O_BINARY is probably not so portable so I'll steer clear of that. You can get around that using #ifdef and #define etc. Or you can link against the Cygwin-provided binmode.o to make all opens binary by default. If you ever plan to distribute your program, you'll pull your hair out with Cygwin users and textmode mounts, so probably better to open in binary mode if you're doing binary I/O.
