First, you must realize that the DOS and UNIX command interpreters (Shells)
will not pass the same thing to the executable program, even for identical
command lines if the command lines contain wildcard file specifications. 
In UNIX, for example, the command line argument *.txt will be expanded to
the list of filenames in the current directory satisfying the wildcard file
specification, while the DOS command interpreter (including Windows 95 and
Windows NT) will simply pass the *.txt to the executable.

In Ada 83, since the LRM does not specify this feature, each compiler
vendor was free to do as he pleased.  The various solutions are not
portable between compilers.

In Ada95, though, the language defines the interface, and in the case of
gnat, at least, the wildcards are expanded by the compiler's implementation
of the LRM's specification.
