Hi Corinna, thanks for the prompt response.

I tried this and it had no effect.
I added the O_BINARY and linked with /lib/binmode.

Is there some other library I should now exclude? I ask as since there were no
unresolved symbols before I added /lib/binmode.o, the link is picking up
whatever symbols are in binmode.o from somewhere else.
