Revert changes to w32proc.c done since 2012-11-30T09:23:15Z!eliz@gnu.org.
Do NOT merge to trunk!
src/w32proc.c (new_child): Remove the loop that attempted to salvage
slots of dead processes.
(new_child, delete_child, find_child_pid): Don't insist on
procinfo.hProcess be NULL for a process slot to be considered
inactive, or be non-NULL to be considered active.
(reader_thread): Don't set the FILE_AT_EOF flag of a file
descriptor if the corresponding child was deleted and its
char_avail handle is NULL.
(reap_subprocess): Don't reset the FILE_AT_EOF flag.
(sys_select): Don't pass a NULL process handle to
WaitForMultipleObjects.

* lisp/font-lock.el (lisp-font-lock-keywords-1, lisp-font-lock-keywords-2):
Don't assume all identifier chars have syntax word.
* lisp/emacs-lisp/lisp-mode.el (lisp-mode-variables):
Remove bar-not-symbol. Adjust callers.
(lisp-mode-variables): Don't set a font-lock-syntax-table.
src/xdisp.c (x_draw_vertical_border): For a window that is neither
the leftmost nor the rightmost, redraw both the left and the right
vertical borders.
* lisp/image.el (image-animated-types): Remove.
(image-multi-frame-p): Rename from image-animated-p, and generalize.
(image-animated-p): Make obsolete alias.
(image-animate, image-nth-frame, image-animate-timeout):
Use image-multi-frame-p.
(image-animate-timeout): If no delay, use image-default-frame-delay.
* lisp/image-mode.el (image-mode, image-toggle-animation):
Use image-multi-frame-p.
(image-mode): Adjust startup message for a multi-frame image.
* lisp/gnus/shr.el (shr-put-image): Only animate images that specify a delay.
This is consistent with the old image-animated-p behavior.
* etc/NEWS: Add placeholder for this.
Fixes: debbugs:10739
(tramp-get-connection-property): Use it.
* net/tramp-compat.el (top): Require 'trampver.
* net/tramp-sh.el (tramp-remote-process-environment): Set

See http://lists.gnu.org/archive/html/emacs-devel/2013-02/msg00293.html
and the following discussion for the details.
src/w32.c (set_errno): Reset h_errno and don't set it to any other
value. Set errno instead.
(check_errno): Reset h_errno.
(sys_socket, socket_to_fd, sys_bind, sys_connect)
(sys_gethostname, sys_getservbyname, sys_getpeername)
(sys_shutdown, sys_setsockopt, sys_listen, sys_getsockname)
(sys_accept, sys_recvfrom, sys_sendto, fcntl, sys_read): Don't set
h_errno.
(sys_gethostbyname): Set h_errno only errors detected.
* lisp/replace.el (read-regexp): Tighten the regexp that matches tag.
When tag is retrieved with `find-tag-default', use regexp that
matches tag at point. Also update docstring.
lisp/autorevert.el (auto-revert-notify-add-watch): With 'w32notify',
add watch for the file, not its parent directory, since w32notify
sets up the watch for the directory internally.
* lisp/image.el (image-default-frame-delay): New variable.
(image-animated-p): Use image-default-frame-delay.
(image-minimum-frame-delay): New constant.
(image-animate-timeout): Use image-minimum-frame-delay.
* lisp/image.el (image-current-frame): New variable.
(image-animate-timeout): Set image-current-frame.
* lisp/image-mode.el (image-mode): For animated images,
display a frame counter via mode-line-process.
minor mode has been enabled, call the minor mode function for a new
buffer once only, after the major mode hook, whilst allowing that hook
explicitly to disable the minor mode.
(MODE-disable-in-buffer): new (generated) function.
(disable-MODE): new (generated) buffer local variable.
* lisp/icomplete.el (icomplete-minibuffer-map): Unbind `C-s' and `C-r'.
Bind `C-.' and `C-,' to `icomplete-forward-completions' and
`icomplete-backward-completions'.
* lisp/ido.el (ido-init-completion-maps): Bind `C-.' and `C-,' to
`ido-next-match' and `ido-prev-match' resply.
* lisp/iswitchb.el (iswitchb-read-buffer): Bind `C-.' and `C-,' to
`iswitchb-next-match' and `iswitchb-prev-match' resply.
* lisp/icomplete.el (icomplete-minibuffer-map): Unbind `C-s' and `C-r'.
Bind `C-.' and `C-,' to `icomplete-forward-completions' and
`icomplete-backward-completions'.
* lisp/ido.el (ido-init-completion-maps): Bind `C-.' and `C-,' to
`ido-next-match' and `ido-prev-match' resply.
* lisp/iswitchb.el (iswitchb-read-buffer): Bind `C-.' and `C-,' to
`iswitchb-next-match' and `iswitchb-prev-match' resply.
src/w32proc.c (new_child): Free up to 2 slots of dead processes at a
time. Improve diagnostics in DebPrint.
(reader_thread): If cp->char_avail is NULL, set the FILE_AT_EOF
flag, so that sys_select could have a chance of noticing that this
process is dead, and call a SIGCHLD handler for it. Improve
diagnostics in DebPrint.
(reap_subprocess): Reset the FILE_AT_EOF flag set by
reader_thread.
(sys_select): Watch a process whose procinfo.hProcess is non-NULL
even if its char_avail is NULL. Allows to reap subprocesses that
were forcibly deleted by delete-process. (Bug#13546)
src/w32.c (sys_socket, sys_bind, sys_connect, sys_gethostname)
(sys_gethostbyname, sys_getservbyname, sys_getpeername)
(sys_shutdown, sys_setsockopt, sys_listen, sys_getsockname)
(sys_accept, sys_recvfrom, sys_sendto, fcntl): In case of failure,
make sure errno is set to an appropriate value. (Bug#13546)
(socket_to_fd): Add assertion against indexing fd_info[] with a
value that is out of bounds.
(sys_accept): If fd is negative, do not set up the child_process
structure for reading.
Since file-newer-than-p returns non-nil if FILE2 does not exist,
the actual fix for bug#5338 is just a one-liner. But there is no test
case or explanation of what the issue actually is in bug#5338, so one
has to wonder if the initial (file-exists-p fortune-dat) test was
there for a reason...
The bug was reported for AIX before today's changes.
I reproduced the problem on Fedora 17 x86-64 when setting
GC_MARK_STACK by hand, and I presume it occurs with default
configurations on HP-UX and Unixware.
Trunk fix on 2013-01-14 by Dmitry Antipov <dmantipov@yandex.ru>:
Fix compilation with GC_MARK_STACK == GC_USE_GCPROS_AS_BEFORE.
* eval.c (eval_sub): Protect `form' from being GCed before its
car and cdr becomes protected with the backtrace entry.
Fixes: debbugs:13650
* configure.ac (DATA_START, DATA_SEG_BITS): Set to 0x20000000 on AIX.
(GC_MARK_STACK): Do not set to GC_USE_GCPROS_AS_BEFORE, as that
runs afoul of some other bug in Emacs, and the default value
GC_MAKE_GCPROS_NOOPS has been tested and works.
* src/lisp.h (XPNTR) [!USE_LSB_TAG && DATA_SEG_BITS]:
Fix bug introduced in 2012-07-27 change. DATA_SEG_BITS, if set,
was #undeffed earlier, so it cannot be used as a macro here.
Use the constant and not the macro. Tested on AIX.
* src/unexaix.c: Revert 2013-02-11 and 2013-02-12 changes to this
file. They're almost surely OK but we're just before a release so
we should avoid changes unless they're clearly needed. Instead,
make the following minor change:
(ADDR_CORRECT): New macro.
Fixes: debbugs:13650
