Janus/Ada has had that feature by default from the very beginning in 1981. 
Even on 64K Z80 targets. I never understood why GNAT would want to make 
getting them so hard. (Some customers need them turned off for ultimate 
performance, so there needs to be a way to run without them, but most users 
will want them on.)
