Mingw is the only known platform that lacks O_NONBLOCK (possibly
via the alternate spelling O_NDELAY).  But mingw also lacks any
files where open() needs to enforce non-blocking behavior, and
lacks openat(), so it is relatively simple to provide a non-zero
flag.  A future patches will make use of O_NONBLOCK for pipe2.

* modules/nonblocking (Depends-on): Add open.
(configure.ac): Set new witness macro.
* m4/fcntl_h.m4 (gl_FCNTL_H_DEFAULTS): Provide default for it.

Run the new "make update-copyright" rule.

* doc/posix-headers/fcntl.texi (fcntl.h): Document that
O_CLOEXEC is now defined to 0 if it is not defined, like other flags.
Also, O_EXEC is now defined to be O_RDONLY if O_EXEC is not defined.
Similarly for O_SEARCH; this last was already true, but not documented.
* lib/fcntl.in.h (O_CLOEXEC): Define to 0 if not defined.
* lib/dup-safer-flag.c (O_CLOEXEC): Remove now-useless #define.

Likewise.

is zero, not whether it is defined.

* lib/progreloc.c (find_executable): Use O_EXEC rather than O_RDONLY.
* lib/open.c (open): Check for O_SEARCH as well as for O_RDONLY.

Use the same procedure as for 2009, outlined in
http://thread.gmane.org/gmane.comp.lib.gnulib.bugs/20081

open(".",O_WRONLY) used uninitialized memory to decide whether
to succeed or fail - never a good idea ;)
