No, the definition uses another Value function.

The call in 40/1 uses

   function Value (Item : in chars_ptr; Length : in size_t)
   return char_array;

from RM B.3.1(35), followed by

   function To_Ada (Item     : in char_array;
                    Trim_Nul : in Boolean := True)
   return String;

from RM B.3(26).
