So SOCK_CLOEXEC is set when loading some .h file, in my case
/usr/include/x86_64-linux-gnu/bits/socket.h which includes:

----------------------------
SOCK_CLOEXEC =3D 02000000,   /* Atomically set close-on-exec
                                                   flag for the new
descriptor(s).  */
#define SOCK_CLOEXEC SOCK_CLOEXEC
-----------------------------

Am I right? (I don't understand the purpose of lines 8-14 in your above lin=
k).

Ok.

Yes, but that should be considered an "human" error :)
