But the source code is legal. So it has to compile it. But
it does give a warning. In Ada, the practice is to keep working
on the code until one gets a clean compile. By clean, it means
no warnings.
I think we are arguing about semantics here. For me, the compiler
did detect this at compile time, and issued a "message" to the user.
That was the point.

Again, I am not a programming language lawyer. But legal code
should compile. Error should be generated only if the code is
not confirming to the standard. So I do not think this should be
an "error" but only a "wanring".
