I assume if SmartEiffel assumed that gcc was the backend and therefore
left some optimizations to the C compiler, it would be far less
optimal compiler.

Just assuming the C compiler will take care of an issue, isn't a safe
bet. That was the point you wanted to proof. Brian didn't want to
trust the C compiler.
