+
+ * emacs.c: Use execvp, not execv, when DAEMON_MUST_EXEC, so that
+ daemon mode works on cygw32 when Emacs is installed and not just
+ during development.

+
+ Avoid file time stamp bug on MS-Windows (Bug#13149).
+ * fileio.c (Fwrite_region): Don't use the heuristic on empty files,
+ as FAT32 doesn't update time stamps when truncating them.
+ Also, check that a file time stamp is not a multiple of 100 ns;
+ this should catch all instances of the problem on MS-Windows,
+ as its native file system resolution is 100 ns or worse, and
+ checking for a non-multiple of 100 ns should impose only a small
+ overhead on systems with ns resolution.

+
+ Avoid encoding file names on MS-Windows when they need to be run
+ through dostounix_filename.
+ * w32.c (normalize_filename): Accept an additional argument
+ MULTIBYTE; if non-zero, traverse the file name by bytes and don't
+ downcase it even if w32-downcase-file-names is non-nil.
+ (dostounix_filename): Accept an additional argument MULTIBYTE and
+ pass it to normalize_filename.
+ (emacs_root_dir): Adjust.
+
+ * msdos.h (dostounix_filename): Adjust prototype.
+
+ * w32.h (dostounix_filename): Adjust prototype.
+
+ * msdos.c (dostounix_filename): Accept an additional argument and
+ ignore it.
+ (init_environment): Adjust callers of dostounix_filename.
+
+ * fileio.c (Ffile_name_directory, file_name_as_directory)
+ (directory_file_name, Fexpand_file_name)
+ (Fsubstitute_in_file_name): [DOS_NT] Adjust call to
+ dostounix_filename.
+ [WINDOWSNT]: Downcase file names if w32-downcase-file-names is
+ non-nil.
+ (Fsubstitute_in_file_name): [DOS_NT] Don't downcase environment
+ variables, as egetenv is case-insensitive for DOS_NT.
+
+ * dired.c (file_name_completion): Don't call Fdirectory_file_name
+ with an encoded file name.
+
+ * w32proc.c (Fw32_short_file_name, Fw32_long_file_name): Adjust
+ calls to dostounix_filename.
+
+ * w32fns.c (Fx_file_dialog): Adjust call to dostounix_filename.
+
+ * unexw32.c (unexec): Adjust call to dostounix_filename.
+
+ * termcap.c (tgetent) [MSDOS]: Adjust call to dostounix_filename.
+
+ * emacs.c (decode_env_path) [DOS_NT]: Adjust call to
+ dostounix_filename.
+
+ * callproc.c (Fcall_process) [MSDOS]: Adjust call to
+ dostounix_filename.
+
+ * callproc.c (Fcall_process): Make sure program name in PATH and
+ new_argv[0] is encoded, if needed. Otherwise, un-encoded string
+ is passed to exec/spawnve, which fails unless the file-name
+ encoding is UTF-8.
+
+ * w32proc.c (sys_spawnve): Make sure escape_char is initialized,
+ even if w32-quote-process-args is nil.

+
+ Fix timestamp bug when write-region appends nothing (Bug#13149).
+ * fileio.c (Fwrite_region): When neither O_EXCL nor O_TRUNC is used,
+ the file's time stamp doesn't change if Emacs happens to write nothing
+ to the file, and on a buggy file system this could cause Emacs to
+ incorrectly infer that the file system doesn't have the bug.
+ Avoid this problem by inhibiting the inference in this case.

+
+ * window.h (struct window): Convert base_line_number, base_line_pos
+ and column_number_displayed members from Lisp_Object to ptrdiff_t.
+ Convert region_showing member from Lisp_Object to bitfield.
+ Remove sequence_number member. Adjust comments.
+ * window.c (sequence_number): Remove.
+ (make_window): Initialize column_number_displayed.
+ * print.c (print_object): Follow the printed representation of
+ frames and print window pointer to distinguish between windows.
+ (adjust_window_count): Invalidate base_line_pos. Adjust comment.
+ * xdisp.c (wset_base_line_number, wset_base_line_pos)
+ (wset_column_number_displayed, wset_region_showing): Remove.
+ (window_buffer_changed, mode_line_update_needed, redisplay_internal)
+ (try_scrolling, try_cursor_movement, redisplay_window)
+ (try_window_reusing_current_matrix, try_window_id, display_line)
+ (display_mode_lines, decode_mode_spec): Adjust users.
+ * .gdbinit (pwinx): Do not print sequence_number.

+
+ Use fdopendir, fstatat and readlinkat, for efficiency (Bug#13539).
+ * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): Remove.
+ * dired.c: Include <fcntl.h>.
+ (open_directory): New function, which uses open and fdopendir
+ rather than opendir. DOS_NT platforms still use opendir, though.
+ (directory_files_internal, file_name_completion): Use it.
+ (file_attributes): New function, with most of the old Ffile_attributes.
+ (directory_files_internal, Ffile_attributes): Use it.
+ (file_attributes, file_name_completion_stat): First arg is now fd,
+ not dir name. All uses changed. Use fstatat rather than lstat +
+ stat.
+ (file_attributes): Use emacs_readlinkat rather than Ffile_symlink_p.
+ * fileio.c: Include <allocator.h>, <careadlinkat.h>.
+ (emacs_readlinkat): New function, with much of the old
+ Ffile_symlink_p, but with an fd argument for speed.
+ It uses readlinkat rather than careadlinkatcwd, so that it
+ need not assume the working directory.
+ (Ffile_symlink_p): Use it.
+ * filelock.c (current_lock_owner): Use emacs_readlinkat
+ rather than emacs_readlink.
+ * lisp.h (emacs_readlinkat): New decl.
+ (READLINK_BUFSIZE, emacs_readlink): Remove.
+ * sysdep.c: Do not include <allocator.h>, <careadlinkat.h>.
+ (emacs_norealloc_allocator, emacs_readlink): Remove.
+ This stuff is moved to fileio.c.
+ * w32.c (fstatat, readlinkat): New functions.
+ (careadlinkat): Don't check that fd == AT_FDCWD.
+ (careadlinkatcwd): Remove; no longer needed.
+

+
+ * fileio.c (choose_write_coding_system): Make it callable from Lisp.
+ (Fwrite_region): Update for new choose_write_coding_system args.
+ Move the last piece of choose_write_coding_system here. (Bug#13522)
+ (syms_of_fileio): Add choose-write-coding-system.
+

* w32.c (sys_open): Zero out the flags for the new file descriptor.
