	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.

	Timestamp fixes for undo (Bug#14824).
	* atimer.c (schedule_atimer):
	* fileio.c (Ffile_newer_than_file_p):
	Minor cleanup: use EMACS_TIME_LT so that we can remove EMACS_TIME_GT.
	* buffer.c (buffer-undo-list): Document (t . 0) and (t . -1).
	* 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.
	* 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.
	* undo.c (record_first_change): Push (visited-file-modtime) onto
	undo list rather than reimplementing it by hand, incorrectly.

2013-07-07  Paul Eggert  <eggert@cs.ucla.edu>

	Make file descriptors close-on-exec when possible (Bug#14803).
	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.
	* alloc.c (valid_pointer_p) [!WINDOWSNT]:
	* callproc.c (Fcall_process) [!MSDOS]:
	* emacs.c (main) [!DOS_NT]:
	* nsterm.m (ns_term_init):
	* process.c (create_process):
	Use 'pipe2' with O_CLOEXEC instead of 'pipe'.
	* emacs.c (Fcall_process_region) [HAVE_MKOSTEMP]:
	* filelock.c (create_lock_file) [HAVE_MKOSTEMP]:
	Prefer mkostemp with O_CLOEXEC to mkstemp.
	* callproc.c (relocate_fd) [!WINDOWSNT]:
	* 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.
	* filelock.c (create_lock_file) [! HAVE_MKOSTEMP]:
	Make the resulting file descriptor close-on-exec.
	* lisp.h, lread.c, process.c (close_load_descs, close_process_descs):
	* lread.c (load_descriptor_list, load_descriptor_unwind):
	Remove; no longer needed.  All uses removed.
	* process.c (SOCK_CLOEXEC): Define to 0 if not supplied by system.
	(close_on_exec, accept4, process_socket) [!SOCK_CLOEXEC]:
	New functions.
	(socket) [!SOCK_CLOEXEC]: Supply a substitute.
	(Fmake_network_process, Fnetwork_interface_list):
	(Fnetwork_interface_info, server_accept_connection):
	Make newly-created socket close-on-exec.
	* sysdep.c (emacs_open, emacs_fopen):
	Make new-created descriptor close-on-exec.
	* w32.c (fcntl): Support F_DUPFD_CLOEXEC well enough for Emacs.
	* w32.c, w32.h (pipe2): Rename from 'pipe', with new flags arg.

	(move_it_in_display_line_to): When the last scanned display
	element fits exactly on the display line, and

	Do not tickle glib SIGCHLD handling if Cygwin (Bug#14569).
	This mostly consists of undoing recent changes.
	* callproc.c (Fcall_process):
	* process.c (create_process):
	Do not worry about catching SIGCHLD here, undoing previous change.
	* nsterm.m (ns_term_init): Re-catch SIGCHLD, undoing previous change.
	* process.c, process.h (catch_child_signal):
	No longer extern if !NS_IMPL_GNUSTEP, undoing 06-22 change.
	* process.c (catch_child_handler): Don't worry about being called
	lazily and do not assume caller has blocked SIGCHLD, undoing
	previous change.  Move first-time stuff back to
	init_process_emacs, undoing 06-22 change.  If CYGWIN, do not
	tickle glib, as that causes Cygwin bootstrap to fail.  Do not
	set lib_child_handler if it's already initialized, which may
	help avoid problems on GNUStep.

	A more-conservative workaround for Cygwin SIGCHLD issues (Bug#14569).
	* callproc.c (Fcall_process):
	* process.c (create_process):
	Make sure SIGCHLD is caught before we fork,
	since Emacs startup no arranges to catch SIGCHLD.
	* process.c (lib_child_handler): Initialize to null, not to
	dummy_handler.
	(catch_child_signal): Allow self to be called lazily.
	Do nothing if it's already been called.
	Assume caller has blocked SIGCHLD (all callers do now).
	* emacs.c (main): Do not catch SIGCHLD here; defer it until
	just before it's really needed.
	* nsterm.m (ns_term_init): No need to re-catch SIGCHLD here,
	since it hasn't been caught yet.

	Try to avoid malloc SEGVs on Cygwin (Bug#14569).
	* callproc.c, process.h (block_child_signal, unblock_child_signal):
	Now extern.
	* emacs.c (main): Catch SIGCHLD just before initializing gfilenotify.
	* process.c (catch_child_signal): Block SIGCHLD while futzing with
	the SIGCHLD handler, since the code is not atomic and (due to glib)
	signals may be arriving now.
	* sysdep.c (init_signals): Do not catch child signals here;
	'main' now does that later, at a safer time.

	Clean up SIGCHLD handling a bit (Bug#14569).
	* process.c, process.h (catch_child_signal):
	Now always extern, even if !NS_IMPL_GNUSTEP.
	* process.c (catch_child_signal): Move glib tickler here from
	init_process_emacs, so that it's done earlier in Emacs
	initialization.  Also move the noninteractive && !initialized
	check here from init_process_emacs.  This is all a bit cleaner for
	GNUish platforms, and I hope it works around the Cygwin bug.
	* sysdep.c (init_signals): Invoke catch_child_signal here, so
	that glib signal handling is tickled before glib creates threads.

	Use C99-style flexible array members if available.
	This avoids some subtle aliasing issues, which typically
	aren't a problem with GCC but may be a problem elsewhere.
	* alloc.c (sdata): New typedef, replacing the old struct sdata.
	It is a struct if GC_CHECK_STRING_BYTES, a union otherwise.
	In either case, it uses a flexible array member rather than
	the old struct hack.  All uses changed.
	(SDATA_NBYTES, sweep_strings) [!GC_CHECK_STRING_BYTES]:
	Adjust to sdata reorganization.
	* alloc.c (VBLOCK_BYTES_MIN, allocate_vectorlike, Fgarbage_collect):
	Use offsetof (struct, flex_array_member), not sizeof (struct), as
	that ports better to pre-C99 non-GCC.
	* chartab.c (Fmake_char_table, make_sub_char_table, copy_char_table):
	Use CHAR_TABLE_STANDARD_SLOTS rather than its definition,
	as the latter has changed.
	* conf_post.h (FLEXIBLE_ARRAY_MEMBER): Move here from w32.c,
	and port better to pre-C99 GCC.
	* image.c (struct xpm_cached_color):
	* lisp.h (struct Lisp_Vector, struct Lisp_Bool_Vector)
	(struct Lisp_Char_Table, struct Lisp_Sub_Char_Table):
	Use FLEXIBLE_ARRAY_MEMBER.
	* lisp.h (string_bytes) [GC_CHECK_STRING_BYTES]:

	Don't stuff ptrdiff_t into int.
	(syntax_spec_code, syntax_code_spec): Now const.

	* eval.c (init_eval_once, grow_specpdl): Allocate a specbinding

	(unbind_to): Do not copy the binding; not needed, now that we

	* fileio.c (Fwrite_region): Use ptrdiff_t, not int, for specpdl count.
	* lisp.h (BITS_PER_PTRDIFF_T): Remove; no longer needed.
	(union specbinding): Rename from struct specbinding.  Redo layout
	to avoid the need for 'ptrdiff_t nargs : BITS_PER_PTRDIFF_T - 1;',
	which is not portable.  With Sun C 5.12 32-bit sparc, the
	declaration causes nargs to be an unsigned bitfield, a behavior
	that the C standard allows; but Emacs wants nargs to be signed.
	The overall type is now a union of structures rather than a

	* buffer.c (Qoverlayp):
	* data.c (Qsubrp):
	* fns.c (Qhash_table_p):
	* window.c (Qwindow_configuration_p):
	Now static.
	* lisp.h: Remove the abovementioned defns and decls.

	Use functions, not macros, for XINT etc. (Bug#11935).
	In lisp.h, prefer functions to function-like macros, and
	constants to object-like macros, when either will do.  This:
	 . simplifies use, as there's no more need to worry about
	   arguments' side effects being evaluated multiple times.
	 . makes the code easier to debug on some platforms.
	However, when using gcc -O0, keep using function-like macros
	for a few critical operations, for performance reasons.
	This sort of thing isn't needed with gcc -Og, but -Og
	is a GCC 4.8 feature and isn't widely-enough available yet.
	* alloc.c (gdb_make_enums_visible) [USE_LSB_TAG]:
	Remove enum lsb_bits; no longer needed.
	(allocate_misc, free_misc): Don't use XMISCTYPE as an lvalue.
	* buffer.c (Qoverlap):
	* data.c (Qsubrp):
	* fns.c (Qhash_table_p):
	Now extern, so lisp.h can use these symbols.
	* dispextern.h: Include character.h, for MAX_CHAR etc.

	(GLYPH_CHAR, GLYPH_FACE, GLYPH_CODE_CHAR, GLYPH_CODE_FACE)
	(GLYPH_CHAR_VALID_P, GLYPH_CODE_P): Now functions, not macros.
	(GLYPH_MODE_LINE_FACE): Now enums, not macros.
	* eval.c (Fautoload): Cast XUNTAG output to intptr_t, since
	XUNTAG now returns void *.

	(lisp_h_CHECK_NUMBER CHECK_SYMBOL, lisp_h_CHECK_TYPE)

	(CHECK_TYPE, CONSP, EQ, FLOATP, INTEGERP, MARKERP)
	(MISCP, NILP, SET_SYMBOL_VAL, SYMBOL_CONSTANT_P, SYMBOL_VAL, SYMBOLP)
	(VECTORLIKEP, XCAR, XCDR, XCONS, XHASH, XPNTR, XSYMBOL):
	If compiling via GCC without optimization, define these as macros
	in addition to inline functions.
	To disable this, compile with -DINLINING=0.
	(LISP_MACRO_DEFUN, LISP_MACRO_DEFUN_VOID): New macros.
	(check_cons_list) [!GC_CHECK_CONS_LIST]: Likewise.
	(make_number, XFASTINT, XINT, XTYPE, XUNTAG): Likewise, but
	hand-optimize only in the USE_LSB_TAG case, as GNUish hosts do that.
	(INTMASK, VALMASK): Now macros, since static values cannot be
	accessed from extern inline functions.
	(VALMASK): Also a constant, for benefit of old GDB.
	(LISP_INT_TAG_P): Remove; no longer needed as the only caller
	is INTEGERP, which can fold it in.

	* xdisp.c (pos_visible_p): Use the special code for finding the
	beginning of a display property or overlay for any "replacing"
	display property, not just for display strings.  This solves
	incorrect reporting of position by posn-at-point.  (Bug#14241)

	configure and build with -DUNEXELF_DEBUG without worrying about
	other modules that use DEBUG.
	(DEBUG_LOG) [UNEXELF_DEBUG]: New macro.  All debug code that prints
	possibly-wide integers now uses it instead of plain fprintf.
	(entry_address): New function, which avoids problems with 32-bit
	overflow on 64-bit hosts.
	(OLD_SECTION_H, NEW_SECTION_H, NEW_PROGRAM_H): Use it.
	(round_up): Don't assume the remainder fits in int.

	(unexec): Don't assume file sizes fit in int or size_t.
	Omit unnecessary trailing newline in 'fatal' format.
	Use strerror rather than outputting decimal error number.
	Remove unused code when emacs is not defined;
	this file relies on Emacs now.
	Don't assume e_phnum and e_shnum are positive.

	* regex.c: Fix problems when DEBUG is defined.
	(extract_number, extract_number_and_incr): Define regardless of
	whether DEBUG is defined; that's simpler and makes the code less
	likely to go stale in the normal case when DEBUG is not defined.
	Return int rather than taking an int * arg.  All callers changed.
	(DEBUG_PRINT1, DEBUG_PRINT2, DEBUG_PRINT3, DEBUG_PRINT4):
	Remove, replacing with ...
	(DEBUG_PRINT): New macro.  All callers changed.
	(DEBUG_COMPILES_ARGUMENTS): New macro.

	(POP_FAILURE_REG_OR_COUNT, PUSH_FAILURE_POINT) [DEBUG]:
	(POP_FAILURE_POINT, re_match_2_internal) [DEBUG]:
	Don't assume ptrdiff_t, size_t, and long are the same width as int.
	(POINTER_TO_OFFSET): Return ptrdiff_t, not regoff_t.
	This matters only when DEBUG is defined.

	* fileio.c (syms_of_fileio): Implement this.
	* filelock.c (create_lock_file): If symbolic links don't work, so
	we use a regular file as a lock file, do not fsync the lock file;
	it's not needed.
