There has got to be a better way to do that.

Incidentally, must we have eval: (c-set-style "gnu") at the bottom of
files?  It just makes emacs slow to visit them (since it has to pause
and show the eval: to the user).

No.  They might be switchable at compile time only.

Yeah, that would make a good new column.

An important meta-point which folks may have missed is I DO NOT HAVE
