Sam Mize says

<<I believe he's saying that most implementations of Ada don't
warn you which other library units your change has just
obsoleted.  You have to go compile or otherwise check each
module and see what's become obsolete.  This works with Eiffel
too, according to the Eiffel users.

In fact, some Ada toolsets DO provide this capability.  The
Rational environment maintains library units in different
states from "text" through "object code has been generated."
I believe it has a capability to tell you what other library
units depend on a given unit, so you can tell who you're
going to screw up if you edit something.>>


YOu certainly don't need anything fancy if that is all you want. With
GNAT, the gnatls utility will provide this information (it is quite trivial
to get, you just check alis of other files to see if any of them have a 
dependency reference to the file you just edited.

Certainly DEC Ada has tools that achieve this goal (which is after all
very easy to do!)
