It's not QUITE a pure Ada perspective (IMO) ... that would involve the 
Ada compiler system tracking and automatically compiling all necessary 
dependencies.

That's what gnatmake or gprbuild do - where some languages require 
Makefiles or other out-of-the-language means to manage the dependencies.

However in this case the dependency is injected by specific versions of 
the compiler, behind Ada's back so to speak, so the Ada compiler can't 
track it for you. Even if it's written in pure Ada, the separate compile 
and linking steps are still just a workaround until the compiler gets 
fixed.
