	The next log entry shows the actual changes by Paul Eggert.

 Fix a problem with aliasing and vector headers.
 GCC 4.6.0 optimizes based on type-based alias analysis.  For
 example, if b is of type struct buffer * and v of type struct
 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
 != &v->size, and therefore "v->size = 1; b->size = 2; return
 v->size;" must therefore return 1.  This assumption is incorrect
 for Emacs, since it type-puns struct Lisp_Vector * with many other
 types.  To fix this problem, this patch adds a new type struct
 vector_header that documents the constraints on layout of vectors
 and pseudovectors, and helps optimizing compilers not get fooled
 by Emacs's type punning.  It also adds the macros XSETTYPED_PVECTYPE
 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
 src/lisp.h (XVECTOR_SIZE): New convenience macro.  All previous uses of
 XVECTOR (foo)->size replaced to use this macro, to avoid the hassle
 of writing XVECTOR (foo)->header.size.
 src/lisp.h: Say "vectorlike header" rather than "vector header.
 (struct vectorlike_header): Rename from struct vector_header.
 (XVECTORLIKE_HEADER_SIZE): Renamed from XVECTOR_HEADER_SIZE.
 All uses changed.
 (XVECTOR_HEADER_SIZE): New macro, for use in XSETPSEUDOVECTOR.
 (XSETTYPED_PVECTYPE): New macro, specifying the name of the size
 member.
 (XSETPVECTYPE): Rewrite in terms of new macro.
 (XSETPVECTYPESIZE): New macro, specifying both type and size.
 This is a bit clearer, and further avoids the possibility of
 undesirable aliasing.
 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR
 and XVECTOR_HEADER_SIZE.
 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
 since Lisp_Subr is a special case (no "next" field).
 (ASIZE): Rewrite in terms of XVECTOR_SIZE.
 (struct vector_header): New type.
 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
 object, to help avoid aliasing.
 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
 (SUBRP): Likewise, since Lisp_Subr is a special case.
 src/lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
 (struct Lisp_Hash_Table): Combine first two members into a single
 struct vector_header member.  All uses of "size" and "next" members
 changed to be "header.size" and "header.next".
 src/buffer.h (struct buffer): Likewise.
 src/font.h (struct font_spec, struct font_entity, struct font): Likewise.
 src/frame.h (struct frame): Likewise.
 src/process.h (struct Lisp_Process): Likewise.
 src/termhooks.h (struct terminal): Likewise.
 src/window.c (struct save_window_data, struct saved_window): Likewise.
 src/window.h (struct window): Likewise.
 src/alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
 src/buffer.c (init_buffer_once): Likewise.
 src/lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
 special case.
 src/process.c (Fformat_network_address): Use local var for size,
 for brevity.
 src/fns.c (vector): Remove; this old hack is no longer needed.
 src/bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.

* lisp/progmodes/which-func.el (which-function): Use
add-log-current-defun instead of add-log-current-defun-function,
which might not be defined.

(Multiline Font Lock):
* lispref/vol2.texi (Top):
* lispref/vol1.texi (Top):
* lispref/elisp.texi (Top): Update menu accordingly.

 src/w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
 New version that can reserve upto 2GB of heap space.
 etc/NEWS: Mention the new feature.

 leim/quail/latin-ltx.el <\beth, \gimel, \daleth>: Produce
 corresponding symbols rather than Hebrew letters.

 leim/quail/latin-ltx.el <\aleph>: Produce ALEF SYMBOL instead of
 HEBREW LETTER ALEF.

region between POS and (pos).
(tramp-do-copy-or-rename-file-out-of-band): Use `nil' position in
`tramp-process-actions' call.
(tramp-maybe-open-connection): Call `tramp-process-actions' with pos.

* net/tramp-smb.el (tramp-smb-maybe-open-connection): Use `nil'
position in `tramp-process-actions' call.

Fixes: debbugs:8535

* play/mpuz (mpuz-silent): Doc fix.
  (mpuz-mode-map): Move initialization into declaration.
  (mpuz-put-number-on-board): Rename parameter L to COLUMNS.
  (mpuz-letter-to-digit, mpuz-check-all-solved, mpuz-create-buffer):
  Fix typos in docstrings.

 src/s/ms-w32.h (localtime): Redirect to sys_localtime.
 src/w32.c: Include <time.h>.
 (sys_localtime): New function.

* sysdep.c (wait_for_termination): On GNU Hurd, kill returns -1 on zombies.
