Based on ideas from Kim F. Storm <storm@cua.dk>, see
http://lists.gnu.org/archive/html/emacs-devel/2006-12/msg00873.html.
src/w32proc.c (reader_thread): If the FILE_CONNECT flag is set, call
'_sys_wait_connect'. If it returns STATUS_CONNECT_FAILED, exit
the thread with code 2.
(sys_select): Support 'wfds' in addition to 'rfds'. If a
descriptor in 'wfds' has its bit set, but the corresponding
fd_info member doesn't have its FILE_CONNECT flag set, ignore the
descriptor. Otherwise, acknowledge a successful non-blocking
connect by resetting the FILE_CONNECT flag and setting cp->status
to STATUS_READ_ACKNOWLEDGED.
src/w32.h (STATUS_CONNECT_FAILED): New enumeration value.
(struct _child_process): New member 'errcode'.
(FILE_CONNECT): New flag.
(_sys_wait_connect): Add prototype.
src/w32.c (pfn_WSAEnumNetworkEvents): New function pointer.
(init_winsock): Load WSAEnumNetworkEvents from winsock DLL.
(set_errno): Map WSAEWOULDBLOCK and WSAENOTCONN.
(sys_connect): Support non-blocking 'connect' calls by setting the
FILE_CONNECT flag in the fd_info member and returning EINPROGRESS.
(_sys_read_ahead): Add debug message if this function is called
for a descriptor that waits for a non-blocking connect to complete.
(_sys_wait_connect): New function.
(sys_read): Support STATUS_CONNECT_FAILED. Return the error code
recorded by _sys_wait_connect when the non-blocking connect
failed. Don't call WSAGetLastError before a call to set_errno had
a chance to use its value, since WSAGetLastError clears the last
error.
nt/inc/ms-w32.h (BROKEN_NON_BLOCKING_CONNECT): Don't define.
src/emacs.c <w32_daemon_event> [WINDOWSNT]: New global var.
(main) [WINDOWSNT]: Initialize it to NULL. Create the event to
signal clients we are ready for connections.
(Fdaemon_initialized): Use DAEMON_RUNNING.
[WINDOWSNT]: MS-Windows specific code to signal clients we are
ready for connections.
src/lisp.h (DAEMON_RUNNING): New macro, encapsulates Posix and
MS-Windows conditions for running in daemon mode.
src/minibuf.c (read_minibuf): Use DAEMON_RUNNING.
src/keyboard.c (kbd_buffer_get_event): Use DAEMON_RUNNING.
src/dispnew.c (init_display) [WINDOWSNT]: Initialize frames/terminal
even in daemon mode.
nt/inc/ms-w32.h (W32_DAEMON_EVENT): New macro.
lib-src/emacsclient.c (decode_options) [WINDOWSNT]: Don't reject empty
arguments for --alternate-editor.
(print_help_and_exit) [WINDOWSNT]: Don't refrain from advertising
empty arguments for --alternate-editor.
(start_daemon_and_retry_set_socket) [WINDOWSNT]: MS-Windows
specific code to start Emacs in daemon mode and wait for it to be
ready for client connections.
lisp/server.el (server-process-filter): Force GUI frames on
MS-Windows in daemon mode, even if a TTY frame was requested.
lisp/frameset.el (frameset-keep-original-display-p): Don't assume
windows-nt cannot be in daemon mode.
lisp/frame.el (window-system-for-display): Don't assume windows-nt
cannot be in daemon mode.
... for detecting MinGW-w64. _W64 is not specific of MinGW-w64, it is
defined for compatibility with MS VC++.
* nt/inc/ms-w32.h: Define MINGW_W64.

* nt/addpm.c: Use it.

nothing useful.
[WINDOWSNT]: Include w32heap.h.
(init_buffer): Always allocate new memory for buffers.
src/emacs.c: Remove mmap_set_vars calls.

configure.ac (C_HEAP_SWITCH) define for different values of
dumped heap size depending on 32/64bits arch on Windows.
Don't check for pthreads.h on MinGW32/64, it gets in the way.
Use mmap(2) for buffers and system malloc for MinGW32/64.
configure.ac: Read $srcdir/nt/mingw-cfg.site when $MSYSTEM is
"MINGW64" as well.
nt/inc/ms-w32.h (pthread_sigmask): Undefine if defined, for MinGW64.

nt/inc/mingw_time.h: New file.
nt/inc/ms-w32.h: Include mingw_time.h instead of doing its job.
src/w32proc.c: Include mingw_time.h.
src/w32.c: Include mingw_time.h.
nt/inc/dirent.h (struct dirent) [__MINGW_MAJOR_VERSION >= 4]: Make
the layout of 'struct dirent' be compatible with MinGW32 runtime
versions 4.0 and later.
nt/inc/ms-w32.h (__MINGW_MAJOR_VERSION, __MINGW_MINOR_VERSION)
(__MINGW_PATCHLEVEL) [!__MINGW64_VERSION_MAJOR]: Define, if not
defined, but not for MinGW64.
(_USE_32BIT_TIME_T) [__MINGW64_VERSION_MAJOR]: Define, to force
use of 32-bit time_t type.

src/w32.c (mkostemp): New function.
(mktemp): Remove, no longer used. Most of the code reused in mkostemp.
Fixes: debbugs:15015
This simplifies Emacs a bit, since it no longer needs to worry
about closing file descriptors by hand in some cases.
It also fixes some unlikely races. Not all such races, as
libraries often open files internally without setting
close-on-exec, but it's an improvement.
* admin/merge-gnulib (GNULIB_MODULES): Add fcntl, pipe2.
(GNULIB_TOOL_FLAGS): Avoid binary-io, close. Do not avoid fcntl.
* configure.ac (mkostemp): New function to check for.
(PTY_OPEN): Pass O_CLOEXEC to posix_openpt.
* lib/fcntl.c, lib/getdtablesize.c, lib/pipe2.c, m4/fcntl.m4:
* m4/getdtablesize.m4, m4/pipe2.m4: New files, taken from gnulib.
* lib/gnulib.mk, m4/gnulib-comp.m4: Regenerate.
* nt/gnulib.mk: Remove empty gl_GNULIB_ENABLED_verify section;
otherwise, gnulib-tool complains given close-on-exec changes.
* nt/inc/ms-w32.h (pipe): Remove.
* nt/mingw-cfg.site (ac_cv_func_fcntl, gl_cv_func_fcntl_f_dupfd_cloexec)
(gl_cv_func_fcntl_f_dupfd_works, ac_cv_func_pipe2): New vars.
* src/alloc.c (valid_pointer_p) [!WINDOWSNT]:
* src/callproc.c (Fcall_process) [!MSDOS]:
* src/emacs.c (main) [!DOS_NT]:
* src/nsterm.m (ns_term_init):
* src/process.c (create_process):
Use 'pipe2' with O_CLOEXEC instead of 'pipe'.
* src/emacs.c (Fcall_process_region) [HAVE_MKOSTEMP]:
* src/filelock.c (create_lock_file) [HAVE_MKOSTEMP]:
Prefer mkostemp with O_CLOEXEC to mkstemp.
* src/callproc.c (relocate_fd) [!WINDOWSNT]:
* src/emacs.c (main): Use F_DUPFD_CLOEXEC, not plain F_DUPFD.
No need to use fcntl (..., F_SETFD, FD_CLOEXEC), since we're
now using pipe2.
* src/filelock.c (create_lock_file) [! HAVE_MKOSTEMP]:
Make the resulting file descriptor close-on-exec.
* src/lisp.h, src/lread.c, src/process.c (close_load_descs, close_process_descs):
* src/lread.c (load_descriptor_list, load_descriptor_unwind):
Remove; no longer needed. All uses removed.

New functions.

Make newly-created socket close-on-exec.
* src/sysdep.c (emacs_open, emacs_fopen):
Make new-created descriptor close-on-exec.
* src/w32.c (fcntl): Support F_DUPFD_CLOEXEC well enough for Emacs.
* src/w32.c, src/w32.h (pipe2): Rename from 'pipe', with new flags arg.
Fixes: debbugs:14803
* configure.ac: Remove -with-acl option, since Gnulib does that for
us now.
(LIBACL_LIBS): Remove; no longer needed.
* lib/Makefile.am (CLEANFILES, SUFFIXES): New (empty) macros,
for the benefit of the new ACL implementation.
* lib/makefile.w32-in (GNULIBOBJS): Add $(BLD)/acl-errno-valid.$(O).
($(BLD)/acl-errno-valid.$(O)): New rule.
* lib/acl-errno-valid.c, lib/acl-internal.h, lib/acl.h:
* lib/acl_entries.c, lib/errno.in.h, lib/file-has-acl.c:
* lib/qcopy-acl.c, lib/qset-acl.c, m4/acl.m4, m4/errno_h.m4:
New files, taken from gnulib.
* lib/gnulib.mk, m4/gnulib-comp.m4: Regenerate.
* admin/merge-gnulib (GNULIB_MODULES): Add qacl.
(GNULIB_TOOL_FLAGS): Do not avoid errno.
* etc/NEWS: Emacs is no longer limited to POSIX ACLs. --disable-acl,
not --without-acl, since we're now using Gnulib's implementation.
* nt/config.nt (HAVE_ACL_SET_FILE): Rename from HAVE_POSIX_ACL.
* nt/inc/ms-w32.h (EOPNOTSUPP): New macro.
* src/Makefile.in (LIB_ACL): New macro.
(LIBACL_LIBS): Remove.
(LIBES): Use LIB_ACL, not LIBACL_LIBS.
* src/fileio.c: Include <acl.h>.
Use HAVE_ACL_SET_FILE rather than HAVE_POSIX_ACL.
(ACL_NOT_WELL_SUPPORTED): Remove. All uses replaced by
!acl_errno_valid.
(Fcopy_file) [!WINDOWSNT]: Use qcopy_acl instead of rolling
it ourselves.
