I tought the UNIX O_BINARY logic was only for CYGWIN and wondered what 
other UNIX that could be.
Ok, so we'll have to use
#if defined(WIN32) || \
   (defined(UNIX) && (O_BINARY != 0) && !defined(__CYGWIN__))

or make the call slower by doing a dynamic textmount check.
But I really don't want to do that.
