+ sys_select: don't depend on sys_socket
+ This is so that Emacs doesn't have to drag in m4/sockpfaf.m4 etc; see
+ <http://lists.gnu.org/archive/html/bug-gnulib/2011-06/msg00358.html>.
+ This fix works on GNU and GNU-like platforms, but has not been tested
+ on native Windows.
+ * lib/sys_select.in.h: Include <sys/socket.h> only if native Windows.
+ * m4/sys_select_h.m4 (gl_HEADER_SYS_SELECT): Do not require
+ gl_HEADER_SYS_SOCKET.

+
+ nanosleep: fix integer overflow problem
+ * lib/nanosleep.c (my_usleep): Don't assume signed integer
+ arithmetic wraps around on overflow.
+
+ nanosleep: simplify carrying
+ * lib/nanosleep.c (nanosleep): Use the requested tv_nsec for the
+ first call to the underyling nanosleep, not for the last one.
+ This doesn't fix any bugs, but it simplifies the computation of
+ the remaining delay. Found while auditing integer overflow issues.
+
+ dup2: remove test for existence of fcntl
+ * m4/dup2.m4 (gl_FUNC_DUP2): Use "#ifdef FD_CLOEXEC", not
+ "#if HAVE_FCNTL", in the configure-time test program.
+ This removes the need for the AC_CHECK_FUNCS_ONCE([fcntl]),
+ and therefore speeds up "configure" a bit. Found while
+ adding the dup2 module to Emacs.
