This is a backport from the trunk, consisting of:
2012-11-17 Eli Zaretskii <eliz@gnu.org>
* nt/inc/sys/wait.h: New file, with prototype of waitpid and
definitions of macros it needs.
* nt/inc/ms-w32.h (wait): Don't define, 'wait' is not used anymore.
(sys_wait): Remove prototype.
* nt/config.nt (HAVE_SYS_WAIT_H): Define to 1.
* src/w32proc.c (create_child): Don't clip the PID of the child
process to fit into an Emacs integer, as this is no longer a
restriction.
(waitpid): Rename from sys_wait. Emulate a Posix 'waitpid' by
reaping only the process specified by PID argument, if that is
positive. Use PID instead of dead_child to know which process to
reap. Wait for the child to die only if WNOHANG is not in
OPTIONS.
(sys_select): Don't set dead_child.
* src/sysdep.c (wait_for_termination_1): Remove the WINDOWSNT portion,
as it is no longer needed.
* src/process.c (waitpid, WUNTRACED) [!WNOHANG]: Remove definitions,
no longer needed.
(record_child_status_change): Remove the setting of
record_at_most_one_child for the !WNOHANG case.

Fix a race condition that causes Emacs to mess up glib (Bug#8855).
This is a backport from the trunk.
The symptom is a diagnostic "GLib-WARNING **: In call to
g_spawn_sync(), exit status of a child process was requested but
SIGCHLD action was set to SIG_IGN and ECHILD was received by
waitpid(), so exit status can't be returned." The diagnostic
is partly wrong, as the SIGCHLD action is not set to SIG_IGN.
The real bug is a race condition between Emacs and glib: Emacs
does a waitpid (-1, ...) and reaps glib's subprocess by mistake,
so that glib can't find it. Work around the bug by invoking
waitpid only on subprocesses that Emacs itself creates.
* src/process.c (create_process, record_child_status_change):
Don't use special value -1 in pid field, as the caller now must
know the pid rather than having the callee infer it. The
inference was sometimes incorrect anyway, due to another race.
(create_process): Set new 'alive' member if child is created.
(process_status_retrieved): New function.
(record_child_status_change): Use it.
Accept negative 1st argument, which means to wait for the
processes that Emacs already knows about. Move special-case code
for DOS_NT (which lacks WNOHANG) here, from caller. Keep track of
processes that have already been waited for, by testing and
clearing new 'alive' member.
(CAN_HANDLE_MULTIPLE_CHILDREN): Remove, as record_child_status_change
now does this internally.
(handle_child_signal): Let record_child_status_change do all
the work, since we do not want to reap all exited child processes,
only the child processes that Emacs itself created.
* src/process.h (Lisp_Process): New boolean member 'alive'.
since all users are dead long ago.
* nsterm.h (struct x_output): Use the only dummy member.
* w32menu.c (pending_menu_activation): Remove since not
really used.
(set_frame_menubar): Adjust user.
* w32term.h (struct x_output): Drop outdated #if 0 code.
(struct w32_output): Use bitfields for explicit_parent,
asked_for_visible and menubar_active members. Drop
unused pending_menu_activation member.
* xterm.h (struct x_output): Drop outdated #if 0 code.
Use bitfields for explicit_parent, asked_for_visible,
has_been_visible and net_wm_state_hidden_seen members.
src/xdisp.c (set_cursor_from_row): Skip step 2 only if point is not
between bpos_covered and bpos_max. This fixes cursor display when
several display strings follow each other.
Check for `use-region-p' if `interactive' is non-nil.
(dired-unmark, dired-flag-file-deletion): Add optional arg
`interactive'. Call `dired-mark' with the arg `interactive'.
Fixes: debbugs:10624
src/.gdbinit (pgx): If the glyph's object is a string, display the
pointer to string data, rather than the value of the string object
itself (which barfs under CHECK_LISP_OBJECT_TYPE).
* admin/CPP-DEFINES (HAVE_CLOSEDIR, HAVE_DIRENT_H): Remove.
* admin/notes/copyright: Adjust to src/ndir.h -> nt/inc/dirent.h renaming.
* configure.ac: Do not check for dirent.h or closdir.
* nt/inc/dirent.h: Rename from ../src/ndir.h, with these changes:
(struct dirent): Rename from struct direct. All uses changed.
* nt/inc/sys/dir.h: Remove.
* src/dired.c: Assume HAVE_DIRENT_H.
(NAMLEN): Remove, replacing with ...
(dirent_namelen): New function. All uses changed. Use the GNU macro
_D_EXACT_NAMELEN if available, as it's faster than strlen.
(DIRENTRY): Remove, replacing all uses with 'struct dirent'.
(DIRENTRY_NONEMPTY): Remove. All callers now assume it's nonzero.
* src/makefile.w32-in (DIR_H): Remove. All uses replaced with
$(NT_INC)/dirent.h.
($(BLD)/w32.$(O)): Do not depend on $(SRC)/ndir.h.
* src/ndir.h: Rename to ../nt/inc/dirent.h.
* src/sysdep.h (closedir) [!HAVE_CLOSEDIR]: Remove.
Do not include <dirent.h>; no longer needed.
* src/w32.c: Include <dirent.h> rather than "ndir.h".

Patch by Christopher Schmidt <christopher@ch.ristopher.com>.
(wdired-finish-edit): Add marks for new file names to
`wdired-old-marks'. Restore marks using `dired-mark-remembered'
after `revert-buffer'.
(wdired-do-renames): Remove calls to `dired-remove-file',
`dired-add-file', `dired-add-entry'.

This is easier to follow, lines up better in the menu, and lets us
coalesce regions that switch at the same time. Give country
names, not "Vatican", as that's better for non-expert users. Use
names that are stable between the date of switch and now, e.g.,
Bohemia and Moravia (which existed then and now) and not
Czechoslovakia (which didn't exist then and doesn't exist now).
What is now the U.S. mostly did not switch at the same time as
Britain, so omit the U.S. Correct spelling of "Britain".
Catholic Switzerland was too much of a mess, so omit it.
(update_menu_bar, update_tool_bar): Use it to
simplify large 'if' statements.
(redisplay_internal): Generalize commonly used
'tail' and 'frame' local variables.
Gregorian-Julian switch.
(Customizing Calc): Mention the variable `calc-gregorian-switch'.
* calc/calc.el (calc-gregorian-switch): Refresh the Calc buffer
after the variable is changed.
src/indent.c (Fvertical_motion): If the starting position is covered
by a display string, return to one position before that, to avoid
overshooting it inside move_it_to.
