specpdl overflow here, to simplify callers; all callers changed.

Also, prefer report_file_errno to setting errno + report_file_error.

* process.c (create_process, wait_reading_process_output) [AIX]:
Remove obsolete SIGHUP-related  code, as Emacs no longer disables
SIGHUP, so EBADF is no longer acceptable here (it wouldn't work in
a multithreaded environment anyway).
* sysdep.c (emacs_close): It's not dangerous to invoke emacs_close (-1).

lisp/desktop.el: Minor fixes.

New macro and function, which emulates the POSIX_CLOSE_RESTART macro

(emacs_close): Use it.  This should fix the races on GNU/Linux and
on AIX and on future platforms that support POSIX_CLOSE_RESTART,
and it should avoid closing random victim file descriptors on
other platforms.

 partially-visible, but its text is completely visible, allow
 cursor to enter such a partially-visible line.

Syntax cleanup, mostly replacing macros with functions.

This removes the need for the syntax_temp hack.
* search.c: Include syntax.h after buffer.h, since syntax.h uses BVAR.
* syntax.c (SYNTAX_INLINE): New macro.
(SYNTAX_FLAGS_COMSTART_FIRST, SYNTAX_FLAGS_COMSTART_SECOND)
(SYNTAX_FLAGS_COMEND_FIRST, SYNTAX_FLAGS_COMEND_SECOND)
(SYNTAX_FLAGS_PREFIX, SYNTAX_FLAGS_COMMENT_STYLEB)
(SYNTAX_FLAGS_COMMENT_STYLEC, SYNTAX_FLAGS_COMMENT_STYLEC2)
(SYNTAX_FLAGS_COMMENT_NESTED, SYNTAX_FLAGS_COMMENT_STYLE)
(SYNTAX_COMEND_FIRST): Now functions, not macros.
(ST_COMMENT_STYLE, ST_STRING_STYLE, INTERVALS_AT_ONCE):
Now constants, not macros.
(syntax_temp) [!__GNUC__]: Remove.
(SYNTAX_PREFIX): Remove; all uses replaced by syntax_prefix_flag_p.
(syntax_prefix_flag_p): Move implementation of SYNTAX_PREFIX here.
(SET_RAW_SYNTAX_ENTRY, SET_RAW_SYNTAX_ENTRY_RANGE, SYNTAX_MATCH)
(SETUP_SYNTAX_TABLE, SETUP_SYNTAX_TABLE_FOR_OBJECT):
Move here from syntax.h; now functions, not macros.  Except for the
last function, these are static since only syntax.c uses them.
(syntax_multibyte): Rename from SYNTAX_WITH_MULTIBYTE_CHECK.
All uses changed.  Now a function, not a macro; use this fact
to simplify the code.
(scan_lists, scan_sexps_forward): Remove workarounds for ancient
compiler bugs; no longer relevant.
* syntax.h: Use INLINE_HEADER_BEGIN, INLINE_HEADER_END.
(SYNTAX_INLINE): New macro.
(struct gl_state_s, gl_state): Move earlier, so that it's in scope
for the new functions.  Use bool for boolean member.
(SYNTAX_ENTRY, SYNTAX, SYNTAX_WITH_FLAGS, SYNTAX_MATCH)
(SYNTAX_TABLE_BYTE_TO_CHAR, UPDATE_SYNTAX_TABLE_FORWARD)
(UPDATE_SYNTAX_TABLE_BACKWARD, UPDATE_SYNTAX_TABLE)
(SETUP_BUFFER_SYNTAX_TABLE):
Now extern inline functions, not macros.
(CURRENT_SYNTAX_TABLE, SYNTAX_ENTRY_INT):
Remove; all uses replaced by implementation.
(syntax_temp) [!__GNUC__]: Remove decl.
(SETUP_SYNTAX_TABLE_FOR_OBJECT): New decl.

Fix last patch.

Improve error messages.  (Bug#14808)

* net/tramp.el (tramp-current-connection): New defvar, moved from
tramp-sh.el.
(tramp-message-show-progress-reporter-message): Removed, not
needed anymore.
(tramp-error-with-buffer): Show message in minibuffer.  Discard
input before waiting.  Reset connection timestamp.
(with-tramp-progress-reporter): Improve messages.
(tramp-process-actions): Use progress reporter.  Delete process in
case of error.  Improve messages.

* net/tramp-sh.el (tramp-barf-if-no-shell-prompt): Use
condition-case.  Call `tramp-error-with-buffer' with vector and buffer.
(tramp-current-connection): Removed.
(tramp-maybe-open-connection): The car of
`tramp-current-connection' are the first 3 slots of the vector.

* progmodes/cfengine.el: Do not indent inside continued strings.

Add comment.

* emacs.c (main): Fix syntax error.

Auto-commit of generated files.

* Makefile.in (removenullpaths): Remove adjacent null paths.

Fixes: debbugs:14835

Timestamp fixes for undo.

* doc/lispref/text.texi (Undo):
Document (t . 0) and (t . -1) in buffer-undo-list.
* etc/NEWS: Changes to visited-file-modtime, set-visited-file-modtime.
* lisp/files.el (clear-visited-file-modtime): Move here from fileio.c.
* src/atimer.c (schedule_atimer):
* src/fileio.c (Ffile_newer_than_file_p):
Minor cleanup: use EMACS_TIME_LT so that we can remove EMACS_TIME_GT.
* src/buffer.c (buffer-undo-list): Document (t . 0) and (t . -1).
* src/fileio.c (Fclear_visited_file_modtime): Move to lisp/files.el.
(syms_of_fileio): Remove Sclear_visited_file_name.
(Fvisited_file_modtime): Return -1, not (-1 ...), when the visited
file doesn't exist; this avoids an ambiguity with negative timestamps.
(Fset_visited_file_modtime): Accept -1 and 0 as time-list arg.
* src/systime.h (make_emacs_time, invalid_emacs_time):
Don't assume struct timespec layout; POSIX doesn't guarantee it.
(EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE): Remove.
* src/undo.c (record_first_change): Push (visited-file-modtime) onto
undo list rather than reimplementing it by hand, incorrectly.

Fixes: debbugs:14824

* files.el (require-final-newline): Allow safe local value.

Fixes: debbugs:14834

Avoid nexted functions in AC_LANG_PROGRAM test for Windows headers.

 configure.ac (HAVE_W32): Avoid nested functions (the second
 argument of AC_LANG_PROGRAM is already expanded inside a
 function).

Fixes: debbugs:14830

Port recent close-on-exec changes to Cygwin.
