"   Ada: An Ada compiler is required to enforce consistency and
 strong type checking across separate compilation.  The concept of
                                                    ^^^^^^^^^^^^^^
 a program library is built into the language, based on separately
 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
 compilable modules called "library units" whose names are part of 
 a hierarchical name space."
 
 GNAT, probably the most popular Ada95 compiler, does NOT use the
 program library model, but uses the code-source model, i.e. the 
 traditional model."

Gnat does have a program library, just as Intermetrics also has
a program library. The library just happens to be implemented as
a series of source code files, and not some mysterious black box
piece of software.

List through the requirements of such a library, and you'll find
that the source code model can meet them.
