn't heard much from you either.

I'm still suffering backlog from the move, spider bite, and
the class. I still am also not used to the new office.  Yesterday
I spent 20 minutes looking for why a board wouldn't load
executables and then remembered I had only set the board
on my desk -- hadn't put a network cable on it yet. LOL!

Looks like we are heading for a new spin of the 4.10 tools
soon.

  + drop - DMISSING_SYSCALL_NAMES from configure.host
  + ALIGN issue not being 8 on SPARC
  + inttypes.h warning

Oh well.
