Turning off exceptions cut a 7 meg program down to 5 megs with g++, and a
4 meg program down to ~3.5 with VC.  (Numbers aren't exact--tests were over
a year ago--but the order of magnitude is correct.)  That's just too much,
in my opinion.  I'm developing for memory-limited environments (not 128k
embedded, but not half-gig-desktop, either: two megs matters), which influences
my outlook, but I wouldn't enjoy all code on my workstation being 20% bigger,
either.
