Problem reported by Ken Raeburn in:
http://lists.gnu.org/archive/html/emacs-devel/2016-11/msg00463.html
* src/emacs.c (heap_bss_diff) [CANNOT_DUMP]: Remove, as this is
not needed in the CANNOT_UNDUMP case. All uses removed. This
removes unwanted references to my_endbss and my_endbss_static,
which are not optimized away on some platforms.
Clean up some of the bitrot affecting the CANNOT_DUMP code. This
lets the build succeed again, and fixes the testing framework so
that most test cases now pass. About twenty test cases still
fail, though, and we still have Bug#24974.
* configure.ac (CANNOT_DUMP): Now empty if CANNOT_DUMP.
(SYSTEM_MALLOC): Now true if CANNOT_DUMP. There should no longer
be any point to messing with a private memory allocator unless
Emacs is dumping.
* src/alloc.c (alloc_unexec_pre, alloc_unexec_post, check_pure_size):
* src/image.c (reset_image_types):
* src/lastfile.c (my_endbss, _my_endbss, my_endbss_static):
Do not define if CANNOT_DUMP.
* src/emacs.c (might_dump) [CANNOT_DUMP]: Now always false and local.
(daemon_pipe) [!WINDOWSNT]: Now static.
* test/Makefile.in (mostlyclean): Remove *.tmp files.
(make-test-deps.mk): Elide CANNOT_DUMP chatter.
* src/xdisp.c (redisplay_internal): If all the frames were
successfully updated, reset the "garbaged" flag of each frame, to
make sure it doesn't stay set.
* src/w32term.c (w32_read_socket): Don't clear the frame if it's
"garbaged", since expose_frame won't redraw the foreground then.

# lisp/auth-source.el

* src/w32heap.c (getrlimit, setrlimit): New functions.
Include w32.h.
* src/emacs.c (main): Use 'rlim_t', not 'long', for values that
should be compatible with 'struct rlimit' members.
* nt/inc/sys/resource.h: New header file.
* nt/mingw-cfg.site (ac_cv_func_getrlimit, ac_cv_func_setrlimit):
Set to "yes".
* doc/lispref/os.texi (Time Calculations): Mention the meaning of
'nil' or a scalar number as the time-value argument. Add a
cross-reference to 'float-time' for computing a time difference as
a scalar number of seconds.
* src/editfns.c (Fformat_time_string, Ftime_less_p)
(Ftime_subtract, Ftime_add, Fdecode_time, Fcurrent_time_string)
(Fcurrent_time_zone): Mention in the doc strings the meaning of
nil argument and the fact that a time value can be a scalar number
of seconds since the epoch.
(Ftime_subtract): Mention 'float-time'.
This is intended for modern init systems such as systemd,
which manage many of the traditional aspects of daemon behavior
themselves. (Bug#2677)
* src/emacs.c (daemon_type): New integer.
(usage, standard_args): Add --old-daemon and --new-daemon.
(main): Handle --old-daemon and --new-daemon arguments.
Restrict all the forking and complicated daemon stuff to old-daemon.
(Fdaemon_initialized): Handle new-style daemon.
* src/lisp.h (IS_DAEMON, DAEMON_RUNNING) [!WINDOWNT]:
Replace daemon_pipe with daemon_type.
* doc/emacs/cmdargs.texi (Initial Options):
* doc/emacs/glossary.texi (Glossary):
* doc/emacs/misc.texi (Emacs Server):
* doc/lispref/display.texi (Window Systems):
* doc/lispref/os.texi (Startup Summary): Related doc updates.
* etc/NEWS: Mention this.
* etc/emacs.service: Use Type=simple and --new-daemon.
* src/fileio.c (file_name_case_insensitive_p): Try skipping the
Darwin code and instead using pathconf with _PC_CASE_SENSITIVE.
Leave in two alternatives conditionally compiled based on
DARWIN_OS_CASE_SENSITIVE_FIXME in case pathconf doesn't work.
* etc/PROBLEMS: Mention the possible problem with pathconf on
Mac OS X.
* doc/lispref/files.texi (Truenames): Simplify documentation,
to avoid giving too much platform-specific information that
may not be accurate anyway.
* src/fileio.c (file_name_case_insensitive_p): Use pathconf with
_PC_CASE_SENSITIVE if _PC_CASE_INSENSITIVE is not available.
Otherwise if one approach fails (e.g., with errno == EINVAL), fall
back on an alternative rather than returning false. Try skipping
the Darwin code, as it (1) no longer seems to be needed and (2)
does not seem to match the Apple documentation. Leave in two
alternatives conditionally compiled based on
DARWIN_OS_CASE_SENSITIVE_FIXME in case (1) or (2) is incorrect.
* src/gmalloc.c: Include <stdlib.h>, so it declares
hybrid_aligned_alloc (the definiens of the aligned_alloc macro),
so that GCC doesn't complain that hybrid_aligned_alloc is
defined without being declared.
* src/fileio.c (file_name_case_insensitive_p)
(Ffile_name_case_insensitive_p): New functions.
(Frename_file): Allow renames that simply change case when the
FILE argument is on a case-insensitive filesystem. (Bug#24441)
* lisp/dired-aux.el (dired-do-create-files): Use
'file-name-case-insensitive-p' instead of 'system-type' to check
for case-insensitivity. (Bug#24441)
* doc/lispref/files.texi (Truenames): Document
'file-name-case-insensitive-p'.
Problem reported by Ashish Shukla (Bug#24892). I tested
this on FreeBSD 11 x86-64 with HAVE_SBRK manually undefined.
* configure.ac (system_malloc): Set to 'yes' if there is no sbrk.
(sbrk): Check whether it exists.
* src/alloc.c (my_heap_start) [!GNU_LINUX]:
Do not define, since this function is now used only on GNU/Linux,
and sbrk might not exist on other platforms.
(malloc_initialize_hook) [!GNU_LINUX]:
Do not call my_heap_start, since its side effect will never be used.
(Fmemory_limit) [!HAVE_SBRK]: Do not call sbrk.
* src/unexelf.c (unexec) [!HAVE_SBRK]: Assume that nothing like
sbrk exists.
Problem reported by Philipp Stephani (Bug#24869).
* src/callproc.c (child_setup) [!DOS_NT]:
Call restore_nofile_limit in the child.
* src/process.c (nofile_limit) [HAVE_SETRLIMIT]: New static var.
(restore_nofile_limit): New function.
(init_process_emacs) [HAVE_SETRLIMIT]: Set the new var.
Apple changed the spelling of its operating system again, to "macOS",
effective with macOS 10.12 Sierra (2016-09-20). Change Emacs
documentation and comments to match this. Stick with older OS
spellings ("OS X", "Mac OS X") when talking about older releases where
the older names are more correct.
Emacs C code assumes C99 features, but has long used traditional
comments /* like this */ instead of C99-style comments // like this.
Stick with traditional comments for now, partly for style, partly as
it may be safer with compilers that are not fully in C99 mode.

src/syntax.c (scan_sexps_forward): When chars of syntax word are also flagged
as the start/end of two char comment delimiters, recognize a comment delimiter
in preference to a portion of a word. This fixes bug #24767.
* src/keyboard.c (Fposn_at_point): If pos-visible-in-window-p
returns a 6-member list for a partially visible glyph, pass the
sum of Y and RTOP to posn-at-x-y, since that's where the visible
portion of that glyph begins on display. (Bug#24804) (Bug#21832)
(Bug#23809)
