We've used versions of G++ from 2.95 (which probably doesn't work with
LLVM now) through 3.4. All of them had working operator<<'s. My guess
is that the internix port is broken somehow. I'm sorry, but I don't know
anything about the internix port. You could ask on the
gcc-help at gcc.gnu.org mailing list, as they are probably the right ones to
ask.
