Interesting. What is the difference to the following (what we have been
using for some time)?

   package Naming is
      case OS is
         when "UNIX" =>
            for Body ("Plugins.Internal_Load")
              use "plugins-internal_load-unix.adb";
         when "Windows_NT" =>
            for Body ("Plugins.Internal_Load")
              use "plugins-internal_load-windows.adb";
      end case;
   end Naming;

The two Internal_Load being "separate" procedures for package body
Plugins.

Are the pros and cons versus the Implementation attribute above (which
I didn't know about until now)?
