<<The usual explanation is that the C standard library buffers I/O while many
other languages does not have that requirement. If Ada required that the
stream I/O libraries had to support buffering then Ada would probably be as
fast as C for single character I/O.>>

One more comment here: in GNAT, the I/O sits on top of the C standard
library stream I/O, you get whatever that layer gives you, so from the
point of view of system level access, the situation in GNAT is identical
to that in C. See GNAT reference manual for further details.
