* lisp.h (build_local_string): Rename to ...
(make_local_string): ... this macro.
(build_local_string, scoped_list1, scoped_list3): New macros.
(toplevel) [USE_STACK_LISP_OBJECTS]: Define all new macros
and functions as such, use regular fallbacks otherwise.
* alloc.c (verify_alloca) [USE_STACK_LISP_OBJECTS]: Define
conditionally.

Respect MAX_ALLOCA and fall back to regular GC for large objects.
* character.h (parse_str_as_multibyte): Move prototype to ...
* lisp.h (parse_str_as_multibyte): ... here.
(struct Lisp_Cons): Add GCALIGNED attribute if supported.
(scoped_cons, scoped_list2, build_local_vector, build_local_string):
New macros.
(scoped_cons_init, pointer_valid_for_lisp_object, local_vector_init)
(local_string_init): New functions.
* alloc.c (verify_alloca) [ENABLE_CHECKING]: New function.
(init_alloc_once): Call it.

[USE_LUCID]: Revert 2014-04-02 change (Bug#18403).  Add comment.
(x_delete_terminal): Do not close X connection fd (Bug#18403).
Add eassert and mark dpyinfo as dead only if it was alive.

* lisp/progmodes/sql.el (sql-default-directory): New user option.
(sql-product-interactive): Bind `default-directory' to it to
enable remote connections using Tramp.

and bind the command to C-c C-z.

 and fancy display.
* diary-lib.el (diary-live-p): Doc fix.

Fixes: debbugs:18381

* coding.c (growable_destination): New function.
(produce_chars): Use it for sanity checks.  Do not fiddle with
dst_end if the source and destination are both nil, as it's
the caller's responsibility to avoid overlap.
* keyboard.c (read_decoded_event_from_main_queue):
The destination must be MAX_MULTIBYTE_LENGTH times the max source
length, not 4 times, to prevent decode_coding_c_string from trying
to reallocate a destination.  This removes the need for the FIXME.

Fixes: debbugs:18410

All callers simplified.  Add a comment about exec_failed, vfork,
and alloca.

* xselect.c (x_fill_property_data): Don't let sign bit of negative
XCDR bleed into XCAR's encoded value.  Improve checks for
out-of-range data while we're at it.

is CONSP.

 src/dispnew.c (prepare_desired_row): When MODE_LINE_P is zero,
 always make sure the marginal areas of the row are in sync with
 what the window wants.

 src/callproc.c (child_setup) [WINDOWSNT]: Don't call exec_failed if
 'alloca' gets passed arguments larger than MAX_ALLOCA.
 src/font.c (MAX): Define if not defined elsewhere.

here for destination buffer, to work around what appears to be a
bug in decode_coding_c_string when the source and destination are
both C strings.

* keyboard.c (echo_add_key, menu_bar_items, tool_bar_items)

and `string-collate-lessp'.

* configure.ac: Assume verbose output for older Automake.

(fns-tests-collate-strings, fns-tests-collate-sort): Use it.

This follows up on the recent thread in emacs-devel on alloca; see:
http://lists.gnu.org/archive/html/emacs-devel/2014-09/msg00042.html
This patch also cleans up alloca-related glitches noted while
examining the code looking for unbounded alloca.
