Sebastian Huber d3d838cc26 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.

Corinna Vinschen 0aa99373c1 Cygwin: fcntl.h: Define O_TMPFILE and implement it 
Difference to Linux: We can't create files which don't show up
in the filesystem due to OS restrictions.  As a kludge, make a
(half-hearted) attempt to hide the file in the filesystem.

Yaakov Selkowitz d2df6d381b Feature test macros overhaul: fcntl.h 
Most of the !_POSIX_SOURCE code is BSD, although ironically some were
added to POSIX.1-2001.

Use the ATFILE conditional for most of the *at functions, except
futimesat which is GNU.
