See POSIX:
« In historical implementations the value of O_RDONLY is zero. Because
of that, it is not possible to detect the presence of O_RDONLY and
another option. Future implementations should encode O_RDONLY and
O_WRONLY as bit flags so that:
O_RDONLY | O_WRONLY == O_RDWR
»
So please see the issue with the POSIX commitee first :)
