I don't think that I used -fno-exceptions, but I might have used
-fno-rtti.  On a PC, I don't think that the speed and size
requirements are that low.

That's the way I would go for now.  It's impossible to display
qt/embedded via DirectFB right now.  I've been working on a DirectFB
display driver for qt/embedded (see qte-directfb at directfb.org), but
life has taken over at the moment and it's taking a while to get back
