* src/xterm.h (struct x_output): Surround handlebox_widget with
#ifdef HAVE_GTK_HANDLE_BOX_NEW. toolbar_is_packed is new,
toolbar_in_hbox is bool.
* configure.ac (TEMACS_LDFLAGS2): Don't define.
(LIBS_GNUSTEP): Set for GNUstep and substitute.
(LD_SWITCH_SYSTEM_TEMACS): Don't set for GNUstep.
* src/Makefile.in (TEMACS_LDFLAGS2): Remove.
(LIBS_GNUSTEP): Define.
(LIBES): Add $(LIBS_GNUSTEP).
(temacs$(EXEEXT)): Use $(LDFLAGS) instead of $(TEMACS_LDFLAGS2).
src/fileio.c (Fset_file_selinux_context, Fset_file_acl): Return t if
file's SELinux context or ACLs successfully set, nil otherwise.
lisp/files.el (backup-buffer-copy, basic-save-buffer-2): If
set-file-extended-attributes fails, fall back on set-file-modes
instead of signaling an error.
doc/lispref/files.texi (Changing Files): Document the return values of
set-file-selinux-context and set-file-acl.
src/xdisp.c (set_cursor_from_row): Don't confuse a truncation or
continuation glyph on a TTY with an indication of an empty line.
src/dispextern.h: Improve commentary to glyph->charpos and
glyph->object.
only if it's really needed.
* frame.h (enum output_method): Remove output_mac member since
it's a leftover from the deleted code.
* frame.c (Fframep): Adjust user here ...
* terminal.c (Fterminal_live_p): ... and here.
* coding.c (Qmac): Now here because it's only used to denote
end-of-line encoding type.
(syms_of_coding): DEFSYM it.
* frame.h (Qmac): Remove duplicated declaration.
src/fileio.c (file_name_as_directory, directory_file_name): Accept
an additional argument MULTIBYTE to indicate whether the input C
came from a multibyte or a unibyte Lisp string; all callers
adjusted. Don't assume the input string is always multibyte.
(Ffile_name_directory) [DOS_NT]: Handle unibyte strings correctly:
don't ENCODE_FILE them, and return a unibyte string if the input
was unibyte.
(Fexpand_file_name): Don't mix unibyte with multibyte strings, and
don't assume the input strings will always be multibyte. If the
input strings are multibyte, decode strings obtained from C
library functions.
* buffer.c (Fget_buffer_create): Use it to set compact field of
struct buffer_text to avoid accessing an uninitialized value
when compact_buffer is called for the first time.
(compact_buffer): Use convenient BUF_COMPACT and BUF_MODIFF.
src/w32.c (acl_set_file): If setting the file security descriptor
fails, and the new DACL is identical to the existing one, silently
return success. This fixes problems for users backing up their
own files without having the necessary privileges for setting
security descriptors.
src/w32proc.c (reader_thread): Do not index fd_info[] with negative
values.
(reader_thread): Exit when cp->status becomes STATUS_READ_ERROR
after WaitForSingleObject returns normally. This expedites reader
thread shutdown when delete_child triggers it.
(reap_subprocess): More accurate commentary for why we call
delete_child only when cp->fd is negative.
src/w32.c (sys_close): Do not call delete_child on a subprocess
whose handle is not yet closed. Instead, set its file descriptor
to a negative value, so that reap_subprocess will call
delete_child on that subprocess when its SIGCHLD arrives. This
avoids closing handles used for communications between sys_select
and reader_thread, which doesn't give sys_select a chance to
notice that the process exited and invoke the SIGCHLD handler for
it.
src/w32proc.c (new_child, delete_child, find_child_pid): For a
subprocess, consider its slot being in use as long as its process
handle (procinfo.hProcess) is not NULL. This avoids reusing the
slot when a new process is started immediately after killing
another one, without waiting enough time for the first process to
be reaped and resources allocated for it be orderly freed.

* international/mule-cmds.el (read-char-by-name): Signal an error
if the user does not supply a valid character.
* editfns.c (Finsert_char): Since read-char-by-name now signals an
error for invalid chars, don't check for a nil return value.

src/w32.c (acl_get_file, acl_set_file): Run the file name through
map_w32_filename, and resolve any symlinks in the file name, like
Posix platforms do.
(acl_set_file): Call revert_to_self, if any privileges were
enabled.

src/fileio.c (Fcopy_file) [WINDOWSNT]: Support copying ACLs.
nt/inc/sys/acl.h: New file.
nt/inc/ms-w32.h (ENOTSUP): Define if undefined.
nt/config.nt (HAVE_POSIX_ACL): Define.
doc/lispref/files.texi (File Attributes, Changing Files): Update to include
MS-Windows support for ACLs.
With the 2012-12-03 fix for Bug#12980 in place, an old workaround
for some of that bug's symptoms can now cause Emacs to abort.
Remove the workaround.
* process.c (wait_reading_process_output): Don't reraise SIGCHLD.
The bug that caused SIGCHLD to get lost has been fixed, and the
workaround for it can now cause Emacs to abort.
