+
+ dtotimespec: new module
+ * lib/timespec.h (dtotimespec): New decl.
+ * lib/dtotimespec.c, modules/dtotimespec: New files.
+
+ * lib/timespec.h (timespec_sign, timespectod): New inline functions.
+
+ pselect: new module
+ * lib/sys_select.in.h: Include <signal.h>, for 'sigset_t'.
+ (pselect): New decls.
+ * m4/sys_select_h.m4 (gl_HEADER_SYS_SELECT): Require AC_C_RESTRICT,
+ since the standard pselect decl uses 'restrict'.
+ (gl_SYS_SELECT_H_DEFAULTS): Add defaults for GNULIB_PSELECT,
+ HAVE_PSELECT, REPLACE_PSELECT.
+ * modules/sys_select (sys/select.h): Substitute GNULIB_PSELECT,
+ HAVE_PSELECT, REPLACE_PSELECT.
+ * lib/pselect.c, m4/pselect.m4, modules/pselect: New files.
+
+ 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.
+ * modules/sys_select (Files): Add m4/sys_socket_h.m4, for
+ gl_PREREQ_SYS_H_WINSOCK2.

+
+ pipe2: fix C89 compile problem
+ * lib/pipe2.c (pipe2): Avoid C99 array initialization.
+ Reported by Bruno Haible.
+
+ pipe, pipe2: don't corrupt fd on error
+ * lib/pipe.c (pipe): Leave fd unchanged on error.
+ * lib/pipe2.c (pipe2): Likewise.
+ * doc/posix-functions/pipe.texi (pipe): Document cygwin issue.
+ * doc/glibc-functions/pipe2.texi (pipe2): Likewise.

+
+ mmap-anon: do not use regular expressions inadvertently
+ * m4/mmap-anon.m4: Remove trailing period from strings sought
+ in the output.
+

+
+ 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.
