Or Ada.Sequential_IO, instantiated for Character (or
Storage_Element, etc.) which seems to me the best match to the
original C program. However, Sequential_IO has the problem that the
standard-input and standard-output channels are not accessible, you
must Open named files.

Here is a copy-input-to-output program with Text_Streams and Character:
with Ada.Text_IO.Text_Streams;
procedure Acopy
is
use Ada.Text_IO;
use Ada.Text_IO.Text_Streams;
Input : constant Stream_Access := Stream (Standard_Input);
Output : constant Stream_Access := Stream (Standard_Output);
Item : Character;
begin
while not End_Of_File (Standard_Input) loop
Character'Read (Input , Item);
Character'Write(Output, Item);
end loop;
end Acopy;
