I think that's the direction we're heading.  I guess now is as good a time
as any to tell everyone :-)

Basically, we're going to be temporarily turning off -fexceptions for C
(hopefully starting with the next snapshot).  The basic idea is to turn
it off so the C folks won't pay the EH penalty until such time as we can
get the overhead down to something acceptable to most C programmers.
