commit d3d838cc2630c416aff8d0b0d0bc1e44a5cf81dc
Author: Sebastian Huber <sebastian.huber@embedded-brains.de>
Date:   Mon Oct 8 14:27:38 2018 +0200

    Make some standard open() flags visible
    
    Make the POSIX O_CLOEXEC, O_NOFOLLOW, O_DIRECTORY, O_EXEC, and O_SEARCH
    open() flags available also to non-Cygwin systems.
    
    Make the BSD/glibc O_DIRECT open() flag  available also to non-Cygwin
    systems.
