/* Routines for accessing command line arguments from both the runtime
library and from the compiler itself. In the former case, gnat_argc
and gnat_argv are the original argc and argv values as stored by the
binder generated main program, and these routines are accessed from
the Ada.Command_Line package. In the compiler case, gnat_argc and
gnat_argv are the values as modified by toplev, and these routines
are accessed from the Osint package. */
