Don't forget that Macs use '\r', Unix uses '\n' and Windows systems
use "\r\n".

I don't think he's forgotten that.

But note that the '\n' encoding in C refers to a "new-line" character,
which isn't necessarily an ASCII LF character. On an old Mac system,
I would guess that '\n' is actually the ASCII CR character (either
that, or stdio translates CR to LF on input).

So reading an untranslated MS/DOS file on a Mac would result in bogus
interpretation of 0x0D/0x0A pairs: does the Mac C runtime translate those
into a single \n ? Do unix native text files get read as a single long
unterminated line ? This would happen in both text and binary mode. Is
there even a difference between text and binary more on older Macs ?
