So what else is new?  In the following Ada code the "exit" will exit the
loop instead of the 'if' statement:

	loop
		...
		if ... then
			...
			exit;
		end if;
		...
	end loop;

In C, 'break' exits switches and loops.  Not ifs.

unless the whole thing was enclosed in a loop, which would be exited
instead of the 'if'.
