On the amiga, these modes are exactly the same as the default modes
(without the 'b').

With some operating systems, like msdos, the default modes translate
between CR/LF newlines (which the os uses) and LF newlines (which c
programs use), and you need the 'b' modes to turn off this
translation.  But since the amiga os uses LF as newline, there's no
need to ever do a translation in the amiga version.

So they're there just to be compatible with other releases of the
compiler.
