For all implementations?

I see that Ada.Command_Line.Command_Name returns the name of the
program that's been run. On Gnat at least it all makes sense. Compared
to C++ (MSVC) on Win32 for:

printargs.exe 1 2 3

I get..
               Ada            C++
Argument Count 3              4
command name   printargs.exe  equiv. to argv[0]
argument 1     1              1
argument 2     2              2
argument 3     3              3

I guess, from the Annotated ARM, section A.15(22) & A.15(22a).
