You could use OS_Lib.Read. I believe it's portable to non-GNAT Ada
compilers, and I believe its license is pretty liberal.
I haven't looked at any of these benchmarks. It sounds like this one is
measuring speed of text input. Is that intentional? If so, then
Text_IO is the appropriate thing to measure, because that's the standard
way of doing it in Ada. This is one of the few areas where C is simply
better than Ada.
Of course, as somebody pointed out, input speed is irrelevant for many
programs. But I don't think Ada compilers typically use their own
Text_IO to read their input!
